[GRASS-user] New modules in add-ons: v.in.geoplot, r.xtent + r.burn.frict

[Benjamin Ducke]

I have added some new modules to the Add-ons repository:

http://grass.osgeo.org/wiki/GRASS_AddOns#v.in.geoplot

http://grass.osgeo.org/wiki/GRASS_AddOns#r.burn.frict

http://grass.osgeo.org/wiki/GRASS_AddOns#r.xtent

Descriptions:

v.in.geoplot converts a Geoplot 3 ASCII export file to a GRASS vector map layer.

r.burn.frict converts vector geometries to raster cells, using a simple anti-aliasing method to close "gaps" between diagonal cells. Useful for "burning" vector geometries into a friction surface, making sure that simulated movement does not "slip" through converted cells that have only diagonal neighbours.

r.xtent computes a raster map layer representing the Voronoi diagram, weighted Voronoi diagram or a more complex territorial partitioning of space around points (centers) in a vector input map, based on the XTENT formula.

r.burn.frict and r.xtent are really intended to go together for creating realistic territorial models.
