Even with the new USGS NED server, you may still have to turn the DEM files from a supplied format (like flt) to tif for DEM2TOPO. I used a batch file I got at the USGS, which in turn requires and installation of the gdal utilities. Much of the instructions were written when the USGS seamless server supplied tif (Geotiff)-- that server is mainly gone.
I'm using this process for areas outside the USA, where the are no good topo maps, or the available maps are off. I've even found places in Nevada where the available garmin-compatible maps are off. I'm also interested in some of the newer data, which may resolve some massive errors in the USGS database.
Where are the flt files? In the group of files that I downloaded, the one large file (465MB) has an adf extension.
Thanks
