A little more sense of worthwhile direction would probably be helpful
for most of us.
I'm thinking of AR as a new projection. A map is usually a heads down
aerial view of data on earth, described as lines, dots, blobs, and
words. geodata on a surface. Handheld AR is a heads-up cinematic view
(flipped 90degrees vertical) of geodata What if a user could hold up
the viewfinder on a mobile a see the same geodata, in a new view, the
same parameters for polygon of cartographic meaning across the street.
The data about location and meanings are all there, but the
visualization is different. What kind of exisiting 2d geospatial data
should be visible in this new view? How to describe those views? in
KML? Information about places: infrastructure, environments, cultures,
commerce, industry, populations, health, crime, policies, facilities,
agencies, services, attractions? I simply want to hold up a handset
viewer and and turn on the filters to select layered views on the real
world not a flattened aerial map view. Maybe it's a bad idea to think
about viewing legacy geodata in AR. (?) I'm not sure.
Next gen handsets, by using fused data from gps and compasses, will
certainly know where they are ( lat/lon/elevation) accurately enought to
render at least crude geo AR. Meanwhile Nokia, Microsoft and Google and
others are all racing to offer precise positioning by matching handset
views with stored point clouds of processed 3D models, that they and
others are building. Earthmine in Berkeley, by the way, is offering free
access to testsets of 3D imagery, where every pixel has a restful uri,
has 3d coordinates, with 2mm accuracy
This will all still take a few years to mature, for people to create a
critical mass of 3D geodata, We're just in the early freak artist
stage of all this, AR videogames, etc. I hope. so there is probably
enough time to thinking about things to do with standard 3d AR views of
geodata.
Or we can just let google build he whole thing with KML.
That said, of course my forthcoming AR app for iPhone is bound to sell
a million copies ; > )
Cheers,

wow! I didn't expect many replies from busy people to my questions
about handheld viewfinder AR views of 3d geodata, but given the
staggering potential for AR as a radical new kind of mapping is
mind-boggling, I am a bit surprised that in the 24 hours of my post,
this normally verbose community has nothing to say. Aside from a
mild suggestion by Sean Gillies of "democratizated service-oriented
architectures of curation" no one else offered 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
viewfinder AR 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, to experiment
( ) d. Already into AR 3dgeo, not saying much about what we're doing
until it's ready.
( ) e. Have some ideas a bout AR 3dgeo, but am too fr*&#n busy to
respond to random listserv e-mails :-)
whatever. AR looks like a fun, open frontier in both geoscience and
geohacking, let's hope the foss gang gets there before goog & apple
own it.

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 engage in a little thought experiment about handheld
views of 3d geodata:
Context: The realtime tweetsphere http://bit.ly/rZncR and
youtubesphere http://bit.ly/UwQ3u are alive with news of handheld
AR, [agumented reality] 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 3d web 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 to see 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 signal strength, visible sensor net readings of air quality..
visible entry into another 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
equivelant client down to a cloudwide RESTful deep geocoded web of
linked 3D geodata?
Just curious, what people are thinking these days . . .
Mike
