Hi, I just added a new script to the wiki addons page, v.random.cover. http://grass.gdf-hannover.de/wiki/GRASS_AddOns#Vector_add-ons
It's like v.random but points are constrained to within specified areas in the cover vector map. example: # create 40 random points to fall into areas with cat ids of 18,22,47. # Spearfish dataset v.random.cover cover=fields cat=18,47,22 out=field_rand_40pts n=40 Perhaps useful to r.le and r.li users for setting up sampling sites. It could probably be better written into the v.random module using the the point-in-polygon test used in v.buffer before writing the point and i++. Only after I put it up on the wiki did I notice r.random already had both cover map and vector_output options. Oh well, more ways to try. enjoy, Hamish ps- The add-ons page has grown very large and it is hard to find stuff. We should figure a way to break it down into smaller sections. If anyone has ideas can you comment in the discussion section of that wiki page? _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
