Creating a new GRASS vector layer
<A NAME="490"></A>
To create a new GRASS vector layer with the GRASS plugin click the
grass_new_vector_layerCreate new GRASS vector toolbar icon.
Enter a name in the text box and you can start digitizing point, line or
polygone geometries, following the procedure described in Section 9.7.
In GRASS it is possible to organize all sort of geometry types (point, line
and area) in one layer, because GRASS uses a topological vector model, so you
don't need to select the geometry type when creating a new GRASS vector. This
is different from Shapefile creation with QGIS, because Shapefiles use the
Simple Feature vector model (see Section #sec:create_shape).
