My aim is to calculate catchments for around 150 points and to extract land-use variables for them. In order to do so I need a vector dataset where no polygons overlap. This, however, seems to be a challenging task.
Presume, that I already calculated the catchments for all 150 points (see Figure 1; here only points 1-6 are visualized):
How do I get from the overlapping catchment features in Figure 1 to the none overlapping catchment features in Figure 2?
How can I associate the catchment features to previous overlaps? I thought of adding up the IDs (see 'Sum ID Overlap' in the attribute table in Figure 2). Can this be done automatically?
