| Summary: | Plan da Mattun is located at ~2200 metre above sea level in the Tasna valley in alpine south-eastern Switzerland. In this remote
location, finds dating back to the time of Ötzi (3000 B.C.) were discovered by archaeologists from the University of Zurich. For
detailed investigations of the site as well as for documentation and visualization purposes the archaeologists were interested in digital
models of the terrain and of certain boulders. In the presented project a digital terrain model of the rock stream located at the
beginning of the valley was created, as well as detailed models of four larger boulders. These boulders average to 15 metre in height
and width. The roughness of terrain makes it difficult to access certain areas and requires using multiple surveying techniques in
order to cover all objects of interest. Therefore the digital terrain model was acquired using a combination of terrestrial laser
scanning (TLS) and photogrammetric recording from an unmanned aerial vehicle (UAV). The larger boulders were reconstructed
with a combination of TLS, terrestrial and UAV-based photogrammetry. With this approach it was possible to acquire a highaccuracy
dataset over an area of 0.12 km<sup>2</sup> under difficult conditions. The dataset includes a digital terrain model with a ground
sampling distance of 10 cm and a relative accuracy of 2 cm in moderately sloped terrain. The larger boulders feature a resolution of
1 cm and a relative accuracy of 0.5 cm. The 3D data is to be used both for archaeological visualization purposes and for geological
analysis of the rock stream. |
