Abstract: LANDSAT MSS COT data was generally rtecti’xied by polynomials, hardly thinking over the geometric characters, the residual error and ite well-distribution’depend on the ground control points and its distribution.In this study, we use the co-lineal equations in traditional photogrammetric as the mathematic foundation. The traditional photogrammetric single point rosection in space of a frame photography, here degenerates as the frame is substitutes by a line. The sa-tellite orientation elements is the function of scanning time (or scanning line). The mathematical model has been established between the image pixels and the ground tar-gets. We have also developed the corresponding software. The utility of the theory and software mentioned above was proved by experiment.
