[GRASS-user] how create new mapsets in grass bash scripts in parallel (equivalent of grass78 -c /path/location/PERMANENT -e)
I am trying to parallelize some scripts that currently run only one way .( Currently scripts just create a new temporary mapset and run some commands using --exec option of grass78) My understanding is that I should follow this, however I am unable to create a new mapset using this. https://grasswiki.osgeo.org/wiki/GRASS_and_Shell#Automated_batch_jobs:_Setting_the_GRASS_environmental_variables Here is what I have tried and failed 1) grass78 executable cannot be run parallely from bash even to just create the mapset 2) g.mapset -c 3) g.proj -c If there is a different way to create a new mapset, please let me know (I am not sure if its as simple as copying some files from a template location...) #current grass scripts #Step 1: Create a new location with permanent mapset grass78 -c /path/location/PERMANENT -e #Step2: run some commands using--exec option grass78--exec v.in.ogr input='$inputfile' output=$vecoutname location=path/location/PERMANENT ___ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
Re: [GRASS-user] Raster null values unchanged by r.null
Hi Ken, This is on a native Grass raster, not through a file linked by r.external. It seems to be some problem with the rendering/refreshing in the WXGUI. ~ Eric.

Re: [GRASS-user] Help needed with a coordinate projection problem
Hi Thomas, I have no suggestion other than to create an issue here https://github.com/OSGeo/grass/issues with a reproducible example so others can easily test. Also report the GDAL and PROJ versions you have.
