DESCRIPTION

r.pi.rectangle converts sampling points (e.g. GPS coordinates) of the corner of a sampling site into an area by generating a defined rectangle. Generates a rectangle based on a corner coordinate.

This modules aims at generating sampling areas which are only known by the coordinate of one corner. The input are single points, while the output are areas representing the corresponding area for each of the single points/coordinates.

NOTES

The areas can only be generated horizontally, not diagonal. This can be added as wish and might be implemented in the future.

EXAMPLE

An example for the North Carolina sample dataset:
g.region -d
...
