Aiming at remote sensing images of less ground reference point

we discuss a new geometric exact correction method in this paper. The method applies the theory of space map projection to geometric exact correction of remote sensing images

using spatial oblique mercator projection theory and a few ground reference points to do the geometry exact correction of images. The method is of strictness theory and rapidness arithmetic throughout the experiment of TM image of Guangzhou region

the precision of exact correction is less than one pixel.
