The annual update mainly focuses on two things, i.e. the review and adjustment of the primary and meta-block boundaries of the ISU5 to new or updated statistical blocks of the RBS (defined by the Statistical Office for Berlin-Brandenburg, AfS), and the recording of changes in land use following structural changes. For this purpose, the AfS’s data on building completions and buildings with changed use, as well as data from the Housing Construction Space Information System (WoFIS) and the Commercial Area Information System (GeFIS) were used to identify areas to be reviewed due to new construction or demolition. In addition, a small number of areas was reviewed based on changes in the green space inventory.
In order to determine the actual use during the land use review, various specialised datasets were consulted, regarding, for example, building age, agricultural use or soil associations.
The annual update of the spatial reference of the Urban and Environmental Information System (ISU5) is based on the following resources.
