[GRASS-user] Change GRASS region multiple times

Hello! I'm working with pygrass, developing a new module for GRASS. I need to create a new raster map during the execution. I'm using the commands: from grass.pygrass import raster newRasterMap = raster.RasterSegment('new') newRasterMap.open('w', 'CELL') I've noticed

Re: [GRASS-user] stream network

Hi Will, When running r.watershed on a small 35 hectare watershed, it produces a fully connected stream network. However, when running r.watershed on a 6400 hectare watershed, the stream network is not fully connected. No preprocessing with regards to merging different raster maps, however, I did

Re: [GRASS-user] stream network

Hi Janet, Can you give some more information about what you mean by larger watershed basins? Did you do any preprocessing of the elevation raster before you tried to extract the stream networks? Were you using an elevation raster that had been merged from different rasters? I've ran into

[GRASS-user] Parallel proccess with pygrass and mapcalc

Hi I'm writing a code in python able to perform several mapcalc operation on various rasters. I'm using GRASS 7.0.1 and Python 2.7. I'have my files stored in /home/myuser/rasters/ and they are linked to GRASS with r.external. The out put of the operation are going out of GRASS in /home/myuser/tmp/

[GRASS-user] stream network

Hi GRASS community, When creating a stream network with r.watershed, I end up with some isolated stream segments - particularly in larger watershed basins. Does anyone know how to generate a stream network that is fully connected, or how to correct this issue? thank you, Janet

[GRASS-user] Help with steps to output DEM, raster overlays and vector overlays to VTK based on NVIZ settings

Hi, Wondering if someone can point me in the right direction. I have grass 7. I am using NVIZ to display a dem with raster and vector overlays. Looks fantastic. I now would like to export this model (with colours and light settings etc) to VTK, ultimately so I can convert it to dae
