WMS RP DOP40 Special Flight Floods: Orthophotos of Ahr Floods 2021

Ahr, Germany, is the geographic focus of this dataset. It provides digital orthophotos from a special aerial flight conducted in response to the 2021 floods. The data is delivered as a Web Map Service (WMS) and contains 3-channel RGB real-color raster images. The Bundesamt für Kartographie und Geodäsie (Federal Agency for Cartography and Geodesy) produced the dataset, which was last updated on March 23, 2026.

Use Cases

• Map flood extent and damage based on post-event aerial imagery.
• Analyze land cover changes caused by flooding using the RGB orthophotos.
• Create baseline geospatial layers for infrastructure recovery planning in the Ahr region.

Strengths

• Data adheres to the official German product and quality standard for digital orthophotos (adv-online.de).
• Imagery is from a dedicated special flight, likely providing timely coverage of the flood event.
• The dataset was last updated on March 23, 2026, indicating potential maintenance.

Limitations

• The exact spatial resolution, number of images, and total file size are unknown.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to its focus on the Ahr region in Germany.
