I keep having problems trying to intersect two shapefiles.
One of them is a normal file that I downloaded from geoamenagement.com. The other I created by using the classification protocol tool on an image of a region ENVI 5.3, and then I saved the map as a shapefile. Whenever I try to intersect the two files, I get this error
Feature (155131) of “Forest” has invalid geometry. Please repair the geometry or change the processing setting in the "Ignore invalid input features" option.
or sometimes I get an empty file.
NB: I'm using QGIS 3.28.2
