A colleague in the northeast asked me to relay this question in hopes
of receiveing a quick answer from other GRASS users.He is trying to import data from an ARC-INFO system via a DLG file.
The DLG has point data in it represented as degenerate lines. He can
read the file and see the point data, and the v.in.dlg program recognizes
the lines and comes back with a message about degenerate lines. The file
also contains 1 line that represents a quadrangle boundary. After
importing the file to GRASS, he only gets the quadrangle boundary and no
point data even as degenerate lines. He know this because when he runs
v.support, it only shows 1 processed line. He is running version 4.0.What can he do to read in all of the data from the DLG?
If you still have access to the original data in ArcInfo, it's a heck of a lot
easier to bring it straight into GRASS, using the command v.in.arc, in the
UNGENERATE format. If you need specific directions, write me.
