Information System City and Environment (ISU5) — Spatial Reference

Spatial reference geometry of the information system City and Environment (ISU). The demarcated ISU5 areas are closely related to the “Statistic Blocks of the RBS”, but differ in the block boundaries to the road country, in the formation of space units below the block plane, the so-called block sections, as well as road surfaces. The spatial reference of the city and environment information system (hereinafter ISU5) is updated annually as a priority update. The statistical blocks and usage changes are updated due to structural changes. The 5-year update, which uses a larger selection of specialised spatial data sets for real land use, can be found under “City and Environment Information System (ISU5) — Spatial Reference 2020”.
