High-Resolution Alpine Drone Photogrammetry from Davos

Four drone flights over the Wolfgang Arelen site in Davos captured imagery for generating detailed 3D surface models. The data was processed using Agisoft Metashape Professional Software. Flights were conducted by ENVIDAT across the 2020/21 and 2022 winter seasons.

Use Cases

• Generate centimeter-resolution digital surface models (DSMs) from overlapping drone imagery for terrain analysis.
• Create orthomosaics for land cover classification and change detection in the Wolfgang Arelen alpine region.
• Validate snow depth or glacier mass balance models by comparing DSMs from the 2020/21 and 2022 flight campaigns.
• Benchmark photogrammetric software performance using the Agisoft Metashape-processed reference data products.

Strengths

• Data from four distinct drone flight campaigns provides multiple temporal snapshots.
• Processing with professional-grade Agisoft Metashape software suggests structured output products.

Limitations

• Unknown sample size and spatial extent of the four flights limits assessment of coverage.
• Lack of column details or sample data prevents evaluation of data structure and accessibility.
