Abstract To compare the performance of the three slope correction methods(the direct method, the indirect method and the relocation method), ERS1 data over the Vostok region in the Antarctic are processed based on the RAMP DEM model. The results show that the relocation method performs better than the other two methods. The accuracy of the direct method is the worst in the three methods.
