INVESTIGATION OF GEOMETRIC ERRORS PROPAGATED BY TRANSFORMATION MODELS ON HIGH RESOLUTION IMAGE

ABSTRACT: The usages of satellite images are intruding many fields of geoinformatics researches and applications. Image registration and image mosaic are the first step of integration of images. However, sensing sensors ’ interior/exterior orientations errors are corrected by the sensor technology; some geometric errors are propagated to image products based on transformation models and earth surface terrain. The study will be investigated the geometric errors on satellite images using transformation models: 3D projective model, separated 3D projective model and 3D affine model. Error trends will be appeared based on terrain and models. In other hand, new geodetic survey technique, VRS-GPS Ground Control Points, will be used to register images. As theory, the VRS-GPS could produce GCP with centimeter level accuracy. As result, 3D affine is suggested transformation model amount basic models. 1
