  • Catchment areas of the drainage system of the Berlin Waterworks, as of October 2022 (BWB 2022a),
  • Type of drainage of road areas, analysis by the Berlin Waterworks, as of October 2022 (BWB 2022b),
  • Urban and Environmental Information System (ISU5) – spatial reference 2020, as of Decemeber 31, 2020 (SenSBW 2022),
  • Actual Use of Built-up Areas / Inventory of Green and Open Spaces 2020, as of December 31, 2020 (cf. Environmental Atlas 06.01, 06.02 SenSBW 2020a) and
