DSMs Extraction Methodologies from EROS-B “Pseudo-Stereopairs”, PRISM Stereopairs in Coastal and Post-seismic Areas

The aim of this paper is to illustrate a series of experimentations conducted on the possibility of extracting digital surface models (DSM) from stereoscopic images and from non stereoscopic pair of images that have a relative geometry similar to stereoscopic. The research is focused on imagery acquired from satellite platforms little or no investigated for this specific application field, such as ALOS-PRISM and EROS-B. Images acquired by both satellites on areas morphologically different between them, both in the Abruzzo region (Italy); some images represents a coastal area that spans from the city of Pescara to the city of Ortona, other represents the area of l’Aquila, whose history was marked recently by a series of earthquakes that caused serious damages also because the city is situated partially on an ancient lake-bed that amplifies seismic activity.
