I'm trying to intersect two vector layers (having the same CRS EPSG:4326 WGS 84, in QGIS 2.18.10) but I get this error in the log:
Input layer A contains invalid geometries (feature 52). Unable to complete intersection algorithm.
I have checked the validity of both layers and in both cases there are no errors or invalid geometries. Nevertheless, I have deleted feature 52 of the layer with the invalid geometry, and when I intersect them again, I find an error on feature 51, and so on until I delete every single feature.
- Is there a way to check for errors in the geometry other than 'check validity'?
- Could it be another type of error that QGIS is trying to indicate?
