Dear list I am trying to run v.rast.stats for a large vector file. It contains around 700000 buildings representing buildings.
here is my g.region info g.region -p projection: 99 (Transverse Mercator) zone: 0 datum: osgb36 ellipsoid: airy north: 183010.45829976 south: 153516.19024768 west: 513122.49174945 east: 555953.95182415 nsres: 4.99987592 ewres: 5.00017045 rows: 5899 cols: 8566 cells: 50530834 THe problem I am having is the process is extremely slow. It has done 150 features out of 700000 areas after 2 hours. I need just the average raster value within each building (feature). My questions are: - Is there something I can do to speed up the process? - Is there a way just to get the average value rather than the whole set of statistical parameters (I am not even using -e option) Any advice on that is highly appreciated.
