How do I remove edge lines?

[Rick Thompson]

Hi James,
  If the category #s are the same on each side of these internal lines, then
using v.reclass with the -d option will dissolve lines where the same category
# is on each side (you can construct a reclass file from your dig_cats file). 
  If the category #s are not the same, but the label is the same (and the label
 
is a single descriptor like AB505), you can use the v.merge GRASS command that 
will standardize category #s. The last information I had on the v.merge command
 
was that it would not deal with text strings as labels in the dig_cat files 
(text separated by spaces). I worked around this by making a v.merge script tha
t
would deal with text strings, plus dissolve common lines. If you would like thi
s
script, I can make it available. Rick
