Abstract:The geometric process of MODIS image is a kind of basic research work and is a key step before the utilization of data. In view of the fact that the large scanning angle of MODIS and the earth’s curvature lead to the overlapping and dislocation, this paper deals in detail with high precision location and geometric correction for MODIS data. Based on a comparative study of the advantages and disadvantages in some overlapping removing algorithms, the author presents the direct method and direct-indirect method which can remove overlap in geometric correction. It is proved that the two kinds of resampling methods are feasible, and the precision of geometric correction can basically meet the requirement. Thus, the real image geometric character is rebuilt.
