An intense activity of archaeological photo-interpretation was demanded to investigate such main topographic features and it was carried on at DILBEC by following peculiar methodologies proper of the aerotopographic research led in a 3D environment and on different targets: historical, aerial vertical frames; digital aerial frames; recent satellite images having a geometric resolution appropriate for the main goals of this research.

Interpretation of topographic features has revealed interesting archaeological evidence, fakes and visible features with peculiar characteristics such as shape, color, tone, dimension, texture, their characterization being essential to a correct interpretation.
At the same time, the editing of an original digital cartography was completed at the DILBEC laboratory. This was necessary for both archaeological and geological advanced studies. Digital cartography was acquired in a pure digital environment through a photogrammetric workstation designed for cartographic restitution. Since elevation anomalies were to be evidenced, the photogrammetric restitution was finalized to render the topographic setting of geographical features, keeping a 5-meters main contour interval and a 1-meter secondary contour interval.
