[GRASS-user] getting started

[Michael Barton]

Press the help button on the startup screen and read the startup help.

In brief, you need to select/create a "location", which is a working folder
for which you define the projection parameters. You can do this 3 ways: 1)
search the extensive ESPG list of projections for one that fits your working
area, 2) set the projection from a georeferenced file, or 3) set the
projection parameters manually. Once you have created a location, you can
simply select it and start to work.

In your case, you need a projection in NAD83, UTM, Zone 10N. I'm sure that
this is in the ESPG projections list.
