Importing such a large file can take a lot of time because of the cleaning in order to get it into GRASS GIS' topological format.
Moritz, I assumed it would taka a while, but it seemed to be stuck. Perhaps because that polygon was large, complex, and needed a lot of cleaning.
I think it really depends on the specific file in terms of geometry complexity and cleanliness, so difficult to pre-determine. I regularly launch large import jobs overnight.
Then that's what I'll do tonight: I'll start it running in screen before I log off and let it do it's thing for as long as it wants.
You should see an information about its progress in the different cleaning steps (note that some cleaning is repeated).
I was using the GUI because I needed to create a new location and have forgotten how to create a new location and mapset from the command line.
If you are sure you do not want to do any polygon cleaning during import, you can use the -c flag. But you will have to handle the result with care.
Actually, I much prefer to let GRASS clean as it goes. Thanks very much for the knowledge. Stay well, Rich _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
