Below I describe the method I am using.
I have two machines:
- ubuntu linux, qgis 1.4 - intersection works
- WIN xp, qgis 1.8 - intersection does not work
Hopefully, someone will find what I am doing wrong I uploaded this screencast showing my problem. The error massage:
"Feature geometry error: One or more output features ignored due to invalid geometry. Some output geometries may be missing or invalid."
I also tried some other tweaks:
- buffering the points layer so I will be doing polygon/polygon intersect - didn't work
- saving both layers while specifying the same CRS - didn't work
What am I missing here?
