[GRASSLIST:1407] Merging gtopo30 DEM raster files

[ECIS Mail]

ALL

I am new to Grass but have followed it's development for some time.  I
recently installed Grass V5b10 and there are a few problems which I have
worked around, usually by using the command line instead of the Tcltk
interface, which is otherwise rather nicely done. Kudos to all developers
and contributors.

I hope to be a contributor someday as well but for now I am trying to learn
about Grass's functionality.  As a meteorologist by profession and an
applications integration computer geek by choice I am trying to adapt Grass
to the operational end of meteorology.  My immediate problem is that I need
a contiguous "Grass" location definition based on 8 separate panels of the
GTOPO30 DEM raster data.  I have learned how to overlay the 8 panels into a
Grass monitor display, but I have not found an appropriate function to
output the new overlay dataset into a single 1KM raster DEM file.

I have found a reference to d.savescreen in the manual page off the internet
location, but there is no such command in the bin installation I have.  I am
not even sure this command would preserve the original resolution.

To some it up, I need to be pointed in the direction to the tools that will
perform this task.  Can anyone help?  I run Grass on a x86 box under Redhat
Linux Ver 7.

TIA
