I digitized already two areas, bordering each other on one side. Than I realized, more detail was needed! What do you suggest as a fast way to do so?
- Adding each time new dots/verteces takes so much time.
- But, adding a new polygon and merge both (as I used to do for a not bordering polygon) does not seem that easy in this case.
- Using the split feature causes an invalid area which I cannot merge with the other area afterwards.
