Figure C.2: GRASS database selection/creation dialog box
dialog box with values for our new database plumbed in (to create a
new database, just create a new folder using the browse button to the
right of the Database field).
Clicking the Next button brings us to the location screen. To create a
location, we simply provide a name, in this case alaska_data . Note that
the plugin will use not only the extent of the data loaded into QGIS but
also the projection information when creating the new location. Clicking
Next opens the projection page where we can customize the projection
if we choose to do so. If the layers loaded in to QGIS have associated
projection information, it will be preselected in the Projection list. In
this case, “NAD 27 / Alaska Albers (meters)” is selected. We don't have
to do anything further to define the coordinate system.
Moving to the next screen (by clicking the Next button) brings us to
Default GRASS Region. Here you can customize the region (think ex-
tents) for the location. By default, it will be set to the same extent as the
data loaded in QGIS. Usually you won't have to make any changes here.
