stampr provides tools for performing spatial temporal analysis of moving polygons.
These tools allow the calculation of directional relationships, shape indices, and other basic
functionality, such as global change metrics. More details about each of these functions
can be found in its help documentation.
stampr's functions utilize the
SpatialPolygonsDataFrame objects from the
sp. Polygon relationships are still understudied in the field of
geographic information science, but hopefully
stampr can provide users with a
platform for new developments and applied research looking at interesting geographical phenomena.
