Accuracy Assessment of 2D and 3D Geometric Correction Models for Different Topography in Iraq

Abstract

In recent decades, Remote sensing data becomes one of the basic information required for mapping and different applications in geomatics. In this research, different mathematical models in 2D and 3D cases are investigated and comprised in order to assess the accuracy of these models under different conditions of terrain topography. Three high resolution satellite QuickBird images of three different study areas, with respect to their topography have been used in this work. In this research, the 2D mathematical models which were used, 1st, 2nd order polynomial, and projective transformation model while, the 3D mathematical models used were, 1st, 2nd order 3D polynomial, and direct linear transformation model. All these methods are applied for each study area and evaluated through the Matlab environment facilities
