Prevent polygon feature (catchment) overlap

LaraFaelivrin — Sat, 22 Aug 2015 07:55:52 GMT

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?

It may be easier to just do run each adjoint catchment one at a time through zonal statistics.
