I am working on QGIS latest version 2.12.3.
I am digitizing a polygon. It represents a riparian buffer of a river. The polygon made a continuous « loop » with a widht of 50 meters. I want to split my polygon into 8 sections that can be dealt with seperatly.
My problem is that i am unable to split to polygon. When i am using the « splitting » tool in advenced digitizing menu, the polygon does not split. It says « Invalid Geometry ». Therefore, the poylgon doesn't split. It suprise me because the same request use to work in others circumstances.
Do you have any clues on the matters ?
