#geowebchat transcript, 20 May 2014: navigation using crowdsourced geodata


@mappingmashups May 19, 11:26am Next #geowebchat: navigation w/ crowdsourced geodata! Join the chat Tue May 20 at 12pm PDT. Further reading: stevecoast.com/2014/05/19/why… Pls RT!

@mappingmashups May 19, 12:59pm Here’s another take on crowdsourced (indoor) navigation for our #geowebchat tomorrow: bits.blogs.nytimes.com/2014/05/18/map…

@erictheise May 20, 11:08am TGIS(tructured)T(uesday): @revsnakeens’s #TheNewEdge wmbr.org/WMBR_live_128…. …, #SF siren test, #geowebchat re navigation w/crowdsourced data

@mappingmashups May 20, 12:00pm Welcome to #geowebchat everyone. We’re discussing navigation using crowdsourced geodata (like #openstreetmap)!

@mappingmashups May 20, 12:02pm This week there’s been some big news with @Telenav launching a new navigation SDK based on OSM: techcrunch.com/2014/05/19/tel… #geowebchat

@mappingmashups May 20, 12:02pm According to @SteveC, founder of openstreetmap, this means OSM is now finally ready for prime time: stevecoast.com/2014/05/19/why… #geowebchat

@mappingmashups May 20, 12:03pm Welcome @mvexel! Yeah, tweetchat.com is a great site for following along with #geowebchat. Who else is joining us?

@mappingmashups May 20, 12:04pm So, first question for the group: have you tried any navigation apps using OSM data? What were your experiences? #geowebchat

@sidewalkballet May 20, 12:04pm @mappingmashups I’m lurking; may have some comments from the peanut gallery #geowebchat

@jwass2000 May 20, 12:04pm @mappingmashups @SteveC @mvexel Would love to know what criteria was needed/met to deem OSM “ready” #geowebchat

@mappingmashups May 20, 12:05pm Also, we can make comparisons with apps like @waze for crowdsourced navigation. #geowebchat

@mvexel May 20, 12:06pm ‘ready’ is when it gets almost everyone from A to B reliably #geowebchat

@Fischbob May 20, 12:07pm @sidewalkballet @mappingmashups I’m also here – primarily to listen! Haven’t tried any OSM navigation apps – yet! #geowebchat

@mvexel May 20, 12:07pm We tested with a ton of reference routes as well as spent countless hours drive testing #geowebchat

@neogeografen May 20, 12:08pm Used #osmand bicycle off-line navigation works fine in rural areas #geowebchat (Denmark tested) – however like most off-line POIs search

@erictheise May 20, 12:08pm i’m here, not #winningatlife, but eager to see what @mvexel & others have to say. #geowebchat

@petzlux May 20, 12:09pm #geowebchat used navdroyd years ago, worked well in 2011 in romania roadtrip! Ubfortunately got bought by cloudmade who promptly stopped dev

@jwass2000 May 20, 12:09pm @mvexel Right, how to define “reliably”? Missing one-ways, bad speed info, etc. Weird routes can come out which = upset users #geowebchat

@mappingmashups May 20, 12:09pm @neogeografen Interesting, in some ways bike navigation might be easier (?) because turn restrictions are less important… ? #geowebchat

@mappingmashups May 20, 12:10pm @neogeografen …but of course bike navigation also needs a lot of special metadata that cars don’t need. #geowebchat

@jwass2000 May 20, 12:11pm @mvexel OK, we’ve looked at MapquestOpen and it can suggest routes 30% slower than Google. Would love to cmp to Telenav #geowebchat

@mappingmashups May 20, 12:12pm And at the last #editathon in SF @accessgeo was working on adding features for accessible pedestrian navigation… #geowebchat

@ShereenaDyer May 20, 12:12pm Hello! I am new and dropping in to listen during lunch. I have used @waze before. #geowebchat

@mappingmashups May 20, 12:13pm RT @neogeografen: hard work bike-nav to work in major cities – more rules – oneway for cars – often it’s allow bikes both ways #geowebchat

@mappingmashups May 20, 12:14pm RT @neogeografen: So fx Copenhagen you have to add more meta-data (tags) to get bike-navi to work well. #geowebchat

@erictheise May 20, 12:16pm i’m curious about a lot of things on this topic, but the main one is user feedback on faulty routes and data. @mvexel? #geowebchat

@mvexel May 20, 12:16pm reliabilty is about completeness of the data, being able to route across the entire network, no unsafe routes #geowebchat

@cartocalypse May 20, 12:17pm first #geowebchat i happen to catch live. :) i use komoot.de/plan a lot for foot/bike routing, sadly online only. very nice results

@mvexel May 20, 12:18pm @erictheise we will get active (reported) and passive (collected) feedback – both require different approaches #geowebchat

@erictheise May 20, 12:19pm so, @mvexel, passive will compare actual routes w/recommended routes and active… what’s the mechanism? #geowebchat

@mvexel May 20, 12:19pm my first #geowebchat in a long long while – thought I should not be missing this one :)

@erictheise May 20, 12:21pm we all remember apple map/routing horror stories such as people driving across active airport runways because they were told to. #geowebchat

@mvexel May 20, 12:22pm @erictheise active: people tapping ‘report error’ – how we’ll process that, not sure yet. maproulette? OSM notes? depends… #geowebchat

@mvexel May 20, 12:23pm …on actionability mostly – can we actually do anything with the feedback #geowebchat

@erictheise May 20, 12:26pm tiered feedback is needed, w/auth? continuum of people from “thumbs down” to superuser who’ll fire up jsom & repair a relation #geowebchat

@mappingmashups May 20, 12:28pm (Sorry #geowebchat, AFK…)

@betsymason May 20, 12:29pm Is telenav/scout/skobbler the biggest entity/app using OSM? #geowebchat

@mvexel May 20, 12:29pm @erictheise the superuser idea I think can be pretty powerful. like data stewards. #geowebchat

@erictheise May 20, 12:31pm also intrigued by @Mapbox’s language about alt metrics: max serendipity/scenery/curves, min climb/fuel gigaom.com/2014/04/21/nav… #geowebchat

@jwass2000 May 20, 12:31pm Real-time traffic big part of mainstream adoption. Does attaching real-time speed info to OSM trigger sharealike? #geowebchat

@mvexel May 20, 12:33pm @jwass2000 I don’t think it would #ianal #geowebchat

@spara May 20, 12:34pm New question. Other than OSM, is there any other open source effort that supports door-to-door routing? #geowebchat

@mvexel May 20, 12:35pm @spara both open source & open data? I don’t know of one. #geowebchat

@spara May 20, 12:37pm @mvexel Yes open data, I’ve been looking for parcel/door level solutions. #geowebchat

@oeon May 20, 12:37pm Has anyone heard of any projects using OSM data/routing for emergency dispatching/response? #geowebchat

@allafarce May 20, 12:38pm @spara @mvexel You probably already know, but a variety of different routing projects are here: wiki.openstreetmap.org/wiki/Routing#D… #geowebchat

@vtcraghead May 20, 12:38pm @oeon Not that I’ve heard of, but it’s one of the “what-ifs” of @hotosm #geowebchat

@mvexel May 20, 12:39pm @oeon I saw a system in NL that used OSM basemaps, but not OSM as routing / geocoding back end. #geowebchat

@oeon May 20, 12:40pm @vtcraghead @mvexel I would love to see some disruption in the Computer Aided Dispatching software realm #geowebchat

@jwass2000 May 20, 12:40pm @mvexel Wow. I’m no fan of sharealike but am surprised to hear that #geowebchat

@mvexel May 20, 12:41pm @jwass2000 I am actually a fan of share-alike, but we’d have to get the lawyers in here to have that discussion. #geowebchat

@erictheise May 20, 12:41pm .@jwass2000, i recall presentation at @sotmus pdx went into the thinking re sharealike. ryan peterson’s? stateofthemap.us/2012/#schedule… #geowebchat

@spara May 20, 12:42pm @mvexel @oeon So what would it take for an open data solution to be used for emergency response? #geowebchat

@vtcraghead May 20, 12:43pm @oeon @mvexel pgRouting + OSM + radios, pretty much. Also, institutional will :) #geowebchat

@mvexel May 20, 12:43pm @jwass2000 There’s already way too much smoke around ODbl / SA and nobody’s seen any fires. #geowebchat

@mvexel May 20, 12:45pm I’m going to have to sign off, thanks for discussion everyone. Happy to discuss more offline. #geowebchat

@cartocalypse May 20, 12:46pm @oeon #geowebchat i know of several voluntary fire brigades (in germany) who at least planned to map fire hydrants in osm for that

@erictheise May 20, 12:48pm hollywood thriller; bad guys inject bad data into osm, count to ten, commit crime, good guys pursuing get routed to #timbuktu. #geowebchat

@mappingmashups May 20, 12:55pm RT @neogeografen: If any comes to #sotmeu in Germany next month a guy from Copenhagen will tell about bike-navi project for Cph. #geowebchat

@mappingmashups May 20, 12:56pm Thanks for the great discussion everybody. We’re approaching the end of our hour for #geowebchat. Any final thoughts?

@erictheise May 20, 12:57pm i am available for script consulting, all you favoriters, only stipulation is that there be a role in which we cast tom hughes #geowebchat

@GeoPenny May 20, 12:57pm sorry to miss #geowebchat will have to keep my eye out 4 future ones

@mappingmashups May 20, 12:58pm @GeoPenny Thanks for dropping in at the end! #geowebchat happens every 1st and 3rd Tuesday of the month at the same time.

@mappingmashups May 20, 12:59pm Next #geowebchat will be June 3 at the same time (12pm PDT). Topic suggestions and guest hosts welcome!

@mappingmashups May 20, 1:00pm Today’s #geowebchat transcript will be posted at mappingmashups.net shortly. All previous chats are archived there, too.

@erictheise May 20, 1:01pm @mappingmashups, remind @GeoPenny & others about the subscribable webcal calendar! super-useful #geowebchat

@mappingmashups May 20, 1:04pm Oh, yeah: subscribe to the #geowebchat webcal here: webcal://bit.ly/geowebchatcal. Updated w/ upcoming topics as soon as I figure them out!
