I want to use the intersection tool in QGIS version 2.18 for two layers:
- Corine land use data downloaded from: http://land.copernicus.eu/pan-european/corine-land-cover/clc-2012 (a geodatabase, vector format)
- buffer layer in vector format.
When I try to use the intersection tool, I get an error:
"Input layer A contains invalid geometries (feature 1255). Unable to complete intersection algorithm."
Layer A is the Corine layer.
How can I get rid of this error and use the intersection tool properly?
