[GRASSLIST:8873] Re: GRASS 6 in a nutshell tutorial

[Ian MacMillan]

Luigi, I am not sure about your manual problems, but you can grab data  
of California from several location for free.  Try  
http://data.geocomm.com/ for a vector outline of the state.  You have  
to create an account on that site, but it is free, and they have a lot  
of useful data.

The best DEM of the state can be had from the USGS seamless server  
here: http://seamless.usgs.gov.  DEMs of a variety of resolutions are  
available there.

If you have already imported data and can't view it, have you made sure  
to set your region?
g.region rast=your_rast
or
g.region vect=your_vect
then
d.rast rast=your_rast

Hope this helps,
Ian

What happens if a big asteroid hits Earth? Judging from realistic  
simulations involving a sledge hammer and a common laboratory frog, we  
can assume it will be pretty bad.
