Nat,
I guess I am looking for land only.
Regarding resolution: I am curious because the speaker talked about how
after the psunami, the UN did not have good maps (particularly digital)
which they needed so as to route aide. The maps they had were too
course or very out of date. Now, with google maps, etc., people are
uploading content so as to produce more accurate maps that available to
everyone.
thanks,

Um, are we including inhabited land surface only? Or do we need to
geocode ice caps and open ocean? If the ocean is included, are we
judging ocean floor or water surface? And what IS a geocodable level?
I've seen range geocoding out there that's based on pretty loose data...
so, 1m resolution? 10m?
