Hi, unfortunately, there is no vector aggregation available at the attribute level. However you can transform your time series of vector point data into coarse raster data time series, aggregate it and sample the result with the point coordinates (t.vect.observe.strds). Make sure that vector points belong to single pixels, hence one point per pixel.

Is that possible somehow with t.vect.algebra? I blindly assumed there was something like t.rast.aggregate for vectors too, but there's no... I think maybe it is possible with t.vect.algebra given that the operation would be equivalent to v.overlay operator=or, but as with t.rast.algebra, those manual pages are just a mistery to my limited understanding... Can anyone give any hints? or hall I discard vector time series approach completely? > > Thanks a lot in advance! > > Best, > Vero > > _______________________________________________ > grass-dev mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/grass-dev
