[Qgis-user] how to find center of polygons and/or major and minor diameters

[Azzurra Lentini]

Hi to all, any suggestion on how to quickly draw the minor and major
diameters of different polygons? I have a shapefile of polygons: some of
the polygons are ellipses and others are similar to ellipses but not
regular.

My aim is to find the center of these polygons (In this aim I was thinking
to draw the 2 diameters and to use the intersection of these diameters as a
center point of the polygon)

Thanks, Azzurra
