Hi all, I have a vector, with three layers each connected to a different table.
I heard about v.db.join and thought that would be a great tool, which it is but it doesn't satisfy me for this purpose, as it seems to result in the joined info displaying like one big table with all data from joined tables together. I would prefer to keep the info from each table on separate layers just so I can do things a particular way. Currently when I digitise an area, I add the cat for each layer. Is there a better way to do it, a bit like an update query? Because I could digitise the areas and do the cats for the first layer, then the other layers share a common value in a 'date' field which could join them. or a partly-automated, partly-manual approach where I tell GRASS to add to vector layer 2, a cat value of x, when the date (of layer one) =y I have spent some time going through GRASS manual for various things, but so far haven't had anything hit me in the face as being an answer to this... maybe I need glasses... ;-) _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
