r.agent
r.agent (src) shall provide an inital base for organizing worlds with raster playgrounds and agents in. Still under development.
- Author: Michael Lustenberger
r.area
r.area (src) can be used to remove, areas smaller than treshold, reclass according areas (similar to r.reclass area, but work in cells, not hectares and allow create more classes)
- Author: Jarek Jasiewicz
r.clump2
r.clump2 (src) finds all areas of contiguous cell category values in the input raster map layer name.
r.convergence
....
r.convert
....
r.damflood
The definition of flooding areas is of considerable importance for both the risk analysis and the emergency management. This command is an embedded GRASS GIS hydrodynamic 2D model that allows to obtain flooding area due to a failure of a dam, given the geometry of the reservoir and of the downstream area, the initial conditions and the dam breach geometry.
- Authors: Roberto Marzocchi and Massimiliano Cannata
r.flip
Flip raster map
r.forestfrag
- Shell script that creates forest fragmentation index from a GRASS raster map (where forest=1, non-forest=0) based on a method developed by Riitters et. al (2000).
- Author: Maning Sambale, Stefan Sylla and Paulo van Breugel
r.fuzzy

r.gdd
r.gdd (src) calculates (accumulated) growing degree days (GDDs) and Winkler indices from several input maps with temperature data for different times of the day.
