High-Resolution Drone Imagery and Snow Depth Models of Dorfberg

10 drone flights captured both summer and winter conditions over the Dorfberg area using a Wingtra Gen II drone and Sony sensor. The dataset provides a 10cm resolution Digital Surface Model and 3cm resolution orthophoto for each flight, alongside derived snow depth rasters. Data was collected by ENVIDAT and made available via NASA EarthData, with a last recorded update in 2022.

Use Cases

• Calculate seasonal snow depth changes by differencing the Digital Surface Model (DSM) rasters from summer and winter flights.
• Train semantic segmentation models to classify terrain features using the 3cm resolution orthophoto imagery.
• Validate satellite-derived snow products by comparing them with the high-resolution snow depth raster data.
• Generate 3D terrain reconstructions for the study area by processing the original drone images through photogrammetric software.

Strengths

• Includes 10 distinct flight campaigns providing multiple temporal snapshots.
• Offers very high spatial resolution with a 10cm DSM and 3cm orthophoto.
• Contains both raw drone images and processed raster products (DSM, orthophoto, snow depth).

Limitations

• Specific sample size, geographic extent, and data volume are unknown.
• Data is from 2022 or earlier, potentially lacking recent seasonal observations.
• Limited to a single geographic location (Dorfberg), reducing generalizability.
