I'm using QGIS 2.6.
I'm trying to clip the polygons in one layer by another but cannot get the results I expect. I have a layer with wetland areas, and another layer with the boundary of my client's property. I want a layer showing only those wetland areas that lie within my client's property. If I run the 'Clip' tool, the resulting layer has nothing on it. It makes no difference which layer I use as the input layer and which as the clip layer, the result is always no features.
Could anyone explain what's going on and what tool might do this operation if not 'Clip'?
