Does anyone know where I can obtain LT+ for
DOS, AIX, and HPUX?
Well, I don't know about special versions for these systems,
but the code is in the GRASS4.1 distribution.
I've also put it into a single tar file which is available as
/pub/packages/grass/LTPlus.tar.gz on
ftp.informatik.uni-kiel.de

I need to rectify a map (1966 forest service publication that seems
to be a mercator projection, 7"x10") to lat-long.
i.rectify does a poor job. Is LT+ what I want to use?
I have scanned a map of the western US (lambert projection)
and want to register it as lat-long.
i.rectify does a poor job. It looks OK at the edges or in the middle
points but not both. The error is as much as 200 miles. The number of
points I use does not affect error very much. Is the problem
because i.rectify expects a more planar image (such
as a satellite image)? Do I need a way to convert the lambert
(conical) projection into a cylindrical one? Grass 4.0 does not seem to
have a module to convert coordinate systems in this way. How do we
get a more accurate registration/rectification?
This must be a problem solved every day somewhere, but we are stumped for
now.
