Hello Sören, Thanks for your answer :)

Yes, after I wrote to the list, I thought of this by-pass, too (v.to.rast, create the strds and register maps, to then aggregate as desired and sample with t.vect.observe.strds). However, I'll loose the attributes in the original vector points. So, I thought of better splitting the original vector by weeks in R (split), then write all weekly vector maps into grass (writeVECT) and register the STVDS. btw, is that paper regarding temporal algebra you mentioned once already published?? I would like to study that. Thanks again :) Best regards, Vero _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
