The paper describes the results of photogrammetric survey of Ponte Rotto (literally, Broken Bridge), a Roman bridge on the ancient Appia way close to Benevento (southern Italy). The photogrammetric survey was carried out by means of a DJI Phantom 4 with a 12 Mpixel camera. One nadir and two side flights allowed obtaining 273 images and placing 6 Ground Control Points. A 3D model with a 8 millions points cloud was constructed (average error < 4 cm and Ground Simple Distance < 7 mm). The extrapolated ortho-photos were used for quantitative evaluation of lithotypes and damage diagnosis performed by Fitzner and Heinrichs method.

Abstract
The paper describes the results of photogrammetric survey of Ponte Rotto (literally, Broken Bridge), a Roman bridge on the ancient Appia way close to Benevento (southern Italy). The photogrammetric survey was carried out by means of a DJI Phantom 4 with a 12 Mpixel camera. One nadir and two side flights allowed obtaining 273 images and placing 6 Ground Control Points. A 3D model with a 8 millions points cloud was constructed (average error < 4 cm and Ground Simple Distance < 7 mm). The extrapolated ortho-photos were used for quantitative evaluation of lithotypes and damage diagnosis performed by Fitzner and Heinrichs method.File in questo prodotto:
