Hello,

I need to transform some data in ascii vector format and
state plane coordinates into UTM coordinates.  I noticed
that v.transform can do this if you provide it with a
file containing 4-10 transformation points.  Can anyone
suggest a way to determine these transformation points?
Also, the man pages for v.transform says that it does not
work very well with states using the Lambert Conformal
Conic Projection.  Does it work well at all and how do I
determine how well it is working?

Thank you,

Brian
