[GRASSLIST:705] Finding overlapping polygons with Grass

[Sudipta Sarkar]

Hi Guys,
I need to run several topological operations on a large number of polygon shapefiles. The first of the operation should be able to isolate overlaps and show the polygons contributing to the overlap so that one can check each one correct it accordingly. The second operation involves dissolving multi-part polygons.
Is there any way to these in grass? does anyone have any convenient script for doing one or both of them?
Any help will be deeply appreciated.
