Corinth terraces re-visited: Improved paleoshoreline determination using Pleiades-DEMs

Abstract : The newest generation of satellites have greatly improved the capabilities of optical imagery over the last decade. Ground resolution has increased by one order of magnitude (to sub-metric pixel images), and improved sensors allow images to be located with an absolute accuracy of within a few meters. Better-resolved images facilitate refined tectonic studies of faults, basins, terraces, and other geomorphic features as it provides the opportunity to extract detailed topographic information. We have developed high-resolution digital elevation models (DEMs) in eight locations in Greece from tri-stereo satellite images acquired by the new Pleiades platform of CNES. With 0.5m resolution, these DEMs are state-of-the-art in comparison to previous DEMs made from satellite imagery. In this study we explore the potential of one of these DEMs, in the eastern Gulf of Corinth, for the analysis of a flight of marine terraces.
