Yunnan-guizhou Plateau Region Lacks The Control Points Of The Geometric Correction Of Satellite Images

With the rapid development of Satellite remote sensing technology, high spatial resolution push broom linear CCD Satellite remote sensing image has been widely used. The common method of geometrical rectification need collect enough Ground Control Points which is well distribution. But at Yunnan-Guizhou plateau, with the relatively large height difference, ground control points are more than a little difficult to achieve, due to reasons like that the ground features are not obvious enough, or it is difficult for researcher to arrive there, or there is not enough time and so on. So it is of great significance to research on geometric rectification of satellite remote sensing image in conditions of lack of GCPs or without GCPs at Yunnan-Guizhou plateau.The previous research results is introduced at first. On the base of Systematic analysis of previous research results, tests are conducted based on SPOT5-1A and CBERS-02 level 1 imagery. SPOT5-1A image is certificated in the conditions of lack of GCPs and without GCPs by Erdas 9.2 LPS subject.M Moreover, an open source imagery processing library, is introduced to carry out the correct test with its command line utility, for SPOT5-1A and CBERS-02 level 1 imagery in conditions of lack of GCPs and without GCPs. On the base of these tests, a comparative analysis is conducted.On the condition of without GCP, it shows that the result of correcting the satellite remote sensing imagery with its auxiliary data is not good enough. Further study need to be carried out in the future. But in the condition of in lack of GCP, it is possible to positioning for ground, and has a good perspect.
