[gdal-dev] Warping without shear

[Jan Hartmann]

Hi all,

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? Control points will be way off, of 
course, but I am interested in the original forms of the mapped items.
