Hi Andr, You mention that you have streams of different 'order', does that mean you have a table connected with a column containing a value for each bit of stream (e.g. the river and tributaries are a combination of vector lines, and each line between one stream junction and the next has a 'stream order' number)?
If so, could you do something as simple as putting a sql query in the 'where' box of the properties dialog (on the 'selection' tab)? e.g. (where) stream_order_column<4 ? This has worked for me when viewing a stream-order vector map with appropriate values. (this properties tab is the gui for d.vect, if you're looking for it by other means) I am not sure if, after that stage, you may be able to save a copy of that vector with the same 'where' criteria applied during the copy process, to then have a smaller vector file for your own use. Or copy the entire vector then delete/drop the vectors (and attributes from table) for the higher-order streams you don't want? Any other thoughts on this one people? or am I paddling up the wrong stream, so to speak? -shane. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
