[GRASS-user] calculate pixel areas with starspan

[maning sambale]

Hi,

I have grass rasters and I want to calculate raster classes based on
the attributes of a shapefile.  I'm experimenting with starspan and so
far its extremely fast than:

v.in.ogr #to export shapefile
v.build and v.digit #to check for topology problems
v.to.rast
r.report

But, how can I get area coverage (in percent and hectares) from a
given raster class in a polygon?

Any ideas?

Cheers,

Maning
