[GRASS-user] Help to compute polygon extent

[Sophie Leguedois]

Dear all,

I would to compute the maximum extent length for multipart polygons (ie the
distance between the  2 remotest vertices of the boundary limit; see the
attached picture). Is there a designated tool to do that or do I have to
compute it?

Thank in advance for your answers.
