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:
