In remote sensing data, geometric distortions are observed due to acquisition system and the movements of the platform. A geometric correction of the image is required whenever the image is to be compared with existing maps or with other images. This review paper enlists various Preprocessing techniques for geometric correction of raw images. Preprocessing of satellite image is prerequisite for further analysis applications such as change detection, object identification, image classification etc.
