Dear all, I'm looking for a GRASS module that unify the geometries and the values, If I have a configuration like:
geo features | cat | id | A | B geofeature1 => cat1, id1, a1, b1 geofeature2 => cat2, id1, a2, b2 geofeature3 => cat3, id2, a3, b3 geofeature4 => cat4, id2, a4, b4 geofeature5 => cat5, id2, a5, b5 I would like to have something like: SELECT id, mean(A) as meanA, mean(B) as meanB FROM table GROUP BY id; geo features | cat | meanA | meanB geo1, geo2 => id1, mean(a1, a2), mean(b1, b2) geo3, geo4, geo5 => id2, mean(a3, a4, a5), mean(b3, b4, b5) There is already something to do this simple operation? Do you have any suggestions? Thank you Pietro _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
