Abstract: A method of the block adjustment based on a new strict geometric model for remote sensing images with high resolution (RSIHR), using few control points, is presented in this paper. The model has been tested for IKONOS and other RSIHR. The block adjustment based on RPC parameters with IKONOS images has been tested and compared with the new strict geometric model. All the tested result shows that the accuracy of the new model can reach the level corresponding to the ground resolution of the images with few control points.
