Hello all,<br>I've created a vector thematic map with a dozen of different areas (different units in a viticultural zoning study).<br>For the same region, I've got a few rasters as well: DEM, slope and aspect, annual precipitations, solar radiation, Winkler's index, ....
<br><br>What I need is an estimate of some statistics as min, max, mean values of each variable (elevation, ...) for each particular region. What do you suggest as the best method (for what concern speed and, above all, quality of results) in order to accomplish this task?
<br>I only can imagine this:<br><br>1) transform the vector map in raster<br>2) use r.statistics (as in the example in the manual) or maybe r.statistics applied to the rasters of climatic variables after masking for each particular area.
<br><br>Is there some better way, in particular a way which doesn't involve transforming the vector map to raster?<br><br>Thanks in advance.<br><br>Odoardo Zecca<br><br>Institut Agricole Régional<br>Regione La Rochère 1/A
