520 $a Aspects of reliability, and precision, as well as practical considerations, for an airborne GPS-photogrammetry system were also investigated.
520 $a Aerial Triangulation (AT) has been used for mapping purposes for a long time to provide 3D coordinates of object points on the ground. This technique uses series of overlapping photographs, and some control points, in order to establish the relationship between the image coordinate system and object coordinate system. In the process of bundle block adjustment, image coordinate observations and coordinates of the ground control points are simultaneously adjusted and the exterior orientation parameters, as well as the ground coordinates of all tie and pass points, are estimated. One of the biggest challenges in AT is to reduce the number of control points. One effective way is to directly measure the exterior orientation parameters of the camera at the time of exposure.
520 $a Airborne kinematic GPS (Global Positioning System) provides a means of determining the position of the aerial camera at each instant of exposure. The combined GPS-photogrammetric block adjustment takes advantage of weighted GPS observations, which significantly reduces the number of ground control points needed in a conventional block adjustment.
520 $a A comprehensive software package, GAP (General Adjustment Program), was developed in this research to effectively integrate and adjust GPS, geodetic, and photogrammetric observations. Optimization of the GPS-photogrammetric bundle block adjustments for both simulated large scale mapping and real medium scale mapping was carried out.
520 $a GPS coordinates of the camera exposure stations do not permit recovery of the roll angle of the aircraft in a GPS single strip triangulation. Therefore, ground control points are still required in addition to the GPS coordinates of exposure stations to overcome this problem, and to eliminate singularity of the normal matrix in the least squares adjustment.
520 $a A new technique for GPS single strip triangulation using geometric constraints of man-made structures (e.g., high voltage towers) located along the flight line was proposed, and successfully implemented on real data. This new technique eliminates the need for multiple strips of photography, which has been adapted conventionally to recover the roll angle. The time and the cost of corridor mapping projects are significantly reduced by incorporating this technique.
