This Web Feature Service (WFS) provides gridded data on heavy metal concentrations in topsoil for the southeastern part of Hamburg, an area historically and currently influenced by industrial activity. In the past, heavy metals were deposited on surface soils largely through airborne transport. Since these substances do not degrade, elevated concentrations can still be found in the soil today. The dataset is published by LGV Hamburg (Landesbetrieb Geoinformation und Vermessung) and can be accessed via a standard WFS interface, supporting environmental monitoring, soil quality assessment, and urban planning in the region.Der Untersuchungsraum liegt in einem Gebiet, das nachweisbar von der vorhandenen Industrie beeinflusst wurde und wird. Insbesondere in der Vergangenheit gelangten u.a. Schwermetalle über den Luftpfad auf die Oberböden. Da sich diese Stoffe nicht abbauen, sind auch heute noch erhöhte Gehalte – vor...
