sketchfab

Preliminary prototype of a segment of a talus slope situated in the Swiss Alps, Col Du Sanetsch (46°21'13"N 7°18'00"E, 2200 m above sea level). According to the Alpine Permafrost Index Map (APIM), no permafrost exists. Elevation changes are visible on the slope, indicating the presence of various types of snow shelters. These shelters measure approximately 5-10 meters wide. The linear feature apparent in the lower part of the slope is a hiking path. This model was recreated by utilizing a camera stand measuring 7 meters high and ground-based photography. The model was georeferenced using precise RTK GPS measurements (1-3 millimeters) of 15 ground control points. Agisoft photoscanner was utilized to process the model. The outcome is an extremely detailed Digital Elevation Model with an 8 mm resolution. (45 photographs taken by Panasonic Lumix DMC-GF7K + 12-32mm F3.5-5.6)
