Encouraging accuracy of better than 1.1 m in planimetry and 1.5 m in height can be achieved from the pre- and post-seismic IKONOS stereo image pairs using the affine model based on the RPC bundle adjustment. Even in case of one GCP, accuracy better than 2 m in planimetry and 2.5 m in height can be achieved. This is the basis for the subsequent successful detection based on the IKONOS stereo image pairs.
