[GRASS-user] How to combine rasters?
I have 3 rasters: 1. Lakes with value 2.5 2. Rivers with value 1 3. Mountains above 1000m with value 3 I need to combine the 3 rasters so as Lakes' values dominate on Rivers' and Mountains' values and Rivers' values dominates on Mountains' values. How can I achieve that? Is r.patch suitable for that? Where can I find any tutorial with raster combination like that?

[GRASS-user] obtaining spatial data from shapefile maps
I want to use GRASS (and QGIS) for analysis of water well locations in a town. The basic data has been provided thru (ARCWare) shapefiles. While input of data to create the well location point maps is no problem, the shapefile format embeds the "real" spatial location data in a proprietary file (the .shx index files). So I can input shapefile data, including the dBase attributes, I can't get at the spatial locations; consequently I can't correct for any location errors made as a result of data input mistakes. Is there a way to access these shapefile index files using GRASS? Or is there a way I can use that fact that I can produce a GRASS location map of points to obtain (say a table of) (x,y) relative to some know location on the map? If I could solve this problem, I could probably move the whole well data set out of shapefiles and into more accessible database system, e.g. MySql. thanks, --dick peskin Richard L.

I had been trying to use v.overlay to clip a line vector map (of roads), but it added an "a_" prefix to each of the field names in the attribute table. I also seemed to have to add a centroid to the vector created by g.in.region to get v.overlay to work. Finally, v.overlay resulted in 5,451 lines compared to 5,444 from v.select. The extra lines were copies of 4 lines that all happen to intersect the binput map boundary. -Dwight ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
