Tool Polygon Dissolve

Merges polygons, which share the same attribute value, and (optionally) dissolves borders between adjacent polygon parts. If no attribute or combination of attributes is chosen, all polygons will be merged. Uses the free and open source software library Clipper created by Angus Johnson.
