GeoPAT is a collection of GRASS GIS modules that integrates various tools necessary for processing geospatial data using information derived from spatial patterns in categorical grids.

This software is an extension of GRASS module r.clump. The difference between r.clump4p and the original r.clump is in utilization of "divide and conquer" technique and in taking advanatge of parallel computing using shared memory model (OpenMP) which results in significant performance gain. The module supports both, 4-connected and 8-connected cell connectivities.

This software is an implementation of machine vision-based "Geomorphons" methodology for fast and robust mapping of landforms from digital elevation models (DEMs). This implementation is made in GRASS 7 environment as a GRASS add-on module.
