I am trying to remove duplicate line segments from a table for segments
with matching start and end coordinates. However, I need to include a
tolerance of about 2m since they are not exact matches. Also the start
and end coordinates of matching segmets may be reversed!? Is there a
canned way to do this with postGIS?
Thanks for any help.
