I’m tediously moving one line out of
the way, deleting the second line and the point, then moving the first line
back again. I don’t know that I could specify only certain points to be
removed programmatically.
Rich, it’s an editing hell…
Maybe try to use <v.select> to select points that lie on boundaries and then remove them?

Both are rather
painful to endure, but I'll be finished with the editing well before the
elections.

That may not work because there are still extraneous points not on a
boundary.
Part of the problem, I think, is that whoever digitized these maps was
thinking ESRI: the results are used for digital cartography, not spatial
analyses. Ergo, section and township lines are frequently multiple segments
rather than a single line, and I'll bet the digitizing direction is not
constant.
Fortunately, I need these only to approximately locate sampling locations
based on the hydrology map and paper maps from the client. As long as I get
the locations on a stream the exact coordinates are not important for this
project.
Thanks, Alexander,
Rich
