[GRASS-user] patching dem at different resolution

Hi grass users, I have 4 dem, 2 are 1x1 m resolution and 2 are 2x2 m a resolution; I 'd like to have just one global dem 2x2 m resolution. If I import the data with their native resolution then I set the region to the total area with a resolution of 2x2 (g.region -a res=2 rast=dem1, dem2,

[GRASS-user] change resolution using g.region

Dear grass users, does anyone know which is the algorithm applied to a raster map when changing the resolution using g.region res=XXX? If I have a 1m resolution raster map and I change the region resolution to 2m using g.region, the new 2x2-cell values are an average of 4 cells in the

Re: [GRASS-user] How to convert BMP JPEG files to Shape(.shp) format

There used to be the way by using Autotrace. You vectorized the raster to the dxf format and imported it into grass by v.in.dxf. The rasters I was working with used the same projection as my location. I just had to make a v.transform on them and voila. Af far as it can be deduced from the

Hamish, GRASS 6.3 starts fine with -text or -oldtcltk options. The gui freezes with default or -tcltk or -gui options. What freezes is the GRASS 6.3.0 GIS Manager Map that is a complex map. I can't even close that window and have to logout to get rid of it. I did the compile myself. This is
