UAV-derived Digital Surface Models and orthoimages for three alpine glaciers

Between 2015 and 2016, Unmanned Aerial Vehicle (UAV) surveys were conducted on the Sankt Annafirn, Findelen-, and Griesgletscher in the Swiss Alps. The dataset contains high-resolution orthoimages and Digital Surface Models (DSMs) at 0.1-meter resolution, produced by the ENVIDAT organization and documented in a 2017 publication.

Use Cases

• Monitoring glacier surface elevation changes over time based on the multi-temporal Digital Surface Models.
• Analyzing glacier morphology and features using the high-resolution orthoimages.
• Validating satellite-derived elevation products against UAV-acquired surface models.
• Assessing photogrammetric processing accuracy for UAV surveys on glacial terrain as referenced in the associated paper.

Strengths

• Data has a very high spatial resolution of 0.1 meters per pixel.
• Surveys were conducted over multiple years (2015-2016) on three distinct glaciers.
• Products are precisely georeferenced using Ground Control Points measured with differential GPS.
• A peer-reviewed publication (Gindraux et al., 2017) provides detailed accuracy assessment.

Limitations

• Last updated 2017-01-01 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• The spatial coverage is partial for the Findelengletscher, as noted in the description.
