[Qgis-user] finding the radius of a curve

[Cory Albrecht]

Hello all,

I'm looking for a way to find the radius of a curve (for roads, railyways)
in QGIS. If it were a paper map I could do it with a drafting compass
(calipers to some) and a ruler, but this is a PostGIS layer.

Any plugin recommendations or links to a set of steps to accomplish this?
Thanks in advance!
