	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, [http://grass.osgeo.org/grass64/manuals/v.overlay.html <code>v.overlay</code>] ~~For~~ the ~~purposes of these~~ examples, ~~the~~ two datasets ~~that we will use are~~ <code>urbanarea</code> and <code>census_wake2000</code>~~.

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, [http://grass.osgeo.org/grass64/manuals/v.overlay.html <code>v.overlay</code>], which can either be run using the GUI or from the command-line interface. The following examples are demonstrated using the CLI, using two vector datasets, namely: <code>urbanarea</code> and <code>census_wake2000</code> from the North Carolina database.
