Moritz Lennert wrote: Looking into the potential of using GRASS for multi-criteria analysis, I came upon Peter Löwe's article about r.infer in GRASS News Vol. 3 [1]. He also mentions r.weight and r.combine in the article (all from 5.4, never ported to 6.x). I'm not sure I completely understand what these three can do what r.mapcalc cannot do. Is it only a question of ease of usage ? (no idea) If they do prove to be of added value, are there any people out there who would be interested in reviving these modules ? The raster format did not change between GRASS 5 and 6, so as long as those modules do not access sites or vector maps porting to GRASS 6 usually just means copying it into the source tree and creating a new Makefile for it (copy adapt that from a nearby GRASS 6 raster module) fwiw: http://grass.osgeo.org/gdp/html_grass5/html/r.weight.html -- assign weights to category numbers, and overlay multiple maps. The resulting output raster map layer depicts the combination of map layer weights across a landscape. These values represent a hierarchy of suitability for some user-defined purpose. http://grass.osgeo.org/gdp/html_grass5/html/r.weight2.html -- r.weight2 is the non-interactive version of r.weight http://grass.osgeo.org/gdp/html_grass5/html/r.weighted.cn.html -- The r.weighted.cn program is sensitive to the current window settings. Thus the program can be used to generate a weighted CN map of any sub-area within the full map layer. http://grass.osgeo.org/gdp/html_grass5/html/r.combine.html -- r.combine accepts commands that are similar to those used for boolean combinations (AND, OR, NOT) in order to overlay user-selected groups of categories from different raster map layers. I think a similar method (assigning weights to category numbers) can be done with r.category, although that functionality is hardly ever used now that we have real FP raster maps.

Re: [GRASS-user] v.in.ascii - put1 of 4 columns to 3D point file attribute
Mark wrote: The points are about 5 million per tile, and there are 23 tiles (about 115 million total). I'm not sure if this is considered a large amount of mass input points. Yes, it's a lot. The current vector engine allocates a small amount of memory per feature for topology. With the DBF as database and default v.in.ascii settings I've only ever managed to import about 3 million points before running out of memory. I am interested to hear that you could load 5 million into a SQLite DB, maybe that is more efficient. With the v.in.ascii -t and -b flags you should be able to load 25million+ points into a single vector map, but there is a limited number of modules that will be able to use a vector map without topology. (importantly v.surf.rst still works) If you are willing to abandon your code data column, you can strip off that column and import the rest as a 3D vector (-z z=), in which case no table is created (or just ignore it with -t -z). If you are just interested in the 3D coordinate, then a DB table is unneeded overhead and is best skipped. Question: what do you want to do with the data? Simply create a raster DEM or do more fancy cleaning with v.lidar.*? If just creating a raster DEM you might skip v.in.ascii altogether and use the r.in.xyz module.
