Abstract
In the present paper the phases of extraction of a DSM from Prism stereopairs and triplets are illustrated. PRISM was a panchromatic radiometer carried onboard the Japanese remote sensing satellite ALOS (Advanced Land Observing Satellite); this work has mainly a methodological value cause on May 12, 2011, a command was sent to stop the onboard transmitter and now the sensor is no more operative. The sensor had three optical systems for forward, nadir and backward views with 2.5 meter nominal spatial resolution. Multiple Linear Array CCD chips were located on the focal plane of each camera, along one across-track line. Images here studied represent a coastal area that spans from the city of Pescara to the city of Ortona (both in Abruzzo region, Italy). The availability of PRISM stereopairs and triplets is not widely studied and in this paper accuracy of produced DEMs is compared with heights from terrestrial Lidar survey on the area of the city of Pescara (Abruzzo region, Italy). Extraction was executed with Geomatica 2012 using rigorous model, with GCPs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
