<font face="Times New Roman, Times, serif">Ah, Mirone is a Matlab
based graphical interface to Gdal, that uses Matlab routines for
warping in addition to Gdal. What I am looking for is a
command-line tool to warp an image without any shearing. Ideally
in the form of an option to Gdal. Is this possible, or can it be
made? It wouldn't be too difficult to adapt the -order 1 flag so
as to leave out the shearing.<br>

What you want is to apply a transformation called (at least
on the Matlab parlance) "Linear conformal" which an afine
transform but without the the shear terms. Mirone has it
implemented and if your image has the GCPS embedded the
operation is really simple.</font><br>

Thanks Joaquim, that's exactly what I meant. How can I use
Mirone's implementation?<br>

See the manual for example at (the program comes with a .chm
version too). Expand the "Image->Register Image" entry<br>
