I'm not a GIS professional so I hope I use the correct wording, at least I hope you understand my question.
Let's say there are five polygons in the feature A. In the shapefile there are more features. In feature A two polygons from the five existing are intersecting. I want to merge the two so overlapping lines will be deleted and the result is one polygon.
A possible solution would work like this:
- I select the feature which 'activate' all five polygons
- I switch to edit mode
- I select the points of the two polygons
- I use function MERGE-SELECTED-POLYGONS
So far I found only functions to merge objects (features?), merge shapefiles, and so on.
Is there a function MERGE-SELECTED-POLYGONS?
