The paper concerns an in-depth study of the attainable accuracy of Leica ADS40 imagery. The study has been carried out with the Socet-Set and ORIMA programs and takes advantage of the Pavia Test Site, where many artificial and natural, very well measured control points are available. Three flights are considered, having a relative height of approximately 2000, 4000 and 6000 metres. Different configurations are investigated, characterized by the usage of 0, 1, 5 and 12 GCPs. Finally, several adjustment strategies are analyzed: together with the basic adjustment model, the usage of additional parameters (such as datum transformation and reestimation of IMU misalignments), as well as the camera self-calibration are taken into consideration.

Abstract
The paper concerns an in-depth study of the attainable accuracy of Leica ADS40 imagery.

Three flights are considered, having a relative height of approximately 2000, 4000 and 6000 metres. Different configurations are investigated, characterized by the usage of 0, 1, 5 and 12 GCPs. Finally, several adjustment strategies are analyzed: together with the basic adjustment model, the usage of additional parameters (such as datum transformation and reestimation of IMU misalignments), as well as the camera self-calibration are taken into consideration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
