[GRASS-user] National Elevation Data

[John C. Tull]

Hi Kurt,

I concur with William. Part of my workflow on the seamless server is to always go into the options and make any downloads tgz's. Otherwise, you get a mess that is a challenge to untangle.

This requires a few extra mouse clicks, but it makes a big difference in the end.

Good luck,
John

Its got several types of files:  .dir, .dat, .nit, .aux, .adf, as well as some esri metadata files (.dbf, .prj, .shp, shx).  Can anyone tell me which file is the one I want to try to import as a raster file?
