[GRASS-user] 3D raster color coding

Hi, I have created a 3D raster from soil properties with about 70K points, with a* lot of help from the mailing list i must say*. from the copy of the metadata of the 3d raster (below) it would confirm that the 3D raster worked and the grid is populated with data. I have copied below the r3.colors

Re: [GRASS-user] v.color takes a long time for 2E6 records

Hi Everyone, When using v.color on a map with 2 Million points, it takes more than 24 hours (I guess the last time it took near 40 hours). The CPU is busy less than 20% on a 8 core machine and a lot of memory is available (50% at least is empty out of the 16 GB). Is there a way that I could accele

Hi Micha, Thank you -- I looked at this previously, but I think I misunderstood what it did. I've tried r.stream.slope and it sure looks like it's doing what I need. Thank you for encouraging me to re-visit it! Best, Tom On Wed, May 30, 2018 at 3:34 PM, Micha Silver wrote: > Hi Tom: > > On 05/

Hi all, I have written an involved script (which I run automatically), in part, calling r.basin to get the stream channel slope (preferably at the basin outlet). For all basin outlet locations, r.basin defines the watershed correctly, but for about 10% of the locations the *_parameters.csv file is

Dears, I guess there is no GRASS GIS built-in implementation of GDAL's VRT concept (several related ideas listed https://trac.osgeo.org/grass/wiki/Grass8Planning). Once past some compilation issues, I am about to try to build a VRT based on native GRASS GIS raster maps (using GDAL with support f
