Information System City and Environment (ISU5) — Spatial Reference

Reference geometry of the information system City and Environment (ISU). The ISU5 areas are closely related to the “Statistic Blocks of the RBS”, but differ in the block boundaries to the road country and by forming block sections as a level below the block plane. They are updated annually on the basis of statistical blocks and usage changes. The more comprehensive 5-year update can be found under “City and Environment Information System (ISU5) — Room Reference 2020”.
