Aerial triangulation is the most important, and vital, part of this project and will be performed using the Match-AT module of INPHO photogrammetry suite. Interior orientation (IO) will be established using camera calibration report. The initial approximate exterior orientation (EO) will be established using the Airborne Global Positioning System (AGPS) and Inertial Measurement Unit (IMU) data acquired. The ASPRS class I standards will be input as parameters with weight constraints. Tie points and control points will be measured manually. Tie points extraction and correction are done automatically and the final results are checked for distribution, number and completeness of the observations. Final AT solution will be computed and it will be refined further using Bundle block adjustment module. The final solution also will be delivered in prescribed formats. After acceptance of the AT solution SBL will move towards the next stage of the project.

We deliver AT results in various industry standard formats like PATB, Bingo, BLUH,
