<font face="Times New Roman, Times, serif">Hi all,<br>
<br>
Is it possible to do a first order GCP-warp *without* shearing? I
have a rectangular scan with very imprecise control points, and I
want it georeferenced without any distortion. With a first order
gdalwarp I get back a map in the form of a parallellogram. Is
there a way to get back the original rectangular form? </font><font

off, of course, but I am interested in the original forms of the
mapped items.</font><br>
