Zonal histogram processing and invalid geometries
Geographic Information Systems Asked by Beto Jacintho on June 5, 2021
In QGIS 3.4, when I try to get a zonal histogram it returns an error related to invalid geometries in the vetor layer.
I’ve fixed geometries and, despite the layer have seemingly only valid geometries (as showed in the check geometry results), the "zonal histogram" algorithm keeps in the "calculating field" stage, without progress.
One Answer
To solve this, try this, just go to the process toolbox, then vector geometry and run Fix geometries on the input layer
This will generate a new layer, corrected, with which you will work
