Dear Casey,
everybody is on holiday, I assume, otherwise you would have been
overwhelmed with messages where to locate the existing tutorials (or am I
a bit too optimistic?). Usually, anything that is available can be found
on the anonymous GRASS ftp-site at moon.cecer.army.mil. When you go
through the directories, you'll notice some tutorials, the very contents
of which I don't know - I never used them, in fact. There used to be a
GRASS Beginner's Manual by Martijn van Leusen - I suppose he is on
holiday as well - but this may be available in the grass/incoming
directory. What you *should* try to get is the User's Reference Manual;
if there is no kind soul around that can tell you how to get it, you can
always get the online man-pages with g.manual. And to get you started
with your (admittedly very simple) problem:
- start a monitor with d.mon [monitorname]
- set your geographic region to the map you want to have a look at with
g.region rast=[mapname]
- don't forget to run d.erase
- display your map with d.rast [mapname]
- zoom in with d.zoom (interactive!)
- run d.erase again
- display the map again
- saving to a new file of the zoomed area does not need the displaying,
but you might want to check; saving to a new file can be done in two
ways:
either r.resample [mapname] o=[new_map]
or r.mapcalc [new_map] = [mapname]
both will 'clip' your old map to your zoom region.
Hope this will get you going!
Philip Verhagen
