Dave,
Postscript is probably still the best choice of output if you will
be printing the file. If it's just going to be displayed on a
computer screen, then a raster format should suffice.Here's one method I've used occasionally which I like because I
can log in from home, create a map and an image file, and download
it in some format (e.g., gif) that I can display on my PC at home.If you just want to convert a raster map, use r.out.ppm or r.out.tiff.
Then use image tools to convert to your favorite raster format.If you have vector & sites & rasters that you want to display and
convert, You can use the
CELL display monitor to write to a GRASS raster file named D_cell,
(d.mon start=CELL; d.rast, d.vect, etc; d.mon stop=CELL)
then export the image using r.out.ppm or r.out.tiff
(g.region rast=D_cell; r.out.ppm D_cell)
and convert the ppm file to whatever format you want using your favorite
image conversion tools.r.out.ppm is a contributed program available from ftp
moon.cecer.army.mil in grass/incoming.
The size and resolution of your image will depend on :
1) the "display" size of the D_cell file, set by using the environment
variables GRASS_WIDTH and GRASS_HEIGHT
2) the region set by g.region at the time you use d.rast, d.vect, etc.
2) the region set by g.region at the time you use r.out.ppm
(generally, use g.region rast=D_cell)you should be aware that resampling of the data can happen at each of
these stages. For best results with this method, try this:
g.region rast=<rasterfile> -p
setenv GRASS_WIDTH <cols+1>
setenv GRASS_HEIGHT <rows+1>
d.mon start=CELL
d.rast <rasterfile>
d.vect <vectorfile>...
d.mon stop=CELL
g.region rast=D_cell
r.out.ppm D_cell [out=outfile.ppm]Hope this helps!
