The graduation thesis evaluates the aerotriangulation methods and gives an example of a SocetSet software usage in photogrammetric data collection for aerial triangulation. Traditional aerotriangulation is time consuming method because it requires manual determination of tie points. On the other hand it ensures high accuracy and reliability of results. The development of image matching techniques enabled automatic approach to aerotriangulation where tie points are measured in automatic or semi-automatic mode. With the advent of GPS in the 80’s of the 20th century, this technology was used to determine the projection centres of images. Today GNSS/INS integration in direct sensor orientation provides determination of all exterior orientation parameters without the need of ground control points. Integrated sensor orientation provides higher reliability of results, because GNSS/INS observations are only used as the additional parameters in aerotriangulation. This is the
reason why indirect sensor orientation is still used in high accuracy demanding photogrammetric projects. SocetSet digital mapping software is used for aerotriangulation of large blocks of images. The graduation thesis presents the process of automatic aerotriangulation in SocetSet software in an practical example, where image coordinates of tie points are measured automatically. Because this software does not enable bundle block adjustment on appropriate level, we processed it with AeroSys software. This software allows us many different models of adjustment and easier detection of gross errors as well as interpretation of aerotriangulation accuracy.
