I have been processing DLG's with v.in.dlg's matt option. Has anyone written or been using a script that will allow the user to select the desired attribute from the matt output and create a dig_cat file? If so please respond. THANKS!!! $:^) Sharon Shin National Biological Survey sharon at its.nbs.gov 303-969-2599 (voice) 303-969-2822 (fax)
