In the experiment, two stereo IKONOS-2 panchromatic images of one of the Cracow city districts were used. They were acquired by the Satellite Center of Regional Operations (SCOR) in Komorow, Poland in May 2005, with time interval of 1 minute. The stereo images used in this experiment had been reprocessed by the cubic convolution resampling, due to spatial and radiometric resolution. The images were delivered with RPC coefficients and file of metadata with all detailed information. The part of Cracow area selected for photogrammetric stereo compilation is shown in figure 2.
