[GRASS-user] Merge polygone with same attribut of a shapefile

[BLANDENIER Lucien]

Dear all,

I'm trying to merge all polygones with the same attribut of a shapefile. I saw it is possible to merge adjacent polygone with r.dissolve but I didn't found how to do this with polygones that are not adjacent. Is there a way to do this?

My goal is to minimise the number of feature into my table in order to have only one feature by category, but containing several polygones.

Regards

Lucien
