moving raster maps across UTM zone boundaries

[Tim Szeliga]

Has anyone attempted to incorporate the GCTP
(Global Coordinate Transformation Package)
into GRASS?  Given lat/lon of center pixel,
resolution in meters and nl/ns of output,
it will create an ASCII file of line/sample/lat/lon
points.  My Global Imaging system can use this
to register an image to any other projection.
Possible projections include Albers, Lambert,
polar stereo, UTM, mercator, polyconic and
even the lat/lon projection favored by GRASS.
