Figure C.10: Setting up to digitize a new map in GRASS
Figure C.11: GRASS digitizing tools
helpful from a learning standpoint so you can see what commands are
used to accomplish a task in GRASS.
Once we click the Run button, two things happen. First, a Monitor win-
dow is opened, and the layer(s) we specified as background are drawn.
Second, the v.digit tool window appears, as shown in Figure C.11 . Together
these two windows provide us with the capability to digitize features.
The first step is to zoom into the area where we want to work. Let's
start with Lake Tanganyika, located in the Great Rift Valley near 29.57
degrees N latitude, 6.16 degrees W longitude (the v.digit tools dialog box
show latitude/longitude at the bottom left of the window).
