A MATLAB-based program has been written to perform the required computation by two methods, namely, "iterative model" and "non-iterative tilt photo-generator equation". With a Standard error of 10.77m, 10.77m, and 279.31m for the Xo, Yo, and Zo, respectively, the "Non-iterative Tilt Photo Generator Equation" Model was chosen as a better fit for the Solution, although the accuracy achieved is unacceptable for higher-order survey tasks. This therefore confirms that stereo images are better suited for higher-order survey tasks.enGround Control Points (GPs)Oblique PhotographsCollinearity Equationexterior orientation parametersArticle
