In utilizing satellite imagery, the Rational Function Model(RFM) simplifies the geometric relationship between image coordinates and ground targets. In this study, the RFM model for KOMPSAT-5 was generated and evaluated. The general least squares adjustment and Tikhonov regularization in the RFM generation process were applied to calculate the RFM coefficients. The virtual grid was generated using the physical sensor model for KOMPSAT-5 and used as control points to calculate the RFM coefficients. As a results, the virtual grid size did not show significant improvement from 7x7. In addition, the analysis result according to the number of the elevation layer was obtained sufficiently stable result even at 10x10x5.
