[GRASS-user] Determining maximum value of attributes where areas are overlapping in imported vector layer

[Rainer M Krug]

Hi

I am back with a problem of imported shape files:

I have imported a shape file and it contains several areas where
polygons are overlapping. After I managed to obtain the number of
overlapping polygons and exported it to a raster layer
(http://grass.osgeo.org/wiki/Vector_Overlapping_Areas), I would now
need the maximum value of an attribute column for this areas.

Any ideas how I can achieve this?

Thanks,

Rainer
