Preliminary model of a part of a talus slope located in the Swiss Alps, Col Du Sanetsch (46°21’13”N 7°18’00”E, 2200 m a.s.l.). According to the Alpine Permafrost Index Map (APIM), no permafrost is present. Microtopography is visible on the slope, indicating the presence of some kind of snow niches. These niches are 5-10m wide approximately. The linear structure visible in the lower part of the slope, is a hiking trail. This model was reconstructed by using a camera stand of 7 m high and ground based photography. The model was georeferenced using detailed RTK GPS measurements (1-3mm) of 15 ground control points. Agisoft photoscanner was used to run the model. The result is a very detailed Digital Elevation Model (8 mm resolution). (45 photos taken by Panasonic Lumix DMC-GF7K + 12-32mm F3.5-5.6)
