This paper presents a method that has been developed for creating perspective relief images capable of extracting measurement information as a feature of the distance from the observation post. This method 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 based on the digital terrain model of the area and the shaded view of the same relief. The method is applied in the Lefka Ori mountain range in Crete, and the results are compared to actual photo shootings in the same area. The digital relief visualization can assist in better comprehending the three-dimensional space and in efficiently managing the visual environment.
