Next #geowebchat, October 1: Techniques and conventions for geoweb cartography

By Alan | Published: September 28, 2013

In honor of the upcoming annual conference of the North American Cartographic Information Society (NACIS), our next #geowebchat will focus on the unique challenges of making maps for the geoweb. In what ways can geoweb maps follow the same cartographic conventions as printed maps, and in what ways must they differ?

In some cases, such as the popular Wind Map, the geoweb affords new ways of presenting information that seem to be unlike anything possible in traditional cartography. Are there conventions for these emerging map types? What can be learned from older maps, or from present-day non-cartographic visualizations?

On the other hand, geoweb cartographers are confronted with many of the same challenges as traditional cartographers, such as how to place a large number of city labels on a map. However, on the geoweb these tasks cannot be done by hand, because web maps frequently must function at multiple scales and with massive, dynamic data sources. Can label placement algorithms create maps as well as human cartographers, and do the same cartographic “rules” apply?

Join the discussion and let us know whether you think geoweb cartography is truly a new paradigm, or whether cartographically speaking, “there’s nothing new under the sun”.

As always, the #geowebchat takes place on Tuesday at noon PDT (3pm EDT, 8pm BST). Log on to twitter and follow the hashtag #geowebchat to listen in or join the conversation.

For further reading, you can check out some of our earlier conversations about geoweb cartography, from 2011 and 2012:

#geowebchat transcript, 17 September 2013: Diversity in geoweb communities

By Alan | Published: September 17, 2013


@mappingmashups Sep 17, 10:03am Today, noon PT, 3pm ET, 8pm BST: we’re talking about diversity on the #geoweb. Join the conversation on #geowebchat! mappingmashups.net/2013/09/16/nex…

@jgieseking Sep 17, 11:48am How do different kinds of diversity manifest (or fail to manifest) on the #geoweb? Tune into #geowebchat at 3pm US EST for the chat. I’m in!

@mappingmashups Sep 17, 12:01pm Hello everyone! Welcome to today’s #geowebchat! We’re talking about diversity on the geoweb.

@mappingmashups Sep 17, 12:02pm If you want to join the chat, use the hashtag #geowebchat in all your tweets! Or to ignore us, mute that hashtag in your twitter client.

@JacqInTheBooks Sep 17, 12:02pm Hey #geowebchat! Looking forward to talking diversity today … great topic!

@mappingmashups Sep 17, 12:02pm I also suggest tweetchat.com/room/geowebchat as a handy way to follow along with #geowebchat

@JacqInTheBooks Sep 17, 12:05pm Btw I also continue to collect #geowebchat posts for my PhD research. Check out informallearningonline.webs.com Msg me if you have concerns/comments

@mappingmashups Sep 17, 12:05pm There’s been interesting developments in the discussion of diversity in OpenStreetMap lately… #geowebchat

@mappingmashups Sep 17, 12:06pm …such as @alyssapwright’s keynote at #sotm13 on diversity in #osm: slideshare.net/apw217/changin… #geowebchat

@mappingmashups Sep 17, 12:07pm And #osm has a new diversity mailing list that I recommend everybody check out: lists.openstreetmap.org/listinfo/diver… #geowebchat

@JessiBreen Sep 17, 12:07pm There’s also @geographiliac ‘s recent paper. #geowebchat

@Brobdingnag Sep 17, 12:08pm @mappingmashups @alyssapwright Someone last week pointed out it is very similar to wikipedia diversity problems #geowebchat

@jgieseking Sep 17, 12:10pm @JacqInTheBooks I can’t imagine ethics concerns w tweet collections since all are catalogued by services & @librarycongress. :) #geowebchat

@ebrelsford Sep 17, 12:11pm Are there geoweb communities outside of #osm that are talking about diversity right now? #geowebchat

@jgieseking Sep 17, 12:11pm @Brobdingnag @mappingmashups @alyssapwright It’d be grt to jump into @FemTechNet / @crunkfeminists’ Wikipedia takeovers w #geowebchat frame.

@mappingmashups Sep 17, 12:13pm (Sorry all on #geowebchat, I’m a bit distracted in physical space right now… hope you all can get the conversation started yourselves!)

@JessiBreen Sep 17, 12:14pm I think diversity, maybe not by that title, is a fairly common interest in tech community right now. #geowebchat

@mappingmashups Sep 17, 12:16pm Here’s @geographiliac’s paper @JessiBreen mentioned: link.springer.com/article/10.100… (paywall) #geowebchat (earlier version: floatingsheep.org/2012/07/sheepc…)

@spara Sep 17, 12:16pm So is this a gender thing, a philosophical thing, a political economy thing, a xxxxx thing, all of the aboev? #geowebchat

@JessiBreen Sep 17, 12:17pm Also the great video of @geographiliac’s presentation from Sheep Camp on the topic: vimeo.com/44870758 #geowebchat

@JessiBreen Sep 17, 12:17pm @spara Gender is certainly an obvious one, but I think they all need addressing. #geowebchat

@spara Sep 17, 12:18pm @JessiBreen Agreed, anyone got a framework on how to approach the elephant? #geowebchat

@JacqInTheBooks Sep 17, 12:21pm @JessiBreen Agree. More ques are asked re: diversity/equal representation (or lack of) in online communities. See it in edu too! #geowebchat

@JessiBreen Sep 17, 12:22pm @JacqInTheBooks Yes, this is not exclusively a geoweb thing, it’s evident in lot of expert communities. #geowebchat

@rastrau Sep 17, 12:22pm @JacqInTheBooks @JessiBreen Also very relevant re: democratisation potential (hype?) of #OGD and #opendata in general, imo. #geowebchat

@jgieseking Sep 17, 12:23pm @spara All of the above. The heteronormativity of “family”-based units in most census data is one appalling element of ++ #geowebchat

@jgieseking Sep 17, 12:23pm @spara ++ inequality that is a both philosophical & key to political economy. #geowebchat

@JacqInTheBooks Sep 17, 12:23pm @spara @JessiBreen Do you think the diversity probs r understood sufficiently yet to develop frameworks on how to approach them? #geowebchat

@JessiBreen Sep 17, 12:24pm @JacqInTheBooks @spara The recent OSM US meeting had some pretty damning data. I think there’s enough to start. #geowebchat

@JacqInTheBooks Sep 17, 12:24pm @spara @JessiBreen i.e. why gaps exist? #geowebchat

@spara Sep 17, 12:26pm So could we agree that carving out spatial out of the larger diversity conversation is the thing to focus on? #geowebchat

@Brobdingnag Sep 17, 12:27pm @JacqInTheBooks @spara @JessiBreen This paper suggests some reasons why the gaps exist journals.uic.edu/ojs/index.php/… #geowebchat

@jgieseking Sep 17, 12:27pm @mappingmashups Thx for sharing @geographiliac’s #Gender + #GeoWeb paper–& #OA lack on much of our work highlights #geowebchat inequalities

@JacqInTheBooks Sep 17, 12:27pm @Brobdingnag @spara @JessiBreen Thanks will check it out! #geowebchat

@mappingmashups Sep 17, 12:28pm @spara Well, spatial’s the thing for us to focus on because this is #geowebchat! & helps us find new angles to address diversity issue.

@JessiBreen Sep 17, 12:29pm @mappingmashups Well, in the case of mapping, you’re working against a long history of a white guys only club. #geowebchat

@mappingmashups Sep 17, 12:30pm But I also think the diversity problems of tech in general (like the Reagle paper @Brobdingnag shared) deeply warp the geoweb. #geowebchat

@spara Sep 17, 12:31pm I would hold Wild Bill Bunge as an exemplar of diversity in geography #geowebchat

@mappingmashups Sep 17, 12:31pm It’s been a bad few weeks for sexism in tech in general, with the #titstare incident, etc… actually, it’s always a bad week. #geowebchat

@Brobdingnag Sep 17, 12:33pm In the wikipedia gender gap people talk about how women have less freetime than men (are most OSM edits made in freetime?) #geowebchat

@AllFourPaws_SEA Sep 17, 12:34pm @JessiBreen Check out Marie Tharp for a counter example for marine mapping. #geowebchat

@JessiBreen Sep 17, 12:34pm @AllFourPaws_SEA @JessiBreen Will do! #geowebchat

@AllFourPaws_SEA Sep 17, 12:37pm At yesterday’s #cyberGIS meeting Michael Goodchild commented on generation gap “can oldsters even recognize new developments?” #geowebchat

@AllFourPaws_SEA Sep 17, 12:38pm #geowebchat I would disagree with MG but it points to an interesting other possible lack of diversity

@mappingmashups Sep 17, 12:42pm (Hi everybody, I’m catching up on the #geowebchat tweets so far…)

@JessiBreen Sep 17, 12:43pm @mappingmashups Are we on the big screen this week? #geowebchat

@rdhyee Sep 17, 12:43pm @mappingmashups Is #geowebchat happening (more) synchronously right now?

@mappingmashups Sep 17, 12:44pm A link to Marie Tharp that @AllFourPaws_SEA mentioned: huffingtonpost.com/hali-felt/mari… #geowebchat

@mappingmashups Sep 17, 12:45pm @JessiBreen Yes, I just popped you all up on the big screen at @stamen for the final 15 minutes. Make it good, #geowebchat!

@spara Sep 17, 12:45pm Marie Tharp’s bathymetry map is available via WMS #geowebchat

@mappingmashups Sep 17, 12:46pm @rdhyee Not sure if it’s happening more synchronously, or just erratically… was tweeting from a meeting during the first half #geowebchat

@neogeografen Sep 17, 12:47pm @Brobdingnag I think @pascal_n have some figures what time of the day/week most OSM editing take place #geowebchat

@AllFourPaws_SEA Sep 17, 12:48pm Great interview with Marie Tharp at aip.org/history/ohilis… #geowebchat Thanks for huffpost and WMS links

@JessiBreen Sep 17, 12:48pm @Brobdingnag That’s an interesting thought. #geowebchat

@mappingmashups Sep 17, 12:49pm @AllFourPaws_SEA RE: the idea of “oldsters” getting involved: the elderly are overrepresented in volunteer contexts offline… #geowebchat

@jgieseking Sep 17, 12:49pm Who examines intersectionalities in #geography? @demonicground, G Pratt, & M Wright’s work are the best in my opinion. #geowebchat

@MapGoddess Sep 17, 12:52pm @mappingmashups including volunteering in technology related areas?? #geowebchat @AllFourPaws_SEA

@mappingmashups Sep 17, 12:53pm @MapGoddess No, I think not, primarily non-technical areas. But I wonder if that is changing? I don’t have any stats. #geowebchat

@JessiBreen Sep 17, 12:53pm @mappingmashups @AllFourPaws_SEA I wonder what happens if you could account for differences in the quantity of freetime. #geowebchat

@AllFourPaws_SEA Sep 17, 12:54pm @MapGoddess @mappingmahsups #geowebchat A coming tidal wave of digital-savvy grannies could be a very powerful force.

@mappingmashups Sep 17, 12:55pm @JessiBreen It seems unlikely that amount of free time can explain 20:1 male to female contributor ratios… #geowebchat

@Brobdingnag Sep 17, 12:55pm We haven’t talked much about geographic diversity, are most OSM users from the US and GB? #geowebchat

@spara Sep 17, 12:56pm @Brobdingnag I thought they were Germans #geowebchat

@mappingmashups Sep 17, 12:56pm @Brobdingnag Not US and GB specifically (DE is near the top!), but certainly wealthier countries have greater representation. #geowebchat

@JacqInTheBooks Sep 17, 12:56pm @Brobdingnag Also the issue of urban versus rural users #geowebchat

@JessiBreen Sep 17, 12:57pm @mappingmashups Not gender, but the age thing maybe. #geowebchat

@mhaklay Sep 17, 12:57pm Maybe it came up, but in case that you missed is – see the project by @lesewesen et al cartography.tuwien.ac.at/fem2map/ #geowebchat

@neogeografen Sep 17, 12:57pm @AllFourPaws_SEA FYI- #1 female mapper in OSM Denmark is a grandma (retired teacher) #geowebchat @MapGoddess

@spara Sep 17, 12:57pm @JacqInTheBooks @Brobdingnag I wonder if connectedness via the Internet correlates to density of OSM mapping #geowebchat

@mappingmashups Sep 17, 12:58pm Regarding other types of diversity: Here is well-developed OSM proj to map wheelchair accessibility: wiki.openstreetmap.org/wiki/Wheelmap #geowebchat

@AllFourPaws_SEA Sep 17, 12:58pm #geowebchat Countries where govt. digital data is free (US) vs where digital data is expensive (Europe)?

@mappingmashups Sep 17, 12:59pm One thing we didn’t touch on is whether diverse mappers make different maps. Marie Tharp reminds us: not necessarily #geowebchat

@JessiBreen Sep 17, 1:00pm @Brobdingnag @mappingmashups Depends on where is being mapped, doesn’t it? #geowebchat

@neogeografen Sep 17, 1:00pm @Brobdingnag Figures about how large OSM in diff. count. are a hint here osmstats.altogetherlost.com/index.php?item… #geowebchat – DE 2X nummer two daily contr.

@Brobdingnag Sep 17, 1:00pm Wonder what it would take for OSM to catch on the Global South. More People of Color, also just more people #geowebchat

@mappingmashups Sep 17, 1:00pm Unfortunately we’re already out of time in this #geowebchat! Sorry it was more scattered than usual. Will definitely return to this topic.

@mappingmashups Sep 17, 1:01pm But by all means, continue the conversation, everybody! #geowebchat

@spara Sep 17, 1:01pm More reading material to explore diversity, so good #geowebchat

@JacqInTheBooks Sep 17, 1:01pm @spara @Brobdingnag I would suspect this has an impact, but also likely related with other issues as well, SES, age perhaps? #geowebchat

@JessiBreen Sep 17, 1:02pm @Brobdingnag I’m interested to see what the change in editing tools in OSM (iD) does for participation. #geowebchat

@re_sieber Sep 17, 1:03pm Greetings from the Netherlands. Sorry I missed #geowebchat

@mappingmashups Sep 17, 1:03pm Next #geowebchat will be in 2 weeks, on Oct 1, same time. I think we’ll have a cartography topic in honor of #NACIS dev.nacis.org/index.cfm?x=2

@spara Sep 17, 1:03pm @JacqInTheBooks @Brobdingnag Lots of variables to consider – age, occupation, ethnicity, education, on and on #geowebchat

@spara Sep 17, 1:03pm @mappingmashups Label placement algorithms! #geowebchat

@JacqInTheBooks Sep 17, 1:05pm @spara @Brobdingnag Yes, don’t think they can be considered in isolation from one another – very much interrelated #geowebchat

@enf Sep 17, 1:13pm @Brobdingnag Peak time for changeset submission seems to be 9pm in the time zone of the area being mapped #geowebchat pic.twitter.com/mvW5jnD55X

@pascal_n Sep 17, 1:32pm .@neogeografen @Brobdingnag you can also find some interesting stuff here: mdpi.com/2220-9964/1/2/… #OpenStreetMap #Activity #2012 #geowebchat

@peterajohnson Sep 17, 5:30pm “@JessiBreen: interested to see what iD does for #OSM participation. #geowebchat” It has to be a huge positive. Shows maturation of platform

Next #geowebchat: diversity in geoweb communities

By Alan | Published: September 16, 2013

In our next #geowebchat (on Tuesday September 17) we will discuss diversity on the geoweb, and in particular the online communities that create geospatial data and tools on the web. What are the problems that result from lack of diversity, how did the situation get this way, and what can be done to improve it?

In this discussion we will discuss all kinds of diversity, such as gender, race, sexual orientation, ability, education level, and so forth. How do different kinds of diversity manifest (or fail to manifest) on the geoweb? Does diversity along one axis in a community (such as gender parity) help support other kinds of diversity, or does each kind of diversity need to be addressed separately?

As background material, I would recommend watching Alyssa Wright’s keynote at OpenStreetMap’s State of the Map conference from earlier this month, titled “Changing the Ratio of OpenStreetMap”.
Video: http://citizen.civico.net/openstreetmapfoundation/stateofthemap/1143
Slideshare: http://www.slideshare.net/apw217/changing-the-ratio

You can also read one of our geowebchats from last year, specifically on the topic of gender and geosocial networking: http://mappingmashups.net/2012/04/03/geowebchat-transcript-3-april-2012/

As always, the #geowebchat takes place on twitter for one hour starting at 12 noon PDT, 3pm EDT, 8pm BST. Just log onto twitter and follow the hashtag #geowebchat to join in the discussion.

For more information about #geowebchat, and to read transcripts of previous chats, go here: http://mappingmashups.net/geowebchat/

Looking forward to chatting with you!

#geowebchat transcript, 20 August 2013

By Alan | Published: August 21, 2013


@mappingmashups Aug 20, 10:41am Reminder: #geowebchat today about teaching webmapping tools and techniques in non-academic contexts. Join us at 12pm PT, 3pm ET, 8pm BST!

@skorasaurus Aug 20, 11:07am come talk about what #geoweb meetups around USA like @opengeocle are doing @ 3pm EST @ today’s #geowebchat

@AndrewShears Aug 20, 11:34am Not going to make it to #geowebchat today. Looking forward to the transcript though.

@skorasaurus Aug 20, 11:56am what sites do peeps use to follow the #geowebchat again ? (I need to finally bookmark them!)

@mappingmashups Aug 20, 11:56am Starting in a few minutes: #geowebchat about “geoweb pedagogy outside the academy”. Join in! Try tweetchat.com/room/geowebchat to follow along.

@mappingmashups Aug 20, 11:56am Another one to try is twitterfall.com for #geowebchat.

@lyzidiamond Aug 20, 12:01pm Excited for #geowebchat!

@mappingmashups Aug 20, 12:03pm Welcome everybody to #geowebchat!

@mappingmashups Aug 20, 12:04pm As usual, if you want to ignore us, see if your twitter client lets you mute the #geowebchat hashtag. But we hope you won’t!

@re_sieber Aug 20, 12:04pm #geowebchat-on pedagogy &#neogeoweb – I thought all instruction outside the academy was DIY like #codeacademy

@JacqInTheBooks Aug 20, 12:05pm Hi all! Excited for today’s #geowebchat! Pedagogy outside the academy is right up my alley. Been reading on geospatial citizenship/literacy

@Geoteq Aug 20, 12:05pm Yo, greetings from Brazil. In listening. =) #geowebchat

@re_sieber Aug 20, 12:05pm Or is the today’s #geowebchat ab how academics can use outside sources for #geoweb instruction?

@mappingmashups Aug 20, 12:06pm @re_sieber We might include things like #codeacademy and MOOCs as geoweb pedagogy outside the academy, but it’s not only that #geowebchat

@JacqInTheBooks Aug 20, 12:06pm I’m still collecting #geowebchat tweets for my PhD research- informallearningonline.webs.com Msg me w/ any questions or if u want your posts excluded

@mappingmashups Aug 20, 12:06pm …and we’ve already had one chat recently about MOOCs, so I’d like to talk about other alternative spaces and contexts #geowebchat

@andrewbt Aug 20, 12:06pm Listening to #geowebchat after @mapadelphia told me about it!

@mappingmashups Aug 20, 12:07pm @re_sieber I think academics inevitably have to use sources outside of academic ones, because there are few sources otherwise #geowebchat

@re_sieber Aug 20, 12:07pm @JacqInTheBooks Today’s #geowebchat could be ab the literacies required for #neogeoweb

@mappingmashups Aug 20, 12:08pm But I have a personal interest now in thinking about teaching/learning forums totally outside academia… specifically #maptime! #geowebchat

@re_sieber Aug 20, 12:09pm I think #citsci initiatives like Crowdsourcing, for the Birds nytimes.com/2013/08/20/sci… count as geoweb pedagogy outside academy #geowebchat

@mappingmashups Aug 20, 12:09pm Quick def’n of #maptime: a recurring learning and hack night we started hosting at @stamen. Inspired by classes at hackerspaces #geowebchat

@mappingmashups Aug 20, 12:10pm So we have started @MaptimeSF, and @skorasaurus has started one in Cleveland, and there are a few other nascent #maptimes. #geowebchat

@lyzidiamond Aug 20, 12:11pm @mappingmashups What is the structure of @MaptimeSF at this point? #geowebchat

@mappingmashups Aug 20, 12:11pm At #maptime people can bring their own projects & ask Qs, or work on predefined lessons or projects if they don’t have their own #geowebchat

@re_sieber Aug 20, 12:11pm Literacies for #neogeoweb: geography/loc, domain (eg birds), user interface #geowebchat. Coding?

@mapadelphia Aug 20, 12:11pm We’re looking to get an open & inclusive geo / spatial meetup going in Philadelphia- Any tips, tricks, advice, cautionary tales? #geowebchat

@alyssapwright Aug 20, 12:11pm we’re at the very beginnings of brining #maptime to NYC in coordination #geonyc and #betanyc cc @noneck #geowebchat

@skorasaurus Aug 20, 12:12pm reason started 1 in #cle – there’s little/no #geoweb (or civic hacking) culture outside the workplace #geowebchat

@mappingmashups Aug 20, 12:12pm @lyzidiamond So far we’ve only had 4 or 5 maptimes, and they vary a lot. But the idea is to be low-key and somewhat unstructured #geowebchat

@alyssapwright Aug 20, 12:13pm i think it’s the weekly meeting up that will make it sustainable. and at the same time who can commit once a week? #geowebchat

@mappingmashups Aug 20, 12:13pm We are trying to make it very inviting for newbies. Luckily enough experts show up to answer questions and guide the learning. #geowebchat

@JacqInTheBooks Aug 20, 12:13pm @re_sieber I agree & a very interesting project. I know someone involved & she learnt a lot about both birds & the #geoweb #geowebchat 1/2

@mappingmashups Aug 20, 12:14pm @re_sieber Even #coding can be a part of it, if that’s what ppl wanna learn. We introduced a few people to github last time. #geowebchat

@lyzidiamond Aug 20, 12:14pm Geo students at UWisconsin started a group with presentations + a blog to share, which is now giscollective.org. (1/2) #geowebchat

@lyzidiamond Aug 20, 12:14pm I think a wiki or blog to go along with the meetups can be good for those who can’t attend each week to learn what they missed. #geowebchat

@JacqInTheBooks Aug 20, 12:14pm @re_sieber Certainly has increased her #geoweb literacy through the project as you mentioned! #geowebchat

@re_sieber Aug 20, 12:14pm @skorasaurus Disagree. There’s plenty of civic hacking ab #opendata. Also #OSM #geowebchat All hinges, though, on how you define #geoweb

@bethschechter Aug 20, 12:15pm @mappingmashups @lyzidiamond so, we’re learning that unstructured is good for some, but that others need structure
#geowebchat

@lyzidiamond Aug 20, 12:15pm Oh yeah, followers of mine who don’t care about #geowebchat + think I’m being super annoying can mute the tag!

@bethschechter Aug 20, 12:15pm @mappingmashups @lyzidiamond so with this in mind, we’re trying to think of ways to incorporate both. #geowebchat

@mappingmashups Aug 20, 12:15pm @lyzidiamond We have a chaotic blog here: maptimesf.tumblr.com and a sparse github repo/wiki here: github.com/maptime/maptime #geowebchat

@lyzidiamond Aug 20, 12:16pm @mappingmashups I also love that @MaptimeSF works on group projects, so progress is tracked on github! #geowebchat

@bethschechter Aug 20, 12:16pm @mappingmashups @lyzidiamond one idea is to have ongoing structured activities in one room, and free project times in another #geowebchat

@mapadelphia Aug 20, 12:16pm @glenfarrelly Exactly. We want to include hobbyists & experts alike. Maybe partnering with a few other meetups to get going? #geowebchat

@skorasaurus Aug 20, 12:16pm @re_sieber – nationally, I agree, although not so much in #cleveland yet. #geowebchat

@mappingmashups Aug 20, 12:17pm @skorasaurus @re_sieber It’s true that #maptimeSF should be considered in the #SF context: we have a surfeit of geo events… #geowebchat

@alyssapwright Aug 20, 12:17pm @mapadelphia @glenfarrelly we’ve been trying to partner with the @codeforamerica brigade in NYC through #BetaNYC #geowebchat

@mappingmashups Aug 20, 12:18pm @skorasaurus @re_sieber …but very few that are accessible to newbies. #geowebchat

@re_sieber Aug 20, 12:18pm @bethschechter @mappingmashups @lyzidiamond Negotiating level of structure&coding skills @ meetups crucial 4 sustained interest #geowebchat

@andrewbt Aug 20, 12:18pm What makes @MaptimeSF different than a #cfabrigade meetup? The explicit geo focus, or something else? #geowebchat

@skorasaurus Aug 20, 12:18pm .@mapadelphia we hold our bi-weekly mtgs w/ @codeforamerica ‘s #summit cnty/akron bridgade. #geowebchat

@mappingmashups Aug 20, 12:19pm So, we’d love people to start #maptime in other cities, but if your city has no #geo events at all maybe you need a diff format? #geowebchat

@bethschechter Aug 20, 12:19pm @lyzidiamond more documentation is totally needed! it just ends up being a looooong day. I’ve fallen asleep writing blog posts #geowebchat

@lyzidiamond Aug 20, 12:19pm On navigating variable skill level in meetups: PDX Python has a beginner table w/ mentors to help get folks started/answer q’s. #geowebchat

@lyzidiamond Aug 20, 12:19pm @mappingmashups Why would a different format be necessary? #geowebchat

@skorasaurus Aug 20, 12:20pm @mappingmashups we’ve had bi-monthly mtgs consisting of instructional presentations #geowebchat

@spara Aug 20, 12:20pm @mappingmashups What about #geobreakfast? #geowebchat

@mappingmashups Aug 20, 12:20pm @lyzidiamond I’m asking all of you! But like in @mapadelphia’s case, maybe you’re thinking of something more like #geoDC… #geowebchat

@lyzidiamond Aug 20, 12:21pm @mappingmashups What is #geodc all about? #geowebchat

@mappingmashups Aug 20, 12:21pm @lyzidiamond …something with organized presentations every month, instead of workshop-style? They serve diff needs. #geowebchat

@re_sieber Aug 20, 12:21pm @lyzidiamond @mappingmashups on diff format for #geo-Depends on how much geog (ie geometry&topology) is important 4data handling #geowebchat

@lyzidiamond Aug 20, 12:22pm Another thing PDX Python does: 2nd Tuesday presentation night, 4th Tuesday hack night. #geowebchat

@mappingmashups Aug 20, 12:22pm Even though #maptime is more workshop-style, we hope to keep including brief presentations too. We’ve done “5 min definitions” #geowebchat

@JessiBreen Aug 20, 12:22pm @mappingmashups @lyzidiamond And beer. #geodc is short talks, maps and beer. #geowebchat

@mappingmashups Aug 20, 12:23pm @spara Yes, every city should also have a #geobreakfast and a #geobeers/#geoHH. #geowebchat

@re_sieber Aug 20, 12:23pm @lyzidiamond @mappingmashups How #geo is different: depends on how good cartography is of platform. Can’t take that as given #geowebchat

@alyssapwright Aug 20, 12:23pm @andrewbt @MaptimeSF in NYC we’re trying to combine the two, but bringing explicit spatial training and expertise into the mix. #geowebchat

@lyzidiamond Aug 20, 12:23pm I kinda like the idea of a hack night with a built-in mechanism for lightning talks. Every 30 minutes bell rings, someone talks. #geowebchat

@mappingmashups Aug 20, 12:24pm @re_sieber Maybe because I used “hack” you are thinking that civic hacking is the focus? I think for us the mapiness is focus. #geowebchat

@bethschechter Aug 20, 12:24pm @andrewbt @MaptimeSF #maptimesf is geared toward coding beginners, and there’s a digital #geo + dataviz focus. #geowebchat

@re_sieber Aug 20, 12:25pm @lyzidiamond @mappingmashups How #geo is different: depends on how well ppl understand aggregation, gerrymandering #geowebchat

@mappingmashups Aug 20, 12:25pm @re_sieber … so it’s like a hackerspace Arduino circuit-hacking night, just with maps instead. Less like a hackathon #geowebchat

@lyzidiamond Aug 20, 12:26pm The challenge is pulling in devs who want to learn geo AND geo folks who want to learn coding. Can it be symbiotic? #geowebchat

@mappingmashups Aug 20, 12:26pm @re_sieber But of course within the maphacking framework, we have plenty of activist motivation. Such as the Water Atlas project #geowebchat

@bethschechter Aug 20, 12:26pm @lyzidiamond so, yes, that can work. It’s important to make sure people who are there to learn and work have the space to do so #geowebchat

@re_sieber Aug 20, 12:28pm @mappingmashups there are literacies needed for Arduino & literacies needed for #geo Are we talking ab who convenes hackspc? #geowebchat

@mappingmashups Aug 20, 12:28pm @lyzidiamond We also have lots of people who are neither devs nor geo people. #geowebchat

@re_sieber Aug 20, 12:29pm @lyzidiamond ‘devs who want to learn geo AND geo folks who want to learn coding. Can it be symbiotic?’ #geowebchat Maybe parasitic? ;-)

@mappingmashups Aug 20, 12:31pm @re_sieber The “conveners” set agenda & frame, but also provides expertise for assistance. …but experts aren’t strictly reqd. #geowebchat

@geothinkca Aug 20, 12:32pm Hi #geowebchat! So just joined and not sure where the conversation is — are we talking ab outside resources 4 academics to learn #geoweb?

@alyssapwright Aug 20, 12:32pm @re_sieber i think it can be symbiotic. but it’s also goes beyond learning to building things with complementary skills. #geowebchat

@vtcraghead Aug 20, 12:32pm @mappingmashups @lyzidiamond Such people exist? I though we all fell somewhere on the continuum :) #geowebchat

@mappingmashups Aug 20, 12:32pm @re_sieber I could imagine a bunch of map lovers gathering to self-teach from books (& our #maptime materials) w/out experts. #geowebchat

@mappingmashups Aug 20, 12:33pm @geothinkca We’re talking about spaces to teach and learn the geoweb outside academia. #geowebchat

@spara Aug 20, 12:33pm @mappingmashups @re_sieber I think this is the right approach #geowebchat

@re_sieber Aug 20, 12:33pm @mappingmashups Interesting ab activist motivation in maphacking-what drives them? Water? Coding? Counter-mapping? Maps? Beer? #geowebchat

@mappingmashups Aug 20, 12:34pm @geothinkca Which brings up a question we haven’t addressed head-on. WHY have non-academic venues at all? Opinions? #geowebchat

@Geoteq Aug 20, 12:34pm @re_sieber It depends of kind of “Geo”. There is the hard geo and there is the Geo u can use data and tools to create something. #geowebchat

@re_sieber Aug 20, 12:35pm @alyssapwright “goes beyond learning to building things with complementary skills” YES. Latter is something we academics forget #geowebchat

@mappingmashups Aug 20, 12:35pm @re_sieber Maps are fun and all, but to give up your evening to learn maps, it helps to have another (activist?) motive. #geowebchat

@skorasaurus Aug 20, 12:35pm @mappingmashups there’s innovation, collaboration, culture that exists outside the strict workplace and academia. #geowebchat

@vtcraghead Aug 20, 12:35pm @mappingmashups @geothinkca We could probably coax an opinion about that out of @PostPostGIS #geowebchat #theacademicsystemiscoopted

@JessiBreen Aug 20, 12:35pm @mappingmashups Wait, WHY non-academic venues is really a question? #geowebchat

@re_sieber Aug 20, 12:36pm @alyssapwright And I’ll be at Columbia during the Fall (sabbatical!) so maybe we can chat more about this #geowebchat

@Geoteq Aug 20, 12:36pm @re_sieber hard Geo: Geodesy, Remote Sensing, Cartography Math, GNSS treatment signal, etc.
#geowebchat

@lyzidiamond Aug 20, 12:37pm The academy is so limiting: time, money, bureaucracy, etc. #geowebchat

@geothinkca Aug 20, 12:38pm @lyzidiamond but isn’t profit margins and agenda keeping also limiting? #geowebchat

@lyzidiamond Aug 20, 12:39pm I loved my university geography/GIS program. But I didn’t learn anything tech-wise outside of certain proprietary software. #geowebchat

@re_sieber Aug 20, 12:39pm @Geoteq Those subjects may hurt the brains of map lovers, who just want to have fun w maps (“but you can’t wo geodesy!’) ;-) #geowebchat

@lyzidiamond Aug 20, 12:39pm @geothinkca … not sure I see your point? #geowebchat

@spara Aug 20, 12:40pm I don’t think a hard/soft geo distinction is helpful. Skill are skills, you acquire them as needed #geowebchat

@alyssapwright Aug 20, 12:40pm @spara agreed. i sort of think we’re missing the point here… #geowebchat

@spara Aug 20, 12:41pm Academic geo is meta, civilian geo is purpose driven #geowebchat

@re_sieber Aug 20, 12:42pm @lyzidiamond This speaks to larger issue of engaging people to use their brains outside a structured course #geowebchat 1/2

@mappingmashups Aug 20, 12:42pm @lyzidiamond @geothinkca You’re saying that industry has as many limitations as academia, and that’s certainly true… #geowebchat

@spara Aug 20, 12:42pm People want map things for a reason, that’s why they give up evenings and weekends
#geowebchat

@re_sieber Aug 20, 12:42pm @lyzidiamond @lyzidiamond This also speaks to larger issue of making coding/hacking less intimidating #geowebchat 2/2

@mappingmashups Aug 20, 12:42pm @lyzidiamond @geothinkca …And we haven’t talked much about workshops you have to pay for, and certification programs, etc… #geowebchat

@sashacuerda Aug 20, 12:42pm @geothinkca @lyzidiamond as if unis are not profit / agenda driven!!! #geowebchat

@alyssapwright Aug 20, 12:42pm my thinking: people want to make maps (responsibily) because they have something else they want to say/do/see/understand #geowebchat (1/2)

@bethschechter Aug 20, 12:43pm @JessiBreen @mappingmashups that’s a great question! For me, i still want to learn but am done with school. gal’s gotta work. #geowebchat

@mappingmashups Aug 20, 12:44pm @lyzidiamond @geothinkca …we should talk about those, too, but #maptime is cheap to run, w/ vol. labor & space (thnx @stamen!) #geowebchat

@re_sieber Aug 20, 12:44pm I wonder if hackerspaces as we conceive of them are gendered, intimidating to women, & how to change that #geowebchat

@bethschechter Aug 20, 12:45pm @JessiBreen @mappingmashups also, yes, school is expensive. Also…is the academy the best place to learn skills? debatable… #geowebchat

@spara Aug 20, 12:45pm re: hacker spaces textfiles.com/uploads/hackin… #geowebchat

@lyzidiamond Aug 20, 12:45pm @JacqInTheBooks I think that having beginner tables as well as space for non-beginners can help make things less intimidating #geowebchat

@geothinkca Aug 20, 12:46pm @mappingmashups @lyzidiamond exactly. diffs are many but the coop btwn the two important. Masters aside its a matter of impact #geowebchat

@bethschechter Aug 20, 12:46pm @re_sieber hackerspaces are intimidating to a lot of people! As are API libraries and other online resources. #geowebchat

@re_sieber Aug 20, 12:46pm @bethschechter @JessiBreen @mappingmashups We are told @ my university that we CANNOT teach skills #geowebchat

@spara Aug 20, 12:47pm @re_sieber @bethschechter @JessiBreen @mappingmashups Whaaaaa? #geowebchat

@alyssapwright Aug 20, 12:47pm many opportunities to learn geo in service to a larger goal. hard part is building the structured open space for learning. #geowebchat

@mappingmashups Aug 20, 12:47pm We do want to make #maptime inviting to a very diverse audience. But I think we could also have done it at a hackerspace… #geowebchat

@JessiBreen Aug 20, 12:47pm @bethschechter @mappingmashups Maps are power. Of course geoweb needs to get out of the academy & into the hands of the public. #geowebchat

@bethschechter Aug 20, 12:47pm @re_sieber getting people together who are all learning, and putting them on a project together, allows them to learn together #geowebchat

@spara Aug 20, 12:47pm @alyssapwright Why structured? #geowebchat

@mappingmashups Aug 20, 12:47pm …individual outreach to get diverse audiences to these events is key, no matter where they’re held. #geowebchat

@bethschechter Aug 20, 12:48pm @re_sieber add experts to the mix, to help answer questions, and you’ve got a good thing going :) #geowebchat

@bethschechter Aug 20, 12:48pm @mappingmashups what do you mean by doing it as a hackerspace? how would #maptime be different? #geowebchat

@alyssapwright Aug 20, 12:48pm @spara it can’t happen every once in a while — you can count on it and on progress. something that says: “I’m getting better.” #geowebchat

@JacqInTheBooks Aug 20, 12:49pm @lyzidiamond Agreed! Online spaces seem safer for beginners too – can ‘lurk & learn’! #geowebchat

@lyzidiamond Aug 20, 12:49pm @mappingmashups This is why refreshments are so great! :) #geowebchat

@spara Aug 20, 12:49pm The hackerdojo.com model of engagement teaches kids to program all over the world. Why not have one for geo? #geowebchat

@re_sieber Aug 20, 12:49pm @spara @bethschechter @JessiBreen @mappingmashups Skills obsolesce; we’re supposed to teach critical thinking in our university #geowebchat

@Geoteq Aug 20, 12:49pm @bethschechter Concepts r important. It’s through them that can handle any softw. If u know de concept software do not interest #geowebchat

@spara Aug 20, 12:49pm Damn you twitter, the last tweet references hackerdojo #geowebchat

@mappingmashups Aug 20, 12:50pm @bethschechter I mean, I would’ve been equally comfortable hosting at @noisebridge, for ex. You still have to actively invite. #geowebchat

@alyssapwright Aug 20, 12:50pm #maptime is not hacking or workshops — it’s a way to transform the hackathons into sustainable learning and building spaces. #geowebchat

@spara Aug 20, 12:50pm @re_sieber @bethschechter @JessiBreen @mappingmashups critical thinking and $2.50 will get you a cup of coffee at starbucks #geowebchat

@re_sieber Aug 20, 12:50pm @bethschechter in Maker community, there’s lots of diff in activities by gender #geowebchat

@alyssapwright Aug 20, 12:51pm @JacqInTheBooks i find online spaces are often hostile to beginners. harder to fine mentorship and apprenticeship. #geowebchat

@re_sieber Aug 20, 12:52pm @spara @bethschechter @JessiBreen @mappingmashups I’ve done so much critical thinking, I’m ready to open a coffee shop #geowebchat

@mappingmashups Aug 20, 12:52pm (FYI, this chat is being projected on the big screen during @stamen’s lunch hour. You’re all famous!) #geowebchat

@spara Aug 20, 12:53pm crap, I meant coderdojo coderdojo.com not hackerdojo, as model of pedagogy outside academia #geowebchat

@geographerliz Aug 20, 12:53pm Agree to a point, though the lines are starting to blur as uni’s struggle MT @spara: Acad geo is meta, civ geo is purpose driven #geowebchat

@JessiBreen Aug 20, 12:53pm @mappingmashups @stamen *waves* #geowebchat

@bethschechter Aug 20, 12:54pm @mappingmashups oh, I see what you’re saying. Yes. @stamen works so well, since we work here. But @noisebridge is super close! #geowebchat

@re_sieber Aug 20, 12:54pm @mappingmashups @stamen but #geowebchat was already all famous bc of @bricker talk @ #AAG2013

@spara Aug 20, 12:54pm we have screens for tweets related to @codeforamerica as well, neeners! #geowebchat

@alyssapwright Aug 20, 12:55pm @mappingmashups @stamen OMG. I take it all back. #geowebchat

@bethschechter Aug 20, 12:55pm @re_sieber, yes, totally intimidating. it kept me from joining for a long time. #geowebchat

@glenfarrelly Aug 20, 12:56pm Focus of #geowebchat appears to be creating maps. Are there other ways to create & share #geoweb info to reach different types of people?

@spara Aug 20, 12:57pm @alyssapwright @re_sieber Read @johannes_mono critique of hacker spaces textfiles.com/uploads/hackin… #geowebchat

@re_sieber Aug 20, 12:57pm .@bricker talk @ #AAG2013 Discussing concept of volunteered geographic information through a Tweetchat #geowebchat meridian.aag.org/callforpapers/…

@mappingmashups Aug 20, 12:57pm @bethschechter Important point: Don’t have to be an expert to start #maptime. Perhaps they’re best started by potential learners #geowebchat

@bethschechter Aug 20, 12:58pm intimidation re: hacker spaces and failures learning to code on my own is what inspired #maptime. #geowebchat

@lyzidiamond Aug 20, 12:58pm @mappingmashups @bethschechter This is why I want to start one! #geowebchat

@mappingmashups Aug 20, 12:58pm Well, we’re approaching the end of our #geowebchat. I encourage you all to keep following our blog: maptimesf.tumblr.com #geowebchat

@spara Aug 20, 12:59pm Great discussion everyone! #geowebchat

@bethschechter Aug 20, 12:59pm @mappingmashups it would be cool, for a mapmaking and sensing activity, to do some #maptime hacks at @noisebridge :) #onthelist #geowebchat

@geographerliz Aug 20, 1:00pm @mappingmashups learners still need leaders, & leaders should be open to teaching a variety of techniques & be learners #geowebchat

@mappingmashups Aug 20, 1:00pm As always, I’m looking for guest hosts and topic suggestions for future chats. Next #geowebchat is in two weeks: Sep 3. Topic TBD.

@JacqInTheBooks Aug 20, 1:00pm Thanks to all #geowebchat’ters today!

@re_sieber Aug 20, 1:00pm @glenfarrelly #geowebchat is more than maps but, in non-academic circles, it tends to attract map lovers #geowebchat

@bethschechter Aug 20, 1:01pm @geographerliz “learners still need leaders, & leaders should be open to teaching” = yes! also, mb 1 day students can teach too #geowebchat

@bethschechter Aug 20, 1:02pm signing off #geowebchat. Thanks everyone! cheers

@re_sieber Aug 20, 1:03pm .@mappingmashups Didn’t we use one #geowebchat to sort of bash the private sector? Do we now have to be careful now you’re @stamen? ;-)

@mappingmashups Aug 20, 1:03pm Thanks everybody! May a thousand #maptimes bloom! #geowebchat

@mappingmashups Aug 20, 1:03pm @re_sieber @stamen Bring it on! #geowebchat

@re_sieber Aug 20, 1:06pm @mappingmashups @stamen With that, great #geowebchat

@mappingmashups Aug 20, 1:08pm RT @spara: @re_sieber @mappingmashups @stamen It’s not bashing if it’s “fair and balanced” a la @SeanGorman #geowebchat

@USGSTNMRes Aug 20, 1:31pm @mappingmashups Just caught end of #geowebchat. Can #maptime go national? Also re Stamen: congrats!

#geowebchat transcript, 6 August 2013

By Alan | Published: August 6, 2013


@vtcraghead 6:47am Join us for a #geowebchat today at 3PM ET on “near-realtime satellite imagery” – Some background: bit.ly/13YdN8I

@vtcraghead 7:40am Just in time for today’s #geowebchat at 3PM ET, @brunosan drops some process details: @MapBox Satellite Live: PBS bit.ly/1ctcjMY

@vtcraghead 10:06am Tasking without a fax machine? We’ve got a lot to talk about at today’s #geowebchat – 3PM ET bit.ly/13YiShvw

@vtcraghead 11:02am In 1hr – 3PM ET – we’ll #geowebchat about the potential & pitfalls of near-realtime satellite imagery – wired.com/wiredscience/2…

@HeatherLeson 11:58am Time for #geowebchat about realtime satellite imagery

@vtcraghead 11:58am Hey everyone – we’ll be starting in a few minutes. The best way to tune into the conversation is here: qub.me/2D0vbe #geowebchat

@vtcraghead 11:59am Today we’ll be talking about the potential for near-realtime satellite imagery as new sensors and tools come online #geowebchat

@Moro_Cedric 12:00pm #crisismapping #digihums #openstreetmap #ushahidi RT @HeatherLeson: Time for #geowebchat about realtime satellite imagery

@vtcraghead 12:01pm I’ll be filling in for @mappingmashups – my background is in remote sensing and I formerly worked on the MODIS LC team . . . #geowebchat

@vtcraghead 12:01pm So this is a topic of great interest to me. #geowebchat

@vtcraghead 12:02pm First up for the committee: How would you folks use imagery from within 6hrs (@MapBox’s stated turnaround) of an event? #geowebchat

@vtcraghead 12:03pm And I’m curious about applications beyond the ones that have been mentioned in press like journalism and insurance. #geowebchat

@vtcraghead 12:04pm FYI here’s some background info I’ve been collecting. gist.github.com/wboykinm/61589… I’ll add to it as we go. #geowebchat

@erikfriesen 12:05pm @vtcraghead @MapBox It’s been “big” in the press lately… but it will obviously been a boon to endeavors like @SkyTruth #geowebchat

@AndrewShears 12:05pm .@vtcraghead Most obviously, for disaster events! @MapBox #geowebchat

@AndrewShears 12:07pm I would substantially assist EMs/EMAs to have quasi real-time flooding / damage data etc. #geowebchat

@vtcraghead 12:07pm .@AndrewShears The Disaster Charter has been live for awhile now – has anyone used imagery from it? qub.me/PLhII4 #geowebchat

@vtcraghead 12:08pm .@AndrewShears I mean does anyone have firsthand experience; I know it’s been used . . . #geowebchat

@AndrewShears 12:09pm .@vtcraghead (No, but I’ve now lost a few hundred future hours….. haha) #geowebchat

@rsimmon 12:09pm .@vtcraghead only to explain/illustrate after the fact earthobservatory.nasa.gov/NaturalHazards… #geowebchat

@vtcraghead 12:12pm I had access to imagery via the charter in the aftermath of hurricane Irene, but the turnaround was still 24 hours or so. #geowebchat

@AndrewShears 12:13pm Isn’t Disaster Charter more focused on larger events? I’m thinking local EMs/EMAs that aren’t a blip on that radar. #geowebchat

@vtcraghead 12:13pm I can think of problems that might have been alleviated by getting it faster, but then the holdup would have been on the ground. #geowebchat

@NeilGIS 12:13pm @vtcraghead Saw an old pic of Lake Memphremagog and spotted algae blooms. Not sure if tracking it would help, but now we could. #geowebchat

@vtcraghead 12:14pm @NeilGIS Good point – time series is another great strength here. #geowebchat

@Moro_Cedric 12:14pm @vtcraghead From within 6hrs, the best is to share the sat imagery in KML format on the web (ie @ushahidi @Crowdmap) #geowebchat

@vtcraghead 12:15pm RT @HeatherLeson: .@vtcraghead @AndrewShears A reference from the Simulation bit.ly/1eqqxuP #geowebchat

@AndrewShears 12:16pm I don’t think TweetChat is working right… #geowebchat

@vtcraghead 12:16pm .@HeatherLeson @AndrewShears And Haiti is obviously one of the benchmarks here. What actionable happened btwn hrs 6 and 24? #geowebchat

@mattmoehr 12:16pm Has anyone ever seen protest size estimation based on sat images? #geowebchat

@vtcraghead 12:17pm Hey, if Tweetchat isn’t working for anyone, give twitterfall a shot: qub.me/Ap0N0x #geowebchat

@jwass2000 12:18pm @vtcraghead Are there any privacy protections? Could I monitor neighbor’s yard for any suspicious digging or plants growing? #geowebchat

@erictheise 12:18pm @vtcraghead @AndrewShears tweetchat seems snappier to me, post-redesing, than it used to #geowebchat

@vtcraghead 12:18pm .@AndrewShears I believe that’s a big part of what @MapBox is marketing to. #geowebchat

@vtcraghead 12:19pm .@jwass2000 Just now wishing that @kpomfret was on this chat. I get the sense legal issues aren’t fully hammered out. #geowebchat

@AndrewShears 12:20pm @erictheise @vtcraghead May well be my connection. I’m out in the backwoods! #geowebchat

@HeatherLeson 12:20pm .@vtcraghead @AndrewShears #geowebchat More about Samoa – UN (2012) working to decrease that time (long read PDF) – phtpacific.org/sites/default/…

@vtcraghead 12:22pm .@AndrewShears @mattmoehr No, but the national park service has been on that since ’95 at least: .qub.me/Qe5n23 #geowebchat

@michael_d_gould 12:23pm You talking about DG first-look service? Esri and others will offer this. see ow.ly/nGEk9 starting around min 5. #geowebchat

@mattmoehr 12:24pm apparently that took like six days. i want (near) real-time estimates! #geowebchat @AndrewShears @vtcraghead

@vtcraghead 12:25pm .@michael_d_gould Indeed, which brings us to hardware vs. software; FirstLook has been around (since Irene at least) . . . #geowebchat

@AndrewShears 12:26pm .@mattmoehr @vtcraghead How politically charged (suddenly) would sat images be? Like Colin Powell’s Iraq pics…. #geowebchat

@NeilGIS 12:26pm @vtcraghead @HeatherLeson @AndrewShears Kinda what @mattmoehr said, could spot refugee camps and checkpoint lines as they form. #geowebchat

@vtcraghead 12:26pm .@michael_d_gould so why is DG working with ESRI, @MapBox and others on this? Have they given up on “full stack”? #geowebchat

@vtcraghead 12:27pm .@AndrewShears @mattmoehr I think the question of “authoritative view” would come up. #geowebchat

@Moro_Cedric 12:28pm @vtcraghead You can find Sat imagery in Real Time on VIRTUALOSUCC portal.gdacs.org/data/DataMapsa… #geowebchat @AndrewShears

@vtcraghead 12:28pm RT @kpomfret: New geospatial technologies r challenging traditional lines of what was OK and what was thought a privacy concern. #geowebchat

@michael_d_gould 12:28pm @vtcraghead uh, because services are the future. (?) #geowebchat

@vtcraghead 12:29pm .@AndrewShears @mattmoehr Like @wapo via @MapBox has one image but the NSA has another. Who does the public trust? #geowebchat

@HeatherLeson 12:29pm A friend from MIT shared this headcount tool: bitbucket.org/iv/headcounter… #geowebchat

@vtcraghead 12:30pm .@HeatherLeson Very cool. You can see it dodging around on a few of them, but looks pretty accurate. #geowebchat

@vtcraghead 12:31pm .@Moro_Cedric @AndrewShears Hoo boy. “VirtualOSOCC users can also request triggering of the International Charter” #geowebchat

@AndrewShears 12:31pm .@vtcraghead @mattmoehr and how long until the RNC has a satellite, DNC has one… suddenly science is politics a la polling #geowebchat

@mattmoehr 12:31pm #geowebchat MT @mattmoehr: .@vtcraghead @AndrewShears a debate re: “authority” in cartography? seems like nothing important changed, imo.

@mattmoehr 12:32pm @AndrewShears would they hire me? ;) #geowebchat

@vtcraghead 12:32pm .@mattmoehr @mattmoehr @AndrewShears Sure, but I don’t think it’s been tested yet in a real conflicting-imagery situation #geowebchat

@mattmoehr 12:33pm I for one feel totally inadequate in re: sat image processing. What are we teaching folks these day in GIS certificates? #geowebchat

@vtcraghead 12:33pm .@AndrewShears @mattmoehr That there is a frightening thought, though poll head counts seems vaguely legitimate. #geowebchat

@vtcraghead 12:35pm @michael_d_gould My sarcasm sensor is weak :) Why doesn’t DG provide the service? (They do, just not compellingly it seems). #geowebchat

@HeatherLeson 12:35pm Barriers to getting imagery have been lowered due to the some work of @Digihums @hotosm @MapBox. #geowebchat (eg. digitalhumanitarians.com/where-to-volun…)

@wsvekla 12:35pm @AndrewShears @vtcraghead consider tension between remote sensing (observing from afar) and sensors on the ground, in devices. #geowebchat

@HeatherLeson 12:36pm .@mattmoehr You could volunteer & learn with one of the @Digihums teams – digitalhumanitarians.com/where-to-volun… #geowebchat

@vtcraghead 12:36pm .@wsvekla @AndrewShears Project idea: link a video feed of every google glass onsite w/ realtime sat views :) #geowebchat

@vtcraghead 12:38pm So there’s a bit of a convo about business: What do DigitalGlobe and Astrium get out of this? Are they ceding markets? #geowebchat

@michael_d_gould 12:38pm Human Rights Watch is also looking for help IDing possible conflict frm chatter and imagery. #geowebchat

@AndrewShears 12:38pm What about implications of this data for civil unrest, revolution, etc? Easier to suppress? Would Tahrir have been different? #geowebchat

@NeilGIS 12:39pm How quickly can go from imagery to data that matters? Will this be faster than ground reports for road washouts for example? #geowebchat

@michael_d_gould 12:39pm @vtcraghead business in general is moving away from download and keep, to subscribe and use. #geowebchat

@vtcraghead 12:40pm RT @wsvekla: valuable for post-disaster recon, this was kind of approximated with linking of aerial photos with ground truth #geowebchat

@AndrewShears 12:40pm .@vtcraghead @wsvekla With that, you could reasonably 3d render the environment in (near) real-time. #creepy #geowebchat

@GPSBaby 12:41pm #geowebchat a key issue isn’t about speed of release its also about avoiding duplicated production – NGA/UN/NMA/OSM/MAPACTION ….

@vtcraghead 12:42pm .@NeilGIS Good point, and this rubs up against the work that FEMA & NGA do in the aftermath of a domestic disaster. #geowebchat

@spara 12:42pm Companies to watch in this space:
planet-labs.com
skyboximaging.com
#geowebchat

@AndrewShears 12:42pm .@michael_d_gould @vtcraghead ….at expense to customers/clients (nevermind rural folks with poor connect). See newest SimCity. #geowebchat

@vtcraghead 12:42pm .@GPSBaby But the NGA is using different sensors :) #geowebchat

@razsc 12:42pm With almost real time sat imagery, what do we do with earlier versions. Will we need a git style archive for sat imagery? #geowebchat

@vtcraghead 12:43pm .@razsc Whoa – tiled git. *furiously takes notes* #geowebchat

@vtcraghead 12:44pm .@AndrewShears @spara Yeah – you don’t hire Frank Warmerdam without being serious. #geowebchat

@erikfriesen 12:46pm @razsc geogit for raster data is an interesting thought. #geowebchat

@vtcraghead 12:47pm So the satellite world is suddenly moving really fast – where does Landsat 8 fit in? or NASA’s EOS program generally? #geowebchat

@GPSBaby 12:47pm @vtcraghead not just about inputs its about outputs and too much duplication confuses use and authority ..#geowebchat

@wsvekla 12:47pm ok so side topic: what’s the current state of automated feature extraction? with vis spec, still talking human interpret right? #geowebchat

@spara 12:47pm @vtcraghead @AndrewShears Word from foocamp is that Planet Lab is building a microsat constellation #geowebchat

@vtcraghead 12:48pm .@wsvekla The @MapBox satellite team is doing some admirable work streamlining processing between sensors . . . #geowebchat

@michael_d_gould 12:48pm @AndrewShears expense? everything has an expense, and there are myriad ways to pay. #geowebchat

@vtcraghead 12:49pm .@wsvekla But to my knowledge we’re still looking at OBIA backed by human rules qub.me/42IUFT #geowebchat

@razsc 12:49pm @wsvekla from my experience automated feature extraction works well with text, visual is still very difficult #geowebchat

@wsvekla 12:49pm .@vtcraghead is that more about traditional applications of various bands, etc? veg cover, etc? #geowebchat

@vruba 12:49pm @vtcraghead I think that, among many other uses, EOS will remain indispensable as a free, high-reliability baseline. #geowebchat

@vtcraghead 12:50pm .@michael_d_gould @AndrewShears To my point about NASA, does it make sense for gov to pay for this sort of thing? #geowebchat

@michael_d_gould 12:50pm @AndrewShears what about newest SimCity? #geowebchat

@vtcraghead 12:51pm .@vruba The data consistency is important from the temporal perspective, but 250m pixels look antiquated now. #geowebchat

@rsimmon 12:51pm .@vtcraghead What they were designed for–long-term, global, calibrated measurements #geowebchat

@wsvekla 12:51pm @razsc yeah, my impression, too #geowebchat

@vruba 12:52pm @vtcraghead For a Tahrir Square situation, definitely. But for a news story about the weather, ge.ssec.wisc.edu/modis-today/in… is great. #geowebchat

@rsimmon 12:53pm @vtcraghead @vruba antiquated? not for global change: aerosols, ocean color, cloud properties #geowebchat

@rsimmon 12:54pm @vtcraghead BTW, I’m sure NASA would do high res if they could–forbidden in the Land Remote Sensing act #geowebchat

@vtcraghead 12:54pm .@rsimmon @vruba Even as processing power increases? Wouldn’t a 5m GCM be useful? #geowebchat

@GPSBaby 12:54pm The Chinese have great ambition with their new global landcover map and higher resolution satellites #geowebchat

@vruba 12:54pm @vtcraghead Plus, even for human-driven news, often you don’t know what you want until later — you need the “before” picture. #geowebchat

@vtcraghead 12:55pm .@rsimmon Good to know – is there any reading on how commercial providers got around that? #geowebchat

@vruba 12:55pm @vtcraghead @rsimmon I think 5 m would be false precision for GCM. That’s below the scale of normal annual change! #geowebchat

@vtcraghead 12:57pm .@vruba @rsimmon Awww . . . no butterfly effect? :) #geowebchat

@rsimmon 12:57pm @vtcraghead DoD–they paid for Ikonos, OrbView, and QuickBird. #geowebchat

@rsimmon 12:58pm @vtcraghead Google “EnhancedView” & “contract” for specifics (half up front, commitment to buy data. *Lots* of data.) #geowebchat

@vtcraghead 12:58pm .@rsimmon The windy roads of defense and science politics bedraggle me. #geowebchat

@vtcraghead 12:59pm Last Q as we wind down: Is there any downside to a split between satellite hardware & image-delivery services? #geowebchat

@vruba 12:59pm @vtcraghead @rsimmon I think EOS’s quality-not-quantity, collect-it-all approach fills a vital niche & is good for business. #geowebchat

@vtcraghead 1:05pm Okay, thanks everyone for participating – I’ve added the links that came up to the reading list: qub.me/6F21Fd #geowebchat

@vtcraghead 1:06pm Tune in on August 20th at the same time for the return of @mappingmashups! #geowebchat

@HeatherLeson 1:20pm @vtcraghead thanks for hosting! #geowebchat
