What's next after installation?

First time users should explore the first steps tutorial after installation.

Individual users

When using GRASS GIS as a single user on your PC, then the /grassdata/ directory may be best stored in your HOME directory.

GRASS can be invoked with:

grass64 --help  # print options
grass64   # start with graphical user interface, presetting the defaults from last session (stored in /home/user/.grassrc6 file)
grass64 /home/user/grassdata/spearfish/david  # a specific mapset

Group users: shared network directory

Suggested directory structures:

 /data/            # as a shared directory for team projects with sysop managed group permissions
                   # this shared directory may stay on a network server
 /data/grassdata   # GRASS GIS database 
 /data/grassdata/spearfish60          # a shared spearfish Location (a Location corresponds to a project)
 /data/grassdata/spearfish60/maria    # a team member's mapset
 /data/grassdata/spearfish60/david    # another member's mapset

Important: do NOT enable group-write access on the location/mapset directories. Let GRASS GIS manage it properly.

GRASS can be invoked with:

grass64 --help  # print options
grass64   # start with defaults from .grassrc6
grass64 /data/grassdata/spearfish/david  # a specific mapset
