摘要：This particular study deals with the development of a Generic model called Rational Polynomial Coefficient, which relates the object space with the image space thereby, georeferencing a satellite image. For the purpose of georeferencing Cartosat-1 Leader file has been used. Ephemeris or the space positional coordinates and the attitude angles, which are a function of time, are extracted from the Leader file. The image coordinates and the corresponding ephemeris coordinates are used to derive the ground coordinates with the help of the physical model (Collinearity equation). The unknown Rational Polynomial Coefficients are obtained by developing a Rational function between the image row, column and the corresponding ground coordinates. From the calculated Rational Polynomial Coefficients, the ground coordinates are derived using the Rational Function. The geodetic height for the corresponding ground coordinates are input from the Shuttle Radar Topographic Mission 90 meter Digital Elevation Model. Then Root Mean Square Error is obtained between the calculated ground coordinates and those obtained by ground survey
