Multi sensor photogrammetric techniques for the documentation of the ruins of Temple G in Selinunte

In the past two decades UAV have been increasingly used for the survey of wide areas. The chosen case study, the huge heap of ruins of the Temple G in Selinunte, demands a higher accuracy than that usually accepted for wide areas survey; nonetheless, the morphology of the ruins makes laser scanning survey inadequate to the purpose of the analysis and interpretation. The proposed methodology integrates SfM photogrammetry from UAV and action camera’s photos. A test on a specific area has evaluated the accuracy of photogrammetric survey through the comparison with laser scanning data.
