Vector Spatial Analysis

The following examples demonstrate how basic vector data processing operations, such as overlay, union and clipping can be performed in GRASS 6.4. These operations are all performed using the GRASS module, v.overaly For the purposes of these examples, the two datasets that we will use are urbanarea and census_wake2000. All examples are created using the vector datasets in the North Carolina database.

d.mon start=x0
d.vect urbanarea col=blue
d.vect census_wake2000 col=red type=boundary
