Aerial triangulation is a mathematical process of establishing precise and accurate relationships between the images coordinate system and defined datum and projection on the ground. The main objective of aerial triangulation is to produce from ground control point and any other sufficient points in the photogrammetric model to make sure for each model can be oriented accurately as required for stereopair compilation in either orthophoto or line mapping. The process uses all possible overlaps image with a few number of reference points. There are mainly three stages of aerial triangulation, one of them is preparation by making point identification of ground control point, numbering of points, images and strips, and the flight details such as photo coordinate, camera calibration and scanned or digital images. Second, Interior orientation is important to relate aerial image to the object on the ground which used to determine the fiducial marks measurement for cameras. Then, relative orientation is made followed by block adjustment where it includes algorithm for determination of blunders and error propagation.
