Re: SV: Re: [GRASS-user] Weighted Voronoi diagram
Dear all, sorry for picking this up so late, I just got around to reading through the latest 1100 list posts for the first time in weeks! I have recently updated r.xtent and made it a lot more robust, fixing all known issues: http://www.quantarch.org/files/r.xtent.tar.gz You will have to compile it yourself as explained on the GRASS add-ons page: http://grass.osgeo.org/wiki/GRASS_AddOns No binaries yet and no time to create any, sorry. The new version also includes normalization of the weight attribute [0..1] which is very important for stable model behavior. I have removed all options for automatic generation of cost surfaces, as those were clunky calls to the r.walk and r.cost modules which did nothing except complicate the r.xtent user interface. You now have to generate your own cost surfaces (if needed) for each site and put the name of the cost surface map for the site into the site map attribute table. Pathways and boundaries are working again. Note, however that when you add line features to raster cost maps, there will be diagonal gaps between the cells that make up the line if it bends in any direction. To close those, use: http://www.quantarch.org/files/r.burn.frict.sh Otherwise, the cost surface algorithm will slip through the gaps ... Note that the HTML manual page is now out-of-date the only current information is in the r.xtent program options. I would like to commit r.xtent to the GRASS Add-ons repository some time, but it cannot go there until the HTML manual page has been revised. I don't have any time to do that right now, so if anyone feels like helping with that, I'd be very grateful.
