[GRASS-user] getting started

GRASS GRASS user

I'm a GRASS newbie. I want to generate some maps on top of usgs color
orthoimagery (as nad83 utm zone 10n geotiffs), using wgs84 decimal
lat/long point data. When I start up GRASS I am immediately faced
with questions I don't know the answers to, the whole
mapset/location/bounding box/datum/something-about-raster-pitch/etc.

Can someone help me get started?

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.
