>GPS isn't anywhere near accurate enough for that

For what? I remind you that we're talking about a Wikipedia filter. Wikipedia entries are so coarse grained with respect to position that you don't even need GPS-level accuracy. (Not to mention it can correct itself with the help of the built-in maps, e.g assume you walk in the sidewalk and not 4 meters across inside the buildings etc).

"That place is the Brooklyn Bridge, that thing down the road is the Katz delicatessen, further down is CBGB, stuff like that".

Where's the need for "more than a few meters accuracy"? If it can show me info of the nearby stuff (5-10-20 meters away) on my Glasses, it's perfectly good.

It doesn't have to super-impose it when I look at the specific building (that would be stupid anyway, cause it would necessitate me to keep looking straight at the building to see the info).
