[GRASS-dev] [GRASS GIS] #1798: all relevant vector modules should have cats and where parameters

[Newcomb, Doug]

I guess the question is, if you then performed v.rast.stats for an
underlying raster using the overlapping buffers generated with -t , how
would the statistics for the overlapped polygons work?  Think 2 1km circles
whose centers are .75km apart.
