In this study two blocks of KOMPSAT-5 L1A standard mode images were used to study the geometric modeling accuracy of the images both with and without GCPs. The first set is a block of four images of the city of Ottawa, Ontario, Canada. The second set is a block of 9 images of Kelowna, British Columbia, Canada. PCI OrthoEngine software was used to perform the evaluation process.  Since KOMPSAT-5 L1A data is distributed with RPCs, RPC geometric modeling method was used for the study.
