This API provides soil profile data for Hamburg, published by LGV Hamburg (State Office for Geoinformation and Surveying). Soil profiles describe vertical cross-sections through soil bodies taken from the earth's surface. From these profile cuts, various soil horizons, soil type, and other soil parameters can be determined. The geodata is provided as a WMS visualization service, accessible via a WFS interface for querying and retrieving the underlying features.Die Bodenprofile beschreiben die von der Erdoberfläche aus erfolgten senkrechten Schnitte durch Bodenkörper. Anhand der Profilschnitte können die verschiedenen Bodenhorizonte, der Bodentyp und weitere Bodenparameter bestimmt werden. Die Geodaten werden als WMS-Darstellungsdienst bereitgestellt.
