#geowebchat transcript, 6 October 2015: “armchair mapping”

@mappingmashups Oct 02, 10:18am Next #geowebchat we’ll discuss “armchair mapping”. What are the challenges in remote mapping for @openstreetmap? Tue Oct 6 12pm PDT. Pls RT!

@geoawesomeness Oct 02, 10:23am This #geowebchat seems really interesting! RSVP #GeoGeeks! Via @mappingmashups #geoawesomeness

@osmcbba Oct 03, 1:07pm Sigue el próximo #geowebchat: “mapeo de sillón” o “mapeo remoto”. Únete Mar 6 Oct 12h UTC-7. wiki.openstreetmap.org/wiki/Armchair_… via @mappingmashups

@mappingmashups Oct 05, 10:53am A fascinating (& long) email thread about remote mapping: lists.openstreetmap.org/pipermail/talk… relevant to our upcoming #geowebchat (Tue Oct 6, 12pm PDT)

@mappingmashups Oct 05, 10:57am RE remote mapping by @ricaji groundtruth.in/2015/06/05/osm… @gwilymeades place-memes.blogspot.de/2015/05/the-hu… @jbjensson joi.betra.is/?p=1769 #geowebchat

@mappingmashups Oct 06, 7:07am Today (Tue Oct 6) on #geowebchat we debate “armchair mapping” wiki.openstreetmap.org/wiki/Armchair_… What is it, & how do we do it well? Join us: noon PDT!

@mappingmashups Oct 06, 12:02pm Welcome everyone to today’s #geowebchat about remote mapping aka “armchair mapping” wiki.openstreetmap.org/wiki/Armchair_…

@mappingmashups Oct 06, 12:03pm As with every #geowebchat, make sure you use the hashtag in your tweets if you want to join the conversation. Or mute the hashtag to ignore.

@mappingmashups Oct 06, 12:05pm I recommend using a tool like @TweetChat to tweetchat.com/room/geowebchat to follow along with #geowebchat. Easier to track the conversation

@mappingmashups Oct 06, 12:05pm Two months ago on #geowebchat we discussed “outdoor mapping” mappingmashups.net/2015/08/04/geo… and many people asked, isn’t all mapping done outdoors?

@mappingmashups Oct 06, 12:07pm But especially in @openstreetmap, there is a lot of mapping you can do by tracing satellite imagery: hence “armchair mapping” #geowebchat

@mappingmashups Oct 06, 12:08pm I’d like to hear from those of you joining #geowebchat: who has done any remote mapping yourselves, for @TheMissingMaps or @hotosm perhaps?

@mappingmashups Oct 06, 12:10pm For #geowebchat on remote mapping, some provocative arguments challenging the idea: groundtruth.in/2015/06/05/osm… and place-memes.blogspot.de/2015/05/the-hu…

@AngharadStone Oct 06, 12:13pm @mappingmashups besides armchair mapping – are we also considering modelling mapping? Ie landslide or flood risk areas? #geowebchat

@mappingmashups Oct 06, 12:14pm @AngharadStone Interesting Q. Is there a way someone would do the modeling differently if they were on the scene vs remote? #geowebchat

@mappingmashups Oct 06, 12:16pm @AngharadStone armchair mapping is controversial for 2 reasons: 1) that remote ppl don’t know the situation on the ground… #geowebchat

@mappingmashups Oct 06, 12:16pm @AngharadStone …and 2) that remote mappers would displace or discourage local people from doing the mapping themselves #geowebchat

@mappingmashups Oct 06, 12:19pm @GeoCensos interesting article! Do you think that using local social media feeds is a way to get locals involved in mapping? #geowebchat

@AngharadStone Oct 06, 12:19pm @mappingmashups #geowebchat Do you have any evidence of remote mappers discouraging ground surveying?

@mapperz Oct 06, 12:20pm @AngharadStone @mappingmashups Flood Risk Mapping Polygons wrapped up with #geoserver #openlayers #geowebchat …od-warning-information.service.gov.uk/map #map

@ricaji Oct 06, 12:23pm It’s not necessarily a case of remote mappers discouraging. It’s more a case of too little support going to local mappers. #geowebchat

@mappingmashups Oct 06, 12:23pm @AngharadStone In the #OSM email thread there are many theories, but little evidence either way. lists.openstreetmap.org/pipermail/talk… #geowebchat

@mappingmashups Oct 06, 12:24pm Regarding #geowebchat, it looks like there’s a #missingmaps #mapathon happening in London as we speak! @inderpaldsingh @ukpwhite

@ricaji Oct 06, 12:26pm In some places can be tricky to create local ownership of the map as well and build local volunteer community.

@AngharadStone Oct 06, 12:26pm @mappingmashups #geowebchat Ok back to the main topic – do people consider the possible issues tracing aerial imagery? Eg tree cover

@mappingmashups Oct 06, 12:28pm @ricaji Maybe “discouraging” is the wrong word. It’s that remote mappers pre-empt a local map that would’ve evolved differently #geowebchat

@mappingmashups Oct 06, 12:29pm @AngharadStone Certainly that’s an issue. And in OSM there is also the frequent problem of misaligned or out-of-date imagery. #geowebchat

@TheMissingMaps Oct 06, 12:30pm @mappingmashups @inderpaldsingh @ukpwhite hi guys, remote mapping two areas of Congo tonight…. Big wave to #geowebchat gang!

@mappingmashups Oct 06, 12:30pm @AngharadStone Those are problems that even someone mapping a nearby town would face if they’re not skilled w/ aerial imagery #geowebchat

@mappingmashups Oct 06, 12:31pm @TheMissingMaps Which @hotosm tasks are you doing, out of curiosity? #geowebchat

@ricaji Oct 06, 12:32pm Remote mapping won’t ever be able to capture names which are of course key. So always needs to be combined with local knowledge. #geowebchat

@mappingmashups Oct 06, 12:32pm @AngharadStone Even if you are skilled w/ tree cover (for ex) remote mappers might interpret foreign buildings/paths/etc wrong #geowebchat

@mappingmashups Oct 06, 12:35pm @ricaji Yes! I’m curious about: is it easier to add names to existing roads? Or less fun? Too hard to see when they’re missing? #geowebchat

@neogeografen Oct 06, 12:38pm @mappingmashups We also have to fix the name problem – lots of ppl thinks OSM is a english project then lang=eng too @ricaji #geowebchat

@AngharadStone Oct 06, 12:39pm #geowebchat @ricaji @mappingmashups even on the ground naming is really hard to get right – we have several River Avon’s (= River river)

@ricaji Oct 06, 12:40pm It’s easier to add names, but, more fun to add the road IMO :) Of course, in contested spaces this is much more important. #geowebchat

@notoncebut2x Oct 06, 12:42pm @ricaji #geowebchat Yeah I am more likely to add buildings and features than attribute data in @openstreetmap especially if I am more remote

@ricaji Oct 06, 12:42pm (Of course it’s not that simple. @mapkibera had some initial tracing support to give some orientation to first mappers.) #geowebchat

@ricaji Oct 06, 12:43pm I think linking remote – local (people2people) is key also not getting stuck into a one size fits all process for each locale. #geowebchat

@ricaji Oct 06, 12:49pm For instance linking this local volunteer qub.me/IGB_2V to armchair folks opens up new opportunities… #geowebchat

@GeoCensos Oct 06, 1:00pm @ricaji Agree, and it builts up the vital need of “belonging to” a certain project and btw community #geowebchat

@mappingmashups Oct 06, 1:00pm Well, we’ve reached the end of our hour at #geowebchat (I had to duck out at the end there, sorry I couldn’t keep the conversation going)

@Zjwarie Oct 06, 1:00pm Just bumping on you interesting discussion! Here you have my opinion on the subject: openstreetmap.org/user/Jorieke%2… #geowebchat

@mappingmashups Oct 06, 1:01pm Thanks everybody for joining #geowebchat today. The transcript will be posted at mappingmashups.net soon. Feel free to keep chatting!

@mappingmashups Oct 06, 1:02pm Next #geowebchat will be in one month (Nov 3), same time. @GeoCensos will be our guest host to discuss open #geodata & national map orgs!

@ricaji Oct 06, 1:03pm @Zjwarie OK now summarize into a few tweets :) #geowebchat

#geowebchat transcript, 1 September 2015: #MapLift and @FixWikiMaps

@mappingmashups Sep 01, 8:50am Today (Tue Sep 1) on #geowebchat we’re talking about #MapLift (nacis.org/maplift/) & @fixwikimaps. Join us at noon PDT! Please RT!

@fixwikimaps Sep 01, 9:25am We’re going to be featured on @mappingmashups #geowebchat today, so be sure to tune in and ask questions! #MapLift

@mappingmashups Sep 01, 12:00pm Welcome everyone to our monthly #geowebchat twitter chat. Today we’re talking about @fixwikimaps and nacis.org/maplift/

@mappingmashups Sep 01, 12:01pm As always with #geowebchat, make sure you use the hashtag in your tweets to join the conversation. Or mute that hashtag to ignore us!

@fixwikimaps Sep 01, 12:01pm #geowebchat is live!

@mappingmashups Sep 01, 12:02pm I recommend using a tool like tweetchat.com/room/geowebchat to follow along more easily. For more about #geowebchat see: mappingmashups.net/geowebchat/

@mappingmashups Sep 01, 12:03pm So let’s start by explaining what @fixwikimaps and #maplift is all about. Then let’s do some show and tell & get feedback. #geowebchat

@mappingmashups Sep 01, 12:06pm @brianddavidson & @jscarto (& with me, a little bit) are the ones who run @fixwikimaps, an effort to improve maps on @Wikipedia #geowebchat

@mappingmashups Sep 01, 12:07pm @pinakographos & @NACIS joined in the effort with #maplift, which is a week-long @fixwikimaps marathon. It’s going on now! #geowebchat

@mappingmashups Sep 01, 12:08pm @jscarto @brianddavidson @pinakographos @NACIS @fixwikimaps Who of you all is joining #geowebchat? Want to tell us how #maplift is going?

@mappingmashups Sep 01, 12:09pm RT @tonyquartararo why not just convince @Wikipedia to use @openstreetmap @stamen @mapzen or @Mapbox as the standard references? #geowebchat

@fixwikimaps Sep 01, 12:09pm @mappingmashups #MapLift has been great so far! We’ve had over 100+ new maps added to our database and about 10 have been lifted!#geowebchat

@mappingmashups Sep 01, 12:10pm @tonyquartararo Good question! Mainly because most wiki articles need specific, custom maps, not just a default locator map. #geowebchat

@pinakographos Sep 01, 12:12pm @mappingmashups @jscarto @brianddavidson @NACIS @fixwikimaps Also I am so far failing to remember to type #geowebchat in my tweets.

@mappingmashups Sep 01, 12:12pm @tonyquartararo Although I recently learned @Wikipedia _does_ have a project to run its own OSM basemap #geowebchat mediawiki.org/wiki/Maps

@nixzusehen Sep 01, 12:12pm @tonyquartararo The default renderings aren’t appropriate for all articles. A good map enhances the article’s point. #geowebchat

@fixwikimaps Sep 01, 12:12pm @mappingmashups @tonyquartararo It is also monitored by the community, so Wikipedia doesn’t really put any limitations #geowebchat

@vtcraghead Sep 01, 12:12pm @mappingmashups @tonyquartararo Definitely seems like a reasonable approach for SOME article types to standardize maps. #geowebchat

@mappingmashups Sep 01, 12:13pm @tonyquartararo Well @mapisart is great for what it does: somewhat customized printed maps, but they’re not really encyclopedic #geowebchat

@pinakographos Sep 01, 12:14pm @mappingmashups @tonyquartararo Also, many articles need maps of historical regions/phenomenon, which web maps don’t have #geowebchat

@mappingmashups Sep 01, 12:14pm @tonyquartararo The kinds of maps that an encyclopedia article needs are like those listed on fixwikimaps.tumblr.com But better! #geowebchat

@mappingmashups Sep 01, 12:19pm Also, @pinakographos & @NACIS, what’s this I hear about a #MapLift show and tell on CartoTalk.com tomorrow? #geowebchat

@pinakographos Sep 01, 12:21pm @mappingmashups @NACIS We’re encouraging people to share their in-progress maps on CartoTalk.com tomorrow & Friday #geowebchat.

@pinakographos Sep 01, 12:21pm @mappingmashups @NACIS We’ve got some early discussion already going: cartotalk.com/index.php?show… #geowebchat

@mappingmashups Sep 01, 12:23pm Oh, & we didn’t mention about #maplift there will be prizes for the best maps created during the project! nacis.org/maplift/ #geowebchat

@mappingmashups Sep 01, 12:24pm So who is working on maps for @fixwikimaps and #MapLift? Does anyone want to share their work with #geowebchat? Anyone need advice?

@vtcraghead Sep 01, 12:24pm #MapLift has been an excellent reminder that static cartographer doesn’t come easily to me, needs workshopping. #geowebchat

@pinakographos Sep 01, 12:25pm @mappingmashups That’s close. Every map made is an entry into a prize drawing. more maps = more chances to win! #geowebchat

@vtcraghead Sep 01, 12:26pm Speaking of #maplift, this would be good to pair with the 1946 map here: en.wikipedia.org/wiki/Arctic_ic… #geowebchat

@fixwikimaps Sep 01, 12:27pm .@mappingmashups @vtcraghead We’ve been loving the step by step you’ve been doing on your #MapLift journey! #geowebchat

@pinakographos Sep 01, 12:27pm @mappingmashups @vtcraghead Seeing people share the stages of their work is great, and I don’t think it’s done enough #geowebchat

@mappingmashups Sep 01, 12:28pm If you’re working on #maplift, you can get feedback on CartoTalk: cartotalk.com/index.php?show… or on this Slack get.maptiks.com/gisdevs-on-sla… #geowebchat

@vtcraghead Sep 01, 12:29pm @pinakographos @mappingmashups Yeah, workshopping doesn’t come easily once we’ve adopted the label “professional”. #geowebchat

@mappingmashups Sep 01, 12:30pm @niperkm Good question for #geowebchat. Are there @fixwikimaps style guides we should follow? I’m sure there are @Wikipedia pages somewhere?

@pinakographos Sep 01, 12:32pm @mappingmashups @niperkm @fixwikimaps There’s en.wikipedia.org/wiki/Wikipedia…, but it seems to be deviated from often. #geowebchat

@pinakographos Sep 01, 12:33pm @mappingmashups @niperkm @fixwikimaps I think it’s useful more for people approaching this with 0 background skills #geowebchat

@fixwikimaps Sep 01, 12:34pm @mappingmashups @niperkm It looks like it’s only there for historical reference though #geowebchat

@mappingmashups Sep 01, 12:37pm RT @tonyquartararo: @pinakographos @mappingmashups good point. But a “way back machine” for OpenStreetMap ? #geowebchat

@mappingmashups Sep 01, 12:37pm @tonyquartararo @pinakographos Well, @OpenHistMap is the historical @openstreetmap spin-off project, but it has a long way to go #geowebchat

@pinakographos Sep 01, 12:38pm @tonyquartararo @mappingmashups That would be great and help in some situations, but still great value in custom, focused maps #geowebchat

@mappingmashups Sep 01, 12:38pm @gfred3rick We’re having a #geowebchat discussion about #maplift right now. Maybe someone will give you feedback there!

@fixwikimaps Sep 01, 12:39pm What do the folks on #geowebchat think?

@johnjcz Sep 01, 12:41pm Does there have to be any sort of consensus around maps that need fixing / fixed maps for #maplift? #geowebchat

@mappingmashups Sep 01, 12:46pm @johnjcz not really. Its admittedly very subjective. If a map needs help, you’ll know it when you see it! #maplift #geowebchat

@mappingmashups Sep 01, 12:50pm @johnjcz There’s a lot of maps on wikipedia that need help, so we don’t want to waste #maplift effort on “good enough” maps… #geowebchat

@mappingmashups Sep 01, 12:51pm RT @geo_will: sometimes you don’t know until you use it. Had a map for climbing in Pakistan, it was wrong, looked lovely though #geowebchat

@mappingmashups Sep 01, 12:52pm @geo_will Good point: most of #MapLift is about correcting style, not always fixing factual error #geowebchat

@pinakographos Sep 01, 12:53pm @johnjcz If the community disagrees, they might revert to the old map, which is fine. #geowebchat

@mappingmashups Sep 01, 12:53pm @geo_will this gets into the topic of “armchair mapping” which we mentioned in the last #geowebchat. And I think maybe next time’s topic.

@johnjcz Sep 01, 12:54pm @mappingmashups That’s why I was curious. Seems like most wikipedia maps are “good enough” ie factually correct but maybe “ugly” #geowebchat

@mappingmashups Sep 01, 12:55pm @johnjcz Well, “good enough” should also be a function of usability. If it’s factually correct but unreadable, it needs help. #geowebchat

@mappingmashups Sep 01, 1:00pm Thanks to everyone who joined today’s #geowebchat! Keep working on your #maplift projects, and check out nacis.org/maplift/ this week!

@johnjcz Sep 01, 1:02pm @mappingmashups Does @fixwikimaps have a “why” for maps that need fixing? Curious to see what people deem “not good enough” #geowebchat

@mappingmashups Sep 01, 1:03pm Next chat will be in one month: October 6th, same time. Topic will be “armchair mapping”! Mapping from the comfort of your home! #geowebchat

@mappingmashups Sep 01, 1:04pm @johnjcz @fixwikimaps fixwikimaps.tumblr.com tries to give a “why” about most of the maps that need fixing. #maplift #geowebchat

@AlbinPCLarsson Sep 01, 1:05pm .@fixwikimaps #maplift #geowebchat are you aware of the Commons map template?

Strongly recommend using it :-)

@mappingmashups Sep 01, 1:09pm @wildlifegisgirl I haven’t done any yet, but we just had a whole #geowebchat about #maplift! #gistribe

@mappingmashups Sep 01, 1:18pm @AlbinPCLarsson @fixwikimaps Is this the template you mean? commons.wikimedia.org/wiki/Template:… #geowebchat

#geowebchat transcript, 4 August 2015: outdoor mapping

@mappingmashups Aug 04, 12:00pm Welcome everyone to our monthly #geowebchat! Today we’re talking about “outdoor mapping”. Feel free to join the chat or just follow along!

@TheMissingMaps Aug 04, 12:00pm We’re not outdoor mapping, but here’s a wave for everyone on #GeoWebChat from #MissingMaps London https://pbs.twimg.com/media/CLliMmkWsAA5pq2.jpg

@mappingmashups Aug 04, 12:03pm So if you want to join the #geowebchat, just make sure to include that hashtag in all your tweets. Try tweetchat.com/room/geowebchat for following.

@mappingmashups Aug 04, 12:04pm So, I certainly had @openstreetmap in mind when I suggested this #geowebchat topic, but we can talk about any kind of outdoor mapping.

@mappingmashups Aug 04, 12:06pm The @OpenStreetMapUS #mapathon in spring was “great outdoors” themed. Did anyone join? What did you map? #geowebchat wiki.openstreetmap.org/wiki/Mapathon/…

@bethschechter Aug 04, 12:06pm Hey everyone! I’m really interested in hearing what kind of outdoor mapping activities people have done. #geowebchat

@bethschechter Aug 04, 12:07pm Did you use @fieldpapers? Did you learn orienteering? Were you using surveying tools? What was the purpose? #geowebchat

@bethschechter Aug 04, 12:08pm I want to know all the things! I’m also interested in maps about the great outdoors. #geowebchat

@mappingmashups Aug 04, 12:09pm @eleanortutt Did some people choose one tool and stick with it, or did everybody use a lot of those tools during the day? #geowebchat

@eleanortutt Aug 04, 12:10pm @mappingmashups I gave an intro listing those tools & a few more & people picked the one that suited them best. #geowebchat

@eleanortutt Aug 04, 12:12pm I like Field Papers b/c I can convert random people outdoors to mappers by handing them a map to mark up – no apps required #geowebchat

@mappingmashups Aug 04, 12:13pm @eleanortutt Did the mappers using @fieldpapers trace the maps themselves, or did other people do it? Curious about that with FP #geowebchat

@mappingmashups Aug 04, 12:14pm That’s also a question for the @TheMissingMaps mappers in London: are you tracing from @fieldpapers or from aerial imagery? #geowebchat

@eleanortutt Aug 04, 12:14pm @mappingmashups In this particular case, only one person used @fieldpapers & he traced himself. #geowebchat

@eleanortutt Aug 04, 12:15pm @mappingmashups But in the past, I’ve handed @fieldpapers to people & told them to just upload a photo whenever they are done. #geowebchat

@mappingmashups Aug 04, 12:18pm .@eleanortutt W/ tools like @fieldpapers & now @mapillary, sometimes the surveyor isn’t necessarily the one to add it to OSM. #geowebchat

@mappingmashups Aug 04, 12:19pm .@eleanortutt I guess that’s also true whenever you’re tracing from others’ GPS traces like w/ @Strava’s slide tool. #geowebchat

@npdoty Aug 04, 12:19pm @fieldpapers I want to use field papers to get a bunch of neighbors to map the locations of all the trees in Oakland. #geowebchat

@eleanortutt Aug 04, 12:20pm Might also make sense to do outdoor mapping with @fieldpapers in fall when weather is nice & then digitize indoors during winter #geowebchat

@ER1CK5ON Aug 04, 12:20pm #geowebchat How I am expermenting with outdoor mapping: mapillary.com/map/im/44QY4Kj…

@mappingmashups Aug 04, 12:21pm @npdoty @fieldpapers & species too, & maybe even approx height? You can sometimes map trees from aerial, but not much metadata #geowebchat

@TheMapSmith Aug 04, 12:22pm No channel for outdoor mapping (yet), but theres lotsa geo-convos happening @ The Spatial Community Slack thespatialcommunity.com #geowebchat

@mappingmashups Aug 04, 12:23pm @ER1CK5ON Are you walking or biking in that @mapillary photo? #geowebchat I’ve wondered abt improvising a kind of @mapillary walking vest

@BobGradeck Aug 04, 12:23pm #geowebchat favorite time to map trails is during winter. Easy to see tracks in snow, and no leaves makes for a better GPS signal.

@eleanortutt Aug 04, 12:26pm @BobGradeck But…cold! Rather be inside w/ hot cocoa. Side note: snow (tracks/lack thereof) also helps w/ vacant bldg surveys #geowebchat

@pcrickard Aug 04, 12:26pm There is a #geowebchat now. @Ellevatory

@mappingmashups Aug 04, 12:26pm RT @npdoty: yeah, I’ve been marking height and diameter (with standardized tags); species would be good for health research #geowebchat

@eleanortutt Aug 04, 12:29pm @mappingmashups @npdoty I learned some munis have staff arborists – worth checking & involving them if they exist where you are. #geowebchat

@mappingmashups Aug 04, 12:30pm @ER1CK5ON @mapillary The action cam is to steady the shots? I can see that, too much bounce, huh? #geowebchat

@mappingmashups Aug 04, 12:31pm @eleanortutt @npdoty Also worth checking, is there an #Oakland equivalent of @SFUrbanForester? #geowebchat #trees #SF

@bethschechter Aug 04, 12:33pm does anyone have experience with using a geo data collection app that collects both the path your on + easy point collection? #geowebchat

@bethschechter Aug 04, 12:34pm I’m thinking of the use case of bike mapping. You want to be collecting your path, and then easily switch to adding a point. #geowebchat

@ER1CK5ON Aug 04, 12:34pm #geowebchat I started down the same path ;-) and discovered this: bit.ly/1TEDqIZ and this amzn.to/1IWdWnO

@bethschechter Aug 04, 12:35pm @calimapnerd @calimapnerd cool. i had some trouble using it, but that was years ago. I should try again :) #geowebchat

@ER1CK5ON Aug 04, 12:36pm @mappingmashups @mapillary I dont know yet, have to get out and test it #geowebchat

@TheMapSmith Aug 04, 12:37pm We’ve used ArcGIS Collector with great success over the last few summers to collect field data. Very easy to setup, easy to use. #geowebchat

@ER1CK5ON Aug 04, 12:37pm @BobGradeck good point, fall and early spring good time here in VA too! #geowebchat

@eleanortutt Aug 04, 12:38pm Good to know. Still searching for perfect app. Mentioned OSMAnd at mapathon but haven’t personally used. #geowebchat

@mappingmashups Aug 04, 12:39pm @bethschechter I think a lot of bike mappers use a voice recorder and then transcribe their notes later using gps + timestamp #geowebchat

@ER1CK5ON Aug 04, 12:40pm @bethschechter my old garmin edge 305 allowed POI collection by hitting a button. It has to have improved since that version #geowebchat

@mappingmashups Aug 04, 12:41pm Anyone have experience doing outdoor OSM mapping w/ a group & dividing up territory? Curious about this: wiki.openstreetmap.org/wiki/MapCraft #geowebchat

@bethschechter Aug 04, 12:41pm nice! thanks for the advice y’all #geowebchat

@talldave Aug 04, 12:44pm @mappingmashups Shawn Britton does a lot of that meetup.com/Bay-Area-OpenS… #geowebchat

@Ellevatory Aug 04, 12:46pm Thanks, what is the topic of #geowebchat?

@mappingmashups Aug 04, 12:46pm Is MapCraft the best (or only) tool for making Cake Diagrams? Do most mappers do them by hand or w/ GIS? #geowebchat

@mappingmashups Aug 04, 12:47pm @Ellevatory @pcrickard We’re talking about outdoor mapping today. #geowebchat

@neogeografen Aug 04, 12:48pm On bike – Mapillary fits for easy&quick collect. surface=XX, lit=yes/no and barrier=cycle_barrier and finding new paths #geowebchat

@mappingmashups Aug 04, 12:49pm What tools do you wish existed for easier outdoor mapping? What’s missing? How can we make it more effective and fun? #geowebchat

@tim_waters Aug 04, 12:51pm @mappingmashups print out a map, meet mappers, draw on the map. Much easier and interactive and you get to chat with the mappers #geowebchat

@Ellevatory Aug 04, 12:52pm Yo #geowebchat, I’m a regular over at #gistribe, what is your hashtag all about and does it reoccur e.g. weekly?

@mappingmashups Aug 04, 12:53pm @Ellevatory #geowebchat is monthly on the 1st Tuesday. More info here (plus transcripts) mappingmashups.net/geowebchat/

@Ellevatory Aug 04, 12:53pm This stuff looks really cool – 3D augmented reality map – youtube.com/watch?v=CE1B7t… #geowebchat

@ER1CK5ON Aug 04, 12:55pm @mappingmashups AFFORDABLE GPS Cameras with GPS Voice Tagging, Sunlight Readable Display, Endless Nice Weather??#geowebchat

@Ellevatory Aug 04, 12:55pm Thanks mate! #geowebchat

@bethschechter Aug 04, 12:56pm @Ellevatory that is totally one of the coolest uses of AR I’ve seen! The @exploratorium should get one of those :) #geowebchat

@skorasaurus Aug 04, 12:56pm for outdoor mapping, I use voice recording w/ osmtracker, + @mapillary although my s5′s camera focus results in blurry photos #geowebchat

@eleanortutt Aug 04, 12:57pm @mappingmashups Random thought: would be cool to get notification when I’m near another mapper – maybe my OSM “friends” #geowebchat

@mappingmashups Aug 04, 12:57pm Any last thoughts about outdoor mapping for this #geowebchat? Maybe next chat should be about the opposite: armchair mapping?

@eleanortutt Aug 04, 12:58pm @mappingmashups Although maybe by cool I mean creepy – it would depend on my mood. But might help coordinate mapathons. #geowebchat

@ColinReillyNY Aug 04, 12:58pm @mappingmashups for trees there’s @TreeKIT being used by @NYCParks for TreesCount nycgovparks.org/trees/treescou… #geowebchat

@KubaKonczyk Aug 04, 12:59pm @Ellevatory it’s also quite easy to build using old kinect:D #geowebchat

@mappingmashups Aug 04, 12:59pm @eleanortutt That would be cool. OSM definitely needs more enhanced social features. See: brainoff.com/weblog/2012/03… from @mikel #geowebchat

@eleanortutt Aug 04, 12:59pm @mappingmashups Would also be helpful to easily add custom CartoCSS styles to @fieldpapers basemaps #geowebchat

@mappingmashups Aug 04, 1:00pm Thanks all for joining this #geowebchat! Next one will be same time on September 1st. As always I’m seeking guest hosts & topic suggestions!

@MAPTIMELA Aug 04, 1:00pm @mappingmashups I @machikoyasuda want to map trails w/ POC/Native stories like pri.org/stories/2014-1… foresthistory.org/ASPNET/People/… #geowebchat

@mappingmashups Aug 04, 1:00pm The transcript for this #geowebchat about outdoor mapping will be posted at mappingmashups.net/geowebchat in a few days

@eleanortutt Aug 04, 1:01pm @mappingmashups Thanks for hosting! #geowebchat

@bethschechter Aug 04, 1:01pm @tvargs no idea! I should look it up though :) #geowebchat thanks for the lead!

@ER1CK5ON Aug 04, 1:02pm Future topic? Unmapped trails, getting them in OSM!!#geowebchat

@bethschechter Aug 04, 1:02pm @mappingmashups thanks for putting this together! So helpful! #geowebchat

@Ellevatory Aug 04, 1:06pm Since the topic is outdoor mapping, it makes me I wonder what kind of mapping is not done outdoor? #geowebchat

@mappingmashups Aug 04, 1:11pm @Ellevatory There’s a concept in #openstreetmap called “armchair mapping” which isn’t done outdoors wiki.openstreetmap.org/wiki/Armchair_… #geowebchat

@Ellevatory Aug 04, 1:19pm Interesting @mappingmashups I did not know of this until Nepal earthquake, it puzzled me ppl mapped but hadn’t been there #geowebchat

Year two at Stamen

As you may have noticed, I’m not really using this blog as a blog anymore. All my recent blog posts are geowebchat transcripts. If you want to read my occasional blog posts that are not twitter transcripts, I’ve tagged those with “not_geowebchat” for your convenience.

I don’t have time to write blog posts anymore. And today is no different, so I’ll make this short. But I thought I should write something. Apologies if this post reads more like a grab-bag of links and screenshots (FYI, all images are clickable links). For a more structured post, maybe check out my interview at the Geohipster blog.

new map stencil

Last week I hit the two year mark at Stamen Design. (No, I didn’t write a blog post at year one). Those two years have flown past, and this continues to be the most amazing job I’ve ever had. So, what have I been up to?

At Stamen we do data visualization and custom cartography. Clients hire us when they need help understanding some complex dataset, or when they need to communicate data to the public in ways that are compelling, insightful, and beautiful at the same time. I get to explore and process all kinds of geographic data, write code to turn this data into interactive maps, and work with designers to figure out what the maps should look like. Every dataset is unique, and every client’s needs are different; it’s an endless stream of new and exciting puzzles to figure out.

One of my favorite recent examples is our visualization of the impact of climate change on bird migration for the Audubon society. Their scientists used climate models to predict the future migration ranges for hundreds of North American bird species. We took their data and made shareable animated maps that showed how much range these birds would lose and (potentially) gain.


At Stamen we use open data and open source tools to make these visualizations, so I also spend a lot of time working on the basemaps that underly many of our projects, for example updating Stamen’s distinctive “Toner” style.


We also designed brand-new basemaps for CartoDB, an online visualization tool which lets anybody make their own data-rich maps:


Those were just a few of the projects I worked on. Here are a few more: mapping methane leaks for the EDF, a map of ocean protected areas in the US and Canada, mapping the arts landscape in Detroit, visualizing urban water resources around the world.

Many others weren’t public, or haven’t been made public yet. In other cases my contribution is mainly behind the scenes. One of my other favorite Stamen challenges was collecting social media activity to feed into our CaliParks.org website. The algorithms we developed to harvest the social media resulted in some fascinating geographic patterns, but none of these maps made sense to include in the user-facing app.

Screen Shot 2015-07-12 at 12 Jul 6.24.07

With every project there are opportunities to explore, experiment, and create glitches that test the limits of our tools and our designs. These are some of the most interesting outcomes of the Stamen process, and frequently the most fun.


Often it’s possible to make beautiful new maps by building on the work of others, remixing existing maps and tools with a couple of lines of code:


All of these projects involve collaborating closely with a team of brilliant colleagues at Stamen. None of our projects are solo endeavors, and working with great people is one of the special pleasures of being at Stamen. The teams are small, but the list of colleagues is a bit too long to list here. There’s also a lot of pride in carrying on the Stamen reputation established by all the Stamen alumni before us. Some of them I still haven’t met, but nonetheless it feels like we’ve all been working together (just separated a bit in space and time) to build something special and lasting.

When it comes to amazing people I’ve worked with, I do want to mention by name Zach Watson, who we lost tragically and unexpectedly last year. Many other people were much closer to him than I was, but I got to work beside him for my first year at Stamen and learned a lot from him. It’s a small consolation that Stamen helped found the Zachary Watson Memorial Education Fund in his memory.

Teaching and speaking

We are very lucky and privileged to do what we get to do at Stamen, and I’m glad that education and knowledge sharing is a core principle of what we’re all about. In the last two years I’ve co-taught a couple of classes about web mapping at Parisoma, and given guest lectures all across the Bay Area: explaining OpenStreetMap to cartography students at SFSU, talking about digital mapping and the city to Urban Studies students at USF and designers at the Stanford D-School, speaking to art students at UC Berkeley, running a mapping workshop at CCA, and a teaching workshop for the UC Curriculum Institute. Many of those presentations were in conjunction with my education-and-outreach partner-in-crime Beth Schechter. A bit further afield down in L.A., I also gave a talk to design students with Jon Christensen at Cal Poly Pomona.

This is all in addition to the usual conference attending: Association of American Geographers, State of the Map [1] [2] [3], NACIS, FOSS4G [1] [2], and a few that that I haven’t attended before, like DataEDGE and the Computer Supported Collaborative Work (CSCW) conference. Closer to home, I also gave a brown bag research talk at the Wikimedia Foundation in San Francisco.

So, it’s clear that education and outreach is important at Stamen, and this includes hosting OpenStreetMap editathons in the studio once in a while.


Of course one of the biggest educational projects I’ve been lucky enough to be involved with is Maptime, which was just getting started by Beth Schechter and Camille Teicheira right at the same time I started at Stamen. Maptime is a grassroots, beginner-focussed series of mapping meetups that quickly grew well beyond its humble beginnings at Stamen. This was due in no small part to the energy and enthusiasm of Lyzi Diamond who joined as an organizer not long after Maptime’s founding. There are now Maptime chapters in cities all over the world, and it’s been fun to visit a few of them in Vancouver and Chicago on my travels. A lot has been said about Maptime elsewhere (like, for example, from Lyzi herself), so I won’t say much more here. After two years of helping to coordinate Maptime’s growth, and after giving a co-keynote with Beth, Camille, and Lyzi at the CalGIS conference, and after we organized our first Maptime Summit in NYC, I’m starting to ramp down my involvement with Maptime, assured that it’s in very good hands. I’ll still be involved on the Maptime HQ Board of Directors as we go through the process of getting nonprofit status.

The dissertation

Yes, I am also still working on my PhD dissertation at the University of British Columbia. Yes, I will finish it someday. I need to thank my dissertation committee for their patience and indulgence, and also thanks to Stamen for helping me find time here and there to keep making progress. Anyhow, ask me about it some other time.


While I’ve been at Stamen, my dissertation research has had some interesting spin-offs, like the map above which shows every line that ever existed in the OpenStreetMap database. This map won first place in the See-Through Maps exhibit which was part of the Mapping and its Discontents symposium at UC Berkeley. We later showed a version of the map at the Istanbul Design Biennial and I included it in an article I wrote about OpenStreetMap for SPUR’s magazine The Urbanist.


What’s in store the next two years? Plenty of exciting new Stamen projects are in the works, and who knows what other new projects will come through the door that we haven’t even imagined yet. Stay tuned to the Stamen blog, and follow me on Twitter, Flickr, and Pinterest for more frequent updates and teasers like this one:

@jeresuikkila Jul 07, 11:48am Knock, knock!

Who’s there?


…, who?

Not who! “Where”!

@erictheise Jul 07, 11:48am will you be dropping by the #geowebchat today, @nixzusehen? it’s about #geocoding and it starts at noon, pacific. twelve minutes from now!

@riordan Jul 07, 11:56am @erictheise You think I’d miss #geowebchat?!

@erictheise Jul 07, 11:58am never doubted for a moment, @riordan. you didn’t miss #geobreakfast east and, come to think of it, neither did @nixzusehen. #geowebchat

@mappingmashups Jul 07, 12:00pm Starting now: our monthly #geowebchat twitter chat! Today’s topic is #geocoding with guest hosts @philiphubs and @jeresuikkila from @here!

@philiphubs Jul 07, 12:01pm Hello and welcome to the #geowebchat – Today it’s about geocoding!

@mappingmashups Jul 07, 12:01pm As always, if you want to join #geowebchat, make sure to include the hashtag in your tweets. If you want to ignore us, just mute the tag.

@mappingmashups Jul 07, 12:01pm Tools like @TweetChat tweetchat.com/room/geowebchat are a good way to follow along with #geowebchat.

@philiphubs Jul 07, 12:02pm Thanks @mappingmashups. My name is Philip and I work at @here as a Product Manager for our Geocoder API. Who is with us today? #geowebchat

@mappingmashups Jul 07, 12:02pm And now, without further ado, let me hand things over to @philiphubs, our guest #geocoding expert! #geowebchat

@OpenCageData Jul 07, 12:02pm alright #geowebchat #geocoding we’re here, looking forward to your questions

@OpenCageData Jul 07, 12:03pm and by here I of course mean 41.3966,2.1988 #geowebchat #geocoding

@mappingmashups Jul 07, 12:04pm @OpenCageData Hah, you already want to talk about #reversegeocoding? :) #geowebchat

@riordan Jul 07, 12:05pm @philiphubs Greetings from the @mapzen Pelias geocoder team. I wonder what today’s geocoder builder to user ratio’s going to be? #geowebchat

@philiphubs Jul 07, 12:05pm @OpenCageData Hola and welcome! Who else do we have? #geowebchat

@JessiBreen Jul 07, 12:05pm Lurking. #geowebchat

@philiphubs Jul 07, 12:06pm @riordan @mapzen Right, you are taking away my first question :) #geowebchat

@Innisfree Jul 07, 12:06pm @JessiBreen I’m lurking too. #geowebchat.

@ChrisSheldrick2 Jul 07, 12:06pm @philiphubs @mappingmashups @here I’m here from @what3words look forward to chatting #geowebchat

@mappingmashups Jul 07, 12:07pm @riordan, good question. I’m definitely more of a geocoder user than a builder. #geowebchat Although I try to avoid geocoding when I can..

@philiphubs Jul 07, 12:07pm So let’s start: Are you a user or a creator of geocoding? #geowebchat

@blackmad Jul 07, 12:07pm @riordan @philiphubs @mapzen might be here. #geowebchat

@JessiBreen Jul 07, 12:08pm Occasional user. #geowebchat

@OpenCageData Jul 07, 12:08pm @ChrisSheldrick2 @philiphubs @mappingmashups @here @what3words Hi Chris, I’m on the keyboard at w3w.co/earliest.saint… #geowebchat

@erictheise Jul 07, 12:08pm i’m a geocode consumer. application developer, sometime cartographer. #geowebchat

@riordan Jul 07, 12:08pm @blackmad This #geowebchat was kinda made for you.

@OpenCageData Jul 07, 12:09pm @mappingmashups the rise of mobiles means reverse is now the most common type of geocoding #geowebchat

@Innisfree Jul 07, 12:09pm User – social science research requires geocoding these days. #geowebchat

@mappingmashups Jul 07, 12:10pm @OpenCageData Maybe we should define #geocoding and reverse geocoding? #geowebchat

@riordan Jul 07, 12:10pm @philiphubs I’m a lot of both. I just joined the Mapzen Pelias team (a little over 2 weeks ago) #geowebchat (1/2)

@erictheise Jul 07, 12:10pm i’ve tried many of free(ish) and open(ish) ones, installed Tiger Geocoder into my postgis, broken terms of service, i confess. #geowebchat

@philiphubs Jul 07, 12:11pm @OpenCageData @mappingmashups Yes, reverse geocoding is rising in usage from mobile. What is your share? Forward vs. reverse #geowebchat

@OpenCageData Jul 07, 12:12pm @philiphubs @mappingmashups #geowebchat hmm, just realized I don’t have recent numbers, but reverse is on the rise.

@riordan Jul 07, 12:12pm @OpenCageData Exactly. It’s why Factual’s orienting their product around their reverse geocoder. #geowebchat

@philiphubs Jul 07, 12:12pm Geocoding is the ability to match addresses to the correct location (latitude and longitude) on a map. Do you agree? #geowebchat

@blackmad Jul 07, 12:13pm Writer of twofishes.net coarse geocoder, ex-google geocoder, seeker/cosnumer of street level geocoding APIs #geowebchat

@riordan Jul 07, 12:13pm @philiphubs Worked on historical geocoders back @nypl_labs, & search places in 4SQ, Google, Apple Maps every day #geowebchat (2/2)

@OpenCageData Jul 07, 12:13pm @philiphubs @mappingmashups #geowebchat common use case is app devs. phone tells them coords, they want to show humans an understandable loc

@mappingmashups Jul 07, 12:13pm Quick defn: #geocoding is taking an address (or descriptive location) and finding coordinates. Reverse is lat/lon -> address. #geowebchat

@philiphubs Jul 07, 12:13pm Reverse Geocoding gets the next street address or area information for the given geographic coordinate. #geowebchat

@riordan Jul 07, 12:14pm @OpenCageData @philiphubs @mappingmashups Translating an indecipherable addressing system into a semi-semantic one #geowebchat

@RebeccaSiGo Jul 07, 12:15pm I didn’t know there was a #geowebchat. How to serve breakfast through Twitter?

@OpenCageData Jul 07, 12:16pm @riordan @philiphubs @mappingmashups #geowebchat yes, hence why we’d love it if others help with this project github.com/OpenCageData/a…

@ChrisSheldrick2 Jul 07, 12:16pm We @what3words have a #geocoder & #reversegeocoder converting 3 word addresses <> coordinates. The 3 words are dictionary words. #geowebchat

@alogicalfallacy Jul 07, 12:16pm @JessiBreen Lurking club represent. Have spent many hours teaching reverse geocoding on mobile. Less so traditional. #geowebchat

@mappingmashups Jul 07, 12:17pm RT @SamuelLeach Geocoding is finding a boundary for an address. #geowebchat

@mappingmashups Jul 07, 12:18pm RT @ColinReillyNY @philiphubs @mappingmashups @here Hello from NYC DoITT developers of the Geoclient API #geowebchat

@dianashk Jul 07, 12:18pm more pelias people in the house. mostly geocoder builder. user when testing. #geowebchat

@philiphubs Jul 07, 12:18pm At @here the Geocoder API usage is 90% reverse, 10% forward. But forward geocoding is the more interesting problem to solve #geowebchat

@riordan Jul 07, 12:19pm @OpenCageData @philiphubs @mappingmashups Hear hear! This only works when we work together and hold hands. #geowebchat

@riordan Jul 07, 12:20pm For historical texts, geoparsing and forward geocoding has always been the use case, like what @schuyler did with Gutencarte #geowebchat

@vicchi Jul 07, 12:21pm @mappingmashups True. But the best geocoders are those that work with the way humans speak and that’s not always addresses #geowebchat

@riordan Jul 07, 12:21pm @OpenCageData We’re tremendously excited about the github.com/OpenCageData/a… and can’t wait to contribute. #geowebchat (1/2)

@riordan Jul 07, 12:21pm @OpenCageData This only works when we can empower people to bring local knowledge of the places they care about. Easily. #geowebchat (2/2)

@vicchi Jul 07, 12:21pm @mappingmashups Colloquial, vernacular and informal geographies are essential to good geocoding and geoparsing #geowebchat

@philiphubs Jul 07, 12:23pm @vicchi @mappingmashups Show us some examples Gary. I like how Colombia or Salt Lake City addresses work, e.g. 1700 E 1700 S #geowebchat

@jeresuikkila Jul 07, 12:23pm .@ChrisSheldrick2 @what3words we are tweeting from w3w.co/scarcely.path…. today. Otherwise known as Downtown Berkeley #geowebchat

@mappingmashups Jul 07, 12:24pm cc #geowebchat RT @SamuelLeach @ChrisSheldrick2 @mappingmashups Having the bounding box, or precise boundary useful for quantitative work.

@OpenCageData Jul 07, 12:24pm @riordan we’re all sitting anxiously refreshing the pull request page! #geowebchat

@OpenCageData Jul 07, 12:25pm @philiphubs @vicchi @mappingmashups #geowebchat A good example – if I say let’s meet for dinner in Chinatown you prob know what I mean 1/

@OpenCageData Jul 07, 12:26pm @philiphubs @vicchi @mappingmashups #geowebchat but in most cities that is not an “official” location 2/

@Innisfree Jul 07, 12:27pm Oregon is blank except for Portland. What’s up UO? @SVendetta86 @jblairpdx @map_chicago openaddresses.io #geowebchat

@riordan Jul 07, 12:27pm @OpenCageData @philiphubs @vicchi @mappingmashups Which comes back to incorporating colloquial geographies into our gazetteers #geowebchat

@mappingmashups Jul 07, 12:27pm @OpenCageData Or even if “Chinatown” is an official location, people might perceive its boundaries differently from the city. #geowebchat

@philiphubs Jul 07, 12:27pm @OpenCageData @vicchi @mappingmashups Neighborhood names are definetly one input to geocoding #geowebchat

@mapzen Jul 07, 12:28pm tune into #geowebchat for a fascinating discussion about geocoding (and reverse geocoding!)

@juliansimioni Jul 07, 12:28pm @philiphubs @vicchi @mappingmashups I think the idea is no one thinks “Im at 1600 Pennsylvania av”, just “im at the white house” #geowebchat

@erictheise Jul 07, 12:28pm always find way in grid-addressed city @philiphubs–i’m from chicago–but isn’t navigating a new orleans better for the brain? #geowebchat

@ChrisSheldrick2 Jul 07, 12:28pm @jeresuikkila Great location. That’s one spacious car park. Not to be confused with the lovely scarcely.path.land #geowebchat

@riordan Jul 07, 12:29pm @mappingmashups @OpenCageData Here in New York we have 3 “Chinatown”‘s. It’s a hard disambiguation #geowebchat

@philiphubs Jul 07, 12:30pm @OpenCageData @vicchi @mappingmashups General Zao Chicken anyone? *gettinghungry* #geowebchat

@dianashk Jul 07, 12:31pm if you make geocoders, how do you test it? if you use them, how do compare/evaluate available options? #geowebchat

@vicchi Jul 07, 12:31pm @OpenCageData @philiphubs @mappingmashups And let’s not forget places which don’t have an address because they don’t exist #geowebchat

@vicchi Jul 07, 12:32pm @OpenCageData @philiphubs @mappingmashups Not fictitious places but territories which just don’t have formal addressing ##geowebchat

@mappingmashups Jul 07, 12:33pm @ChrisSheldrick2 @jeresuikkila I find that confusing w/ @what3words: w3w.co/scarcely.path…. isn’t near scarcely.path.land #geowebchat

@ChrisSheldrick2 Jul 07, 12:33pm @riordan @OpenCageData Great point on ambiguity. Ambiguity was something we strived to eliminate when creating @what3words #geowebchat

@philiphubs Jul 07, 12:33pm @dianashk We have a huge test data set we run every night to ensure we don’t break anything while coding. #geowebchat

@mappingmashups Jul 07, 12:34pm @ChrisSheldrick2 @jeresuikkila And I’m at w3w.co/defeat.labels…. but my coworker at the next desk is quench.nature.tribe #geowebchat

@alogicalfallacy Jul 07, 12:35pm I’d be curious to hear @R_RoseRedwood thoughts on geocoding ambiguity given his work on street numbering, modernity, etc. #geowebchat

@ChrisSheldrick2 Jul 07, 12:35pm @mappingmashups @jeresuikkila @what3words Is it more or less confusing/error prone than if both were in the same city? #geowebchat

@philiphubs Jul 07, 12:35pm Is your input for geocoding typically an address, partial address, place name, a combination of all? #geowebchat

@riordan Jul 07, 12:35pm @philiphubs @dianashk Which raises another question: how to disambiguate issues in the (ever-changing) data from issues in code? #geowebchat

@juliansimioni Jul 07, 12:35pm @philiphubs how did you build up that dataset? from user querys? manually? how do you decide what your geocoder “should” return? #geowebchat

@vicchi Jul 07, 12:36pm @OpenCageData @philiphubs @mappingmashups Oh & places which officialdom doesn’t recognise – favelas, slums, shanty towns #geowebchat

@mappingmashups Jul 07, 12:36pm RT @dianashk we’re working on same sort of thing, but trying to make a communal data set for general purpose geocoder testing. #geowebchat

@philiphubs Jul 07, 12:36pm @riordan @dianashk By doing daily tests we can seperate code changes from data changes. #geowebchat

@vicchi Jul 07, 12:37pm @mappingmashups @SamuelLeach @ChrisSheldrick2 Polygons need geocoding love too and make life easier but are buggers to source #geowebchat

@mappingmashups Jul 07, 12:38pm @jeresuikkila @ChrisSheldrick2 Good point. @what3words makes a reasonable tradeoff to be more error-resistant #geowebchat

@erictheise Jul 07, 12:38pm throwing this on the heap: any thoughts on @richardf’s @sotmus mention of app where you could walk & say addresses into #osm? #geowebchat

@philiphubs Jul 07, 12:38pm @juliansimioni It’s both, a combination of real user queries and “ground truth” data we collected. QA is so important!! #geowebchat

@riordan Jul 07, 12:39pm @erictheise @richardf @sotmus Audio narration over gps trace is apparently already part of the JOSM workflow (?!). So yeah. #geowebchat

@erictheise Jul 07, 12:40pm (would have to watch @richardf’s talk video or dig out notes, can’t easily find a repo for or mention of that of which i speak) #geowebchat

@philiphubs Jul 07, 12:40pm @vicchi @mappingmashups @SamuelLeach @ChrisSheldrick2 Do you mean admin boundaries, cartos, and the like? #geowebchat

@erictheise Jul 07, 12:40pm o, @riordan nails it, thanks! #geowebchat

@ColinReillyNY Jul 07, 12:40pm Proliferation of alias/vanity addresses in NYC is a real problem for us. How do other cities handle? #geowebchat

@vicchi Jul 07, 12:41pm @riordan Careful, once you get @tim_waters started on psychogeography it’s a wild ride but a good one! #geowebchat

@mappingmashups Jul 07, 12:41pm cc #geowebchat RT @dianashk probably one of the most critical things in this space! what are your thoughts on a single public data set?

@vicchi Jul 07, 12:42pm @philiphubs @mappingmashups @SamuelLeach @ChrisSheldrick2 Precisely! But there is no one true map beyond admins #geowebchat

@philiphubs Jul 07, 12:42pm @ColinReillyNY Oh, these are common across the globe. Some countries have different names in different languages for same street #geowebchat

@OpenCageData Jul 07, 12:43pm @riordan @philiphubs @vicchi @mappingmashups #geowebchat any country in particular you’re targeting? Try geocoding India #mypredicitonpain

@vicchi Jul 07, 12:44pm @OpenCageData @riordan @philiphubs @mappingmashups Think globally! It’s the only way on the interwebs these days #geowebchat

@philiphubs Jul 07, 12:45pm @ColinReillyNY This is why we have a “normalize names” feature in HERE Geocoder and keep many alternative names in our map data #geowebchat

@dianashk Jul 07, 12:46pm #geowebchat @philiphubs would love to know that as well. we’re trying to cover all the basis by working on NLP as well as address parsing.

@freyfogle Jul 07, 12:46pm @riordan @philiphubs @vicchi @mappingmashups #geowebchat here’s a talk I gave re: our Indian efforts at @nestoria slideshare.net/lokku/geocodin…

@philiphubs Jul 07, 12:49pm @dianashk There are various paths. Some do a sort of auto-correction before the index match, others prefer fuzzy matching #geowebchat

@ColinReillyNY Jul 07, 12:49pm @dianashk @philiphubs All above + intersection + blockface #geowebchat

@riordan Jul 07, 12:50pm Attn geo users: There’s a fabulous tool in @freyfogle’s slides to compare (forward geocoding) services gisgraphy.com/compare/ #geowebchat

@vicchi Jul 07, 12:50pm @jeresuikkila @OpenCageData @riordan @philiphubs @mappingmashups That’s a whole other #canofworms #geowebchat

@freyfogle Jul 07, 12:52pm @riordan #geowebchat unfortunately I’m not certain that tool is maintained. The copyright on the page leads me to believe it isn’t

@jeresuikkila Jul 07, 12:53pm @riordan @freyfogle interesting results for that “chinatown” mentioned earlier #geowebchat

@Innisfree Jul 07, 12:53pm RT @riordan Tool for comparing geocoding results. Thanks @freyfogle! gisgraphy.com/compare/ #geowebchat

@mappingmashups Jul 07, 12:53pm cc #geowebchat RT @riordan: @vicchi @jeresuikkila @OpenCageData @philiphubs @mappingmashups Don’t get me started on Swatch Beats Time

@philiphubs Jul 07, 12:55pm @riordan @vicchi @jeresuikkila @OpenCageData @mappingmashups I had one of those! #confessions #geowebchat

@harizh Jul 07, 12:55pm @riordan @freyfogle how do we get a new geocoding service (such as pelias) into gisgraphy? #geowebchat

@philiphubs Jul 07, 12:56pm Time is nearly up: What do you see needs improvement to make geocoding better? #geowebchat

@vicchi Jul 07, 12:56pm @mappingmashups @riordan @OpenCageData @philiphubs You need to open a can of worms to get data sets essential for geocoding #geowebchat

@OpenCageData Jul 07, 12:56pm @vicchi @mappingmashups @riordan @philiphubs do NOT say licensing, do NOT say licensing, do NOT say licensing #geowebchat

@vicchi Jul 07, 12:56pm @OpenCageData @mappingmashups @riordan @philiphubs Licensing. Licensing. Licensing. Don’t dodge the issue. It’s not going away #geowebchat

@freyfogle Jul 07, 12:57pm @harizh @riordan #geowebchat Not a clue. I am just a user, not the maintainer.

@mappingmashups Jul 07, 12:57pm @vicchi @OpenCageData @riordan @philiphubs Appropriately, we had a #geowebchat about geodata licenses back in Feb: mappingmashups.net/2015/02/03/geo…

@dianashk Jul 07, 12:58pm @ColinReillyNY @philiphubs intersections are really interesting. wonder how important they are globaly. #geowebchat

@iandees Jul 07, 12:58pm Hey #geowebchat, not enough pull requests being opened for github.com/openaddresses/…. Share the data you’ve found!

@riordan Jul 07, 12:59pm @dianashk @ColinReillyNY @philiphubs Intersections is apparently “a thing”. It’s in Google, not in Nominatim. #geowebchat

@mappingmashups Jul 07, 12:59pm Thanks to @philiphubs for hosting today’s #geowebchat! We’ve reached the end of our hour, but everyone feel free to keep chatting.

@riordan Jul 07, 1:00pm Seconded. Get in on @openaddresses. Help make it better! #geowebchat

@philiphubs Jul 07, 1:00pm @riordan @dianashk @ColinReillyNY Oh yes, for HERE Geocoder we have customers doing nothing but intersection geocoding #geowebchat

@ColinReillyNY Jul 07, 1:00pm @riordan @dianashk @philiphubs It’s in Geoclient as well. Represents over 10% of all NYC 311 geocodes. #geowebchat

@mappingmashups Jul 07, 1:00pm I’ll post the transcript of today’s #geowebchat shortly at mappingmashups.net/geowebchat. Next chat will be the same time, on August 4th. Topic TBD

@philiphubs Jul 07, 1:02pm @dianashk @ColinReillyNY This is why HERE Geocoder also offer the output for cross streets with house no. results #geowebchat

@dianashk Jul 07, 1:03pm @philiphubs NLP will be the next leap in geocoding. as others mentioned, understanding the way people talk about locations #geowebchat

@riordan Jul 07, 1:03pm @philiphubs Ultimately, better open data improves geocoding. We can raise the global baseline; lower everyone’s costs. #geowebchat

@harizh Jul 07, 1:03pm @philiphubs @riordan @dianashk @ColinReillyNY how do you guys do intersections? at the time of data import or at query time? #geowebchat

@philiphubs Jul 07, 1:04pm Thanks @mappingmashups for this #geowebchat it was great! Thanks to all the participants. For those in the Bay Area, love to meet in person!

@jeresuikkila Jul 07, 1:04pm @dianashk @philiphubs “meet me at the bottom of the stairs of the big white church” always worked for foreigners in Helsinki #geowebchat

@juliansimioni Jul 07, 1:04pm @philiphubs outreach towards orgs with data. there are so many govs with data that could help us if we could just get to it #geowebchat

@riordan Jul 07, 1:00pm Seconded. Get in on @openaddresses. Help make it better! #geowebchat twitter.com/iandees/status…

@philiphubs Jul 07, 1:06pm @harizh @riordan @dianashk @ColinReillyNY We offer both. Put both names in input or in separate fields. #geowebchat

@juliansimioni Jul 07, 1:06pm @philiphubs imagine all the tiny geo teams in muni govs that just need to be helped a bit and could easily open their data #geowebchat

@ColinReillyNY Jul 07, 1:06pm @harizh @philiphubs @riordan @dianashk we process the data on import. #geowebchat the chat that wont end…

@erictheise Jul 07, 1:08pm get on down to a #geobreakfast, @philiphubs, fridays, 8:30-10a, #PorkStoreCafe16thSt across from the Roxie Theater. #geowebchat

@philiphubs Jul 07, 1:08pm @juliansimioni I totally agree! Sourcing data is one of the biggest cost drivers for us at HERE too. We have over 80k sources #geowebchat

@vicchi Jul 07, 1:08pm @mappingmashups Thanks Alan; as always #geowebchat was geotastic!

@philiphubs Jul 07, 1:09pm @erictheise Thanks!! #geowebchat

@dianashk Jul 07, 1:10pm @philiphubs @mappingmashups thanks for hosting and moderating #geowebchat

@philiphubs Jul 07, 1:12pm #geobreakfast latitude: 37.7651215, longitude: -122.4226074 next Friday 8:30-10 am #geowebchat – Thanks @erictheise

@vicchi Jul 07, 1:21pm @dianashk @philiphubs @mappingmashups Perfectly said, #geowebchat is an geo-institution
