[GRASS-user] Vector layer: percentage of shared perimeter

[Eduardo Corbelle]

Hello list:

I have an intuitive idea about an operation with vector polygons but I
don't know how to accomplish (if even can be done). I will appreciate
your comments and suggestions:

I have a vector layer consisting polygons of several classes. What I
would like to calculate for each polygon (without regard of the class it
belongs to) is the % of its perimeter that shares with adjacent polygons
of a given class.

Best regards and thank you very much.
