Lack of data.1."Bad PrecisionWe can safely anticipate precise positioning is on the way to being solved, at least for outdoor urban apps. Google, Microsoft and Nokia have all announced they are work on precise positioning of handsets, by matching significant points in images with a stored datablase of 3D points. A few weeks ago, at the GML Geoweb conference in Vancouver, Michael Jones, from Google showed a 3D model google guys mashed up from flickr images using something like MS photosynth. Aside from Earthmine, which I already mentioned, I know of several unnanced projects to similar things, with much greater precision.In any case, A lot of AR will work fine simply using a GPS and compass. 2. "Lack of Data"What's new?! In 2003 when Joshua Schachter launched geowanking, there was almost no geocoded web data, aside from his home grown GeoURL. That didn't stop anyone on this list from experimenting. About the same time Chris Goad, Jo Walsh, Dan Brickley and others created a geo RDF, Chris implemented a working demo for us, at IFTF.org of geoRDF web annotations with integrated vector shapefiles from the National Park Service. This demo, in '03 or '04 was the first full blown demo of a geospatial web.Since then, People on the Geowanking list including, Mikel Maron, Andrew Turner, Alan Doyle, Raj Singh, Sean Gillies, Chris Schmidt, Carl Reed, Ron Lake and others, designed and implemented GeoRSS which has resulted in countless geocoded points, and sincel then, as we all know google has promulgated KML which has resulted in milions more geocoded points.Summary: It's time to start again. We need a simple way of geocoding augmented reality, and many ways of processing searching and and viewing geo AR.Historically, the geowanking community, has been the crucible of innovation for a geospatial web. ( see above) Maybe five years ago, everyone was out on the street, and hungry enough to build a totally new ways to experience spatial data., and maybe now everyone is gainfully employed and too distracted to launch a second perhaps even more interesting spatial web, viewable throught the viewfinders of our phones, and later on, perhaps in eyeglasses. If that's the case, then we can all just sit back and let google build the whole thing without us. Clearly their latest UI implementations in Streetview are part way there. see: http://google-latlong.blogspot.com/2009/07/zoom-photo-navigation-in-street-view.html~ MikeWe experimented with indoor enviromnents based on our Indoor WPS approach and server (see http://gis.hsr.ch/wiki/IndoorWPS). These are some screenshots of an Android prototype: http://dev.ifs.hsr.ch/indoorguide4android/wiki/WebDocu . So according to Mikes explanatory selection my answer is:(X) d. Already into AR 3dgeo, not saying much about what we're doing until it's ready.Yours, Stefan P.S. BTW I also was expecting bit more of response about my recent thread about "Better auto-discovery in the Geo-Web through "see" and "see also" links?" since I thought geo-search technology could be of interest to geowankers. I still did'nt give up. 2009/8/4 Mike Liebhold <[email protected]>:wow! I didn't expect many replies from busy people to my questions abouthandheld viewfinder AR views of 3d geodata, but given the staggeringpotential for AR as a radical new kind of mapping is mind-boggling, I am abit surprised that in the 24 hours of my post, this normally verbosecommunity has nothing to say. Aside from a mild suggestion by Sean Gillies of "democratizated service-oriented architectures of curation" no one elseoffered any thoughts at all about viewfinder AR views of 3d geodata. We can only guess why the silence:( ) a. Mostly into map views of geodata, not very interested in viewfinderAR 3d geo. ( ) b. AR 3dgeo is interesting, but haven't thought much about it.( ) c. Have some ideas about AR 3dgeo, looking into it, waiting for apis, toexperiment( ) d. Already into AR 3dgeo, not saying much about what we're doing untilit's ready.( ) e. Have some ideas a bout AR 3dgeo, but am too fr*&#n busy to respondto random listserv e-mails :-) whatever. AR looks like a fun, open frontier in both geoscience andgeohacking, let's hope the foss gang gets there before goog & apple own it.- Mike Mike Liebhold wrote:This is a humble request for geowanker mappers and geocoding web artists alike to join me to quiet our 2d cartographic minds for a minute to engagein a little thought experiment about handheld views of 3d geodata:Context: The realtime tweetsphere http://bit.ly/rZncR and youtubespherehttp://bit.ly/UwQ3u are alive with news of handheld AR, [agumentedreality] capabilities & apps, and services. Besides layar and wikitude on android, there are already a number cool hacks for jailbroken iPhones, and veiled confirmations from apple that the next rev. of the iphone os dev release for the 3gs will support AR app integration of gps, compass, and graphic overlay of video cam views. The viewfinder is becoming a new AR 3dweb browser. AR is here, if not today, tomorrow, but i suspect our geosphere is not ready. questions for fellow geowankers:1. What kind of geodata and locative media will be most useful or fun tosee geopositioned in 3d in our handheld viewfinders.e.g. floating labels of things, animated directions, emergency alerts,news and ads to filter, cartoon games, visible clouds of wifi signalstrength, visible sensor net readings of air quality.. visible entry intoanother colored polygon of cartographic meaning, etc. 2. How will we search, view, create, and serve open 3d AR geodata? 3. What is the prospective FOSS stack for 3dAR geoservices? e.g. starting at the top with a 3D firefox or open layers equivelantclient down to a cloudwide RESTful deep geocoded web of linked 3D geodata?Just curious, what people are thinking these days . . .
