[GRASS-user] remove sliver polygons and dissolving adjacent ones

Dear all,

First, I would like all polygons with area less than, for example, 100 squaremeters, to be joined to adjacent ones with a larger area. There is a module linked to the polygons sliver, right? Finally, the thing to which I just can not give a solution. I would like to “merge/dissolve” just the adjacent polygons that have the same attribute. How can I do?
Thanks

Hei Giuseppe,

For your first task use v.clean: https://grass.osgeo.org/grass76/manuals/v.clean.html

For the second v.dissolve: https://grass.osgeo.org/grass76/manuals/v.dissolve.html

Cheers

Stefan
