[GRASSLIST:4944] Re: adding mile markers to curvy roads

[Dan Jacobson]

Radim> v.distance (to get starting point) + v.segment + some script.
Radim> Maybe also v.build.polylines.

Comparing v.distance.html's DESCRIPTION:
5.0.3:
v.distance uses a binary vector file (map=name) and user specified
coordinates to calculate the distance from the given point(s) to the
nearest line or point in vector layer.

5.7:
v.distance finds features from one vector (from=) feature to another
vector (to=) nearest feature. Various information about relation
(distance, ...) may be uploaded to attribute table attached to first
vector map or printed to 'stdout'. A new vector map may be created
where lines connecting nearest points on features are written.

Sounds complicated. Same with v.segment. Deep. Dark. Wait,
Hamish> you should check out Radim's LRS modules:

Hey, that's just what I need.  But all there are are PDF's, no modules
to be found.
