Looks cool. I am going to try to see if I can get the map for the hill behind my house.

Man, it's too bad a bunch of the USGS quads they are using are really out of date. there are a few that the USGS has not updated in years, but  whoever put this map source together didn't use the most recent available.

I like the USFS maps better than the USGS.  They appear to have more info.

 You haven't traveled in any 3rd world countries lately, have you? At least the USGS hypsography is pretty accurate, which is more than I can say for a lot of other countries (including some supposedly 1st and 2nd world countries I have been in).

Roads and trails are a serious problem, since they change so rapidly (ok, so here in Calif, it's just that the roads deteriorate so rapidly and haven't been worked on in so many years that, although the alignments are ok, some of the "freeways" should be marked as effectively "unpaved").

Google topo isn't very good either. You would think that with the detailed sat photos available and with the automated stereo topography machines available, they could update faster. Unless you are well-trained in photo-interpretation, Google Earth and Google Maps aren't a lot of help either.

Worst part is that a lot of the computerized and on-line topo mapping programs are vector maps based on the hypsographic grid, which has 1km point spacing in some areas, and few areas with finer than 100 m spacing.

Does anyone know where you can get the center line data for the AT? 

postholer.com/gmap/  uses it to make their maps.

Ok, I just saw that this site has a Forest Service layer. That is awesome.
