Vector Processing Plugin
The Vector Processing plugin contains
several
processing algorithms applied to vector data. Such as Aggregation, Buffer and Intersection.
- Aggregation
- The Aggregation operation is applied to
a
single layer and
a chosen group of attributes that can be summarized. The idea is
to generate a new layer with summarized information. The geometries of
each group are aggregated through the UNION
spatial operation and the attributes can be summarized using of the
aggregation operation: sum, count, maximum, minimum, average and so on.
- Buffer -
The Buffer is a spatial
operation that can be
applied to a single layer. The buffer zone may be defined as an area
generated around an object with a predetermined distance.
- Intersection
- The Intersection is spatial
operation and can be applied for two layers. One containing polygons
that form a clipping mask, and another (with any kind of representation
ex. polygons, lines, points) will be clipped. The result is a new plan
formed by the objects of the second theme in the intersection with the
clipping mask.
