Lines in the vector file

[Christine Weiss]

Hi,

This problem can be approached a couple of ways: v.extract - which theoretically should "extract" whatever labelled lines you need, leaving the unlabelled lines behind (thus bulk removing unlabelled lines).  However, I haven't had too much luck with that program.  v.reclass should work nicely though.  Simply reclass the map, (reclassing the values to the same values, ie.- line #1 you should still reclass as #1) and the new reclassed map will only have the lines that you reclassed.
