Abstract :
The production and accuracy analysis of high quality TerraSAR-X DOM are presented. The main focus is given to how to control the accuracy of ortho-rectification framework. Two SpotLight scenes of 1 meter resolution images and two ScanSAR scenes of 3 meter resolution images in China are used as the experimental data. Based on the proposal ortho-rectification framework, the absolute accuracy of TerraSAR-X DOM can reach to less than three pixels.
