I am trying to import a vector layer into GRASS, but I keep receiving the same error. The values in the vector layer are important because I would like to use them to create a heatmap. What could I be doing wrong?

Yesterday I managed to import the layer into GRASS, but it had discarded all the values.

The error message received when trying to import a vector layer into GRASS

  • Perhaps there is some error with QGIS? I know that there are some features that I have problems with in GRASS since installing certain plugins. Uninstalling and reinstalling QGIS did not help, but I did manage to repair some of the damage by manually replacing missing files. Is there another way to 'repair' QGIS?

  • Tried this method, it just results in an error as well.

  • Have you checked the layer's geometry validity? I had the same trouble recently and that did the trick for me.

  • Sorry, still rather new to all of this. How do I check the layer's geometry validity?

After many fruitless attempts, I finally changed the columns around in the spreadsheet and voila! It worked. Thanks for all the help offered.
