The output files from ps.map are huge: the .ps is about 665M and the .pdf
is 9.9M. Way too large!
The DEM is at 10m cell size. 'g.region -p' produces:
projection: 99 (Lambert Conformal Conic)
zone: 0
datum: nad83
ellipsoid: grs80
north: 1334419.15160578
south: 1279151.24118496
west: 769192.92822895
east: 819255.92362222
nsres: 7.49700358
ewres: 3.37898187
rows: 7372
cols: 14816
cells: 109223552
This has fewer cells than the source raster DEM covering a larger region
(18,724 rows, 24,657 columns, 461,677,668 cells).
Should I change the nsres and ewres to 10.0? Should I change the number of
rows and columns? Your advice is needed to produce high quality output at
reasonable .pdf size.
