Hello Daniel, I also wanted to use r.area, so I installed it but had an error, as posted here http://osgeo-org.1803224.n2.nabble.com/New-modules-in-svn-add-on-r-area-and-r-convergence-td5161926.html#a5199839
Then afterwards Milton Ribeiro sent me another way to get the same results in a rather fast way. I don't want to interrupt your struggle to get r.area working, but if you need some fast results, I believe you could try this alternative: r.stats -na input=clumped_map | awk '{print $1,"=",int($2/10000)+1}' | r.reclass input=clumped_map output=clumped_map_AreaHA - --o The area is calculated in squared meters than converted to hectares by awk (but you can probably change units within r.stats) than sent to r.reclass. Hope this helps in anyway. Cheers, Marcello. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Installing-r-area-tp5340139p5360992.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
