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.
