Thanks Markus,
I had check to see that the region extents matched the area I wanted
to map, but I didn't check the resolution. I see now that I have
many more rows and columns than I need.
I'll make and adjustment, and try again.

Hi,
I've run into a problem using ps.map. I'm trying to output maps
that have
printed successfully before. The map files overlay several vector
layers on
a fairly large raster image. In the past, the eps files were
created in
about a minute, and were about 120 mb in size. Now, the images
take about
20 minutes to create, are over 2 gb in size, and will not open.
ps.map reads raster maps using the current region settings. Try to
adjust the region resolution to reduce the number of cells in the
current region. You can calculate the minimum required region
resolution from the map dimensions (e.g. paper size minus borders for
East-West) and desired dpi. The number of rows and columns in the
current region should correspond to the number of dots that fit into
the printed or pdf map.
HTH,

The problem seems to be with the raster layer. If I eliminate it,
the
output is normal. When I add it back, I get corrupt output
files. The
layer does display properly in GRASS.
It there a way to tell whether the problem is in the raster layer,
or in the
eps processing routines? I'm using GRASS 6.3.0-2 (Lorenzo's
binary) on OS
10.4.11.
Thanks in advance,
Dave
