Hi all,
I have been using v.extract to select out points using the 'where' option. I
run 6.3cvs,
and updated from the CVS repository yesterday (10 July). Suddenly v.extract
was unable to extract out any points. I noticed that there were changes in CVS
to v.extract on 4 July (the log entry says "BugFix: Do not extract centroids
outside area"), and I'm wondering if these changes introduced another bug.
My workaround was to do the v.extract using 6.2.2RC1, but wanted to call
this issue to somebody's attention. Below are outputs from v.info and v.extract
for my problematic case.
Best regards,
Allan Hollander
