GRASS databases as you desire. For this example, we'll use a directory
in our home directory named grassdata . The QGIS/GRASS plugin can
create this directory as part of defining our new location and mapset.
Creating the Location
Let's start by running QGIS and loading the data that covers the area of
interest. We'll use the standard Alaska sample data here and load just
the coastline and the Russia/Canada boundaries. If you don't already
have the sample data, you can get it from http://desktopgisbook.com . In
Figure C.1 , you can see QGIS with the data loaded and ready for us to
use the GRASS plugin.
Now it's time to create the database, location, and mapset. Choose
GRASS from the Plugins menu and choose New Mapset. Here you can
choose an existing database directory or create a new one. The dia-
log box provides some visual cues as to how you should proceed. In
Figure C.2 , on the following page, you can see the database selection
