Has anyone managed to write a routine to read in the USGS' 7.5 minute
DEM files (description at
http://edc.usgs.gov/glis/hyper/guide/usgs_dem)? I have done so for the
NMA 3 arc-second DEM's, but the 7.5 minute series are more complicated
due to the fact that they are defined on UTM rather than lat/long
coordinates, and thus have a variable number of profiles per file and
points per profile. Any pointers greatly appreciated -
