I refined the area for which I need the DEM and used g.remove on the two huge data files in my previous thread. Now r.in.arc finds missing lines in the hdr.adf source file.
All data comes from http://ned.usgs.gov/ and the seemless National Elevation Dataset. I specified a region in DMS: N 49:15, S 48:30, W -119.15, E -118:00 and downloaded the extracted file. Same process as with the two former files except those were outlined on the displayed map rather than specified by lat/long. When I use the GUI to import the raster map using r.in.arc I get these errors: r.in.arc --o --verb input=/home/rshepard/GIS/data/Washington/elevation/NED_32789676/ned_32789676/hdr.adf out=elev titl=DEM Illegal line in header GRID1.2 "yllcorner" field missing from header "xllcorner" field missing from header "nrows" field missing from header "ncols" field missing from header "cellsize" field missing from header "nodata_value" field missing from header ERROR: Can't get cell header There's a text data file that contains the missing information (output_parameters.txt): Raster Download Information Number of columns: 4500 Number of rows: 2700 Resolution in x direction: 0.000277777777796473 Degree Resolution in y direction: 0.000277777777796473 Degree Coordinate system ID Native: 4269 Top edge Native: 49.2500000000968 Degree Bottom edge Native: 48.5000000000464 Degree Left edge Native: -119.249999999684 Degree Right edge Native: -117.9999999996 Degree Coordinate system ID WGS84: 4326 Top edge WGS84: 49.2500000000968 Degree Bottom edge WGS84: 48.5000000000464 Degree Left edge WGS84: -119.249999999684 Degree Right edge WGS84: -117.9999999996 Degree I assume that the problem is on my end because in the past I've imported data from the seamless map into GRASS. I'm out of ideas what to do since I repeated the extraction with the same lack of success.
