Estrazione di DSM da immagini del satellite Eros B acquisite in stereoscopia: studio preliminare nell'area di Benevento

In this paper the results of a preliminary test of Digital Surface Model (DSM) automatic extraction made on a pair of stereo images satellite Eros B was discussed. The test was carried out on images Eros B for a peripheral area of Benevento. The extraction of DSM was made using a commercial software PCI Geomatics 10.1.2 equipped with an model orbital of the Eros B satellite. The data used for the operations of the acquisition and validation of DSM were obtained by mapping CTR 1:5.000 scale. A DSM with step grid 1.4 metres showing values of accuracy on heights estimated at around 2 metres has been produced.
