Quite a straightforward question:
I have a point layer that consists of a few thousand points. These points are heterogeneously positioned in or very close to polygons that are water bodies. These polygons differ in size. I would like to cut the polygon based on the location of these points.
Please look at the example below. Blue polygon (water body) and black point is what I have right now. The purple, red or green lined polygon (or line) is a example of what the result can look like in order to clip the blue polygon. Which approach do you suggest?
Perhaps that a buffer around a point would help. The tricky part is that the buffer should match the two closest edges of the surrounding polygon. Or maybe to create a line to both sides?
