In addition, the classic software tools, implemented for frame cameras, need to be adapted to cope with modified aerial triangulation and self-calibration procedures. This contribution presents the results obtained from the geometrical analysis and self-calibration of the second-generation pushbroom ADS40 camera, the SH52. For this purpose, a testfield was designed and built on the outskirts of Ávila, Spain and two blocks, flown at different heights, were imaged. A wide network of well-defined control and check points was observed in order to provide a thorough assessment of the accuracy and reliability of the camera. Empirical analysis of a variety of models within aerial triangulation as well as the use of internal camera parameters has led to an evaluation of the camera's performance in a real-life environment.
