[GRASS-user] National Elevation Data

[Kurt Springs]

Hi Folks,

I downloaded a National Elevation Dataset layer from the USGS.  I haven't any idea of how to import it as a raster layer.  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?
