I have to transform into digital format a lot of scanned maps. Not everything on them but only some major zones that have the same colors.
I was wondering if Is there any tool capable of transforming some regions with the same color into a polygon. I've been looking around all day buy came up empty handed.
Think on a country with all it's states in different colos. I have to separate each state as a lone polygon.
