This is interesting, now if only they had 3d topography maps.

I'm building a GPS tracker that I can take on hikes and will store coordinates and altitude to an SD card so I can generate 3d models of the path I take or overlay with 3d maps.

USGS offers digital elevation maps as rasters [1]. There is also the 10-meter SRTM data from shuttle SAR [2]. Combining elevation with the USGS topo maps visually for 3D is an interesting image processing task.

What hardware are you using in your tracker?
