An algorithm for digital relief visualisation capable for extracting measurment information and using GIS technologyAn algorithm for digital relief visualisation capable for extracting measurment information and using GIS technology Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-192006enThis paper presents an algorithm that has been developed for creating perspective relief images, capable of extracting measurement information as to the feature of distance from the observation post. This algorithm produces a perspective image of the relief, as the latter would look if it was photographed from a known shooting point in relation to a target point, using a photo camera of known geometry, and taking as granted the digital model of the area's ground and the shaded view of the same relief. The algorithm is applied in the Lefka Ori mountain range and the results are compared to actual photo shootings in the same area.http://creativecommons.org/licenses/by/4.0/ Geocarto International12171-76 Tsouchlaraki Androniki Τσουχλαρακη Ανδρονικη Taylor & Francis APS (Advanced Photo System) advanced photo system aps advanced photo system
