Key characteristics of section types

A differentiated definition and description of section types can be found in the report on Dokumentation der Kartiereinheiten und der Aktualisierung des Datenbestandes 2010 (German pdf; 7,6 MB) (Documentation of mapping units and updating of the data base). There, particular mapping units of the section types are described in detail with reference to particular representations. Each particular representation contains:

  • a text description
  • the mapping rules
  • information as to how many sections are included in the respective category
  • information on building age, provided characteristic statements can be made in that regard
  • information on key characteristics
  • exemplary representations showing the distribution of the block sections in the urban area, a section from the K5 (Berlin map, scale of 1:5.000), a section from the digital orthophotography (Orthophotos, aerial survey April 2009), and ground-level photos of typical blocks, as well as
  • where appropriate, notes on changes in content undertaken since the last revision.

The key characteristics in each case includes the arithmetic mean and the typical range of values for the following quanta:

These quanta are the factual data available in the data bases which are regularly generated in the City and Environment Information System, with the block map as the spatial reference. The statements contained in the brief descriptions were calculated according to the current use maps by statistical evaluation. In order to ascertain the range, the lower limit was given as the 5th percentile, and the upper limit as the 95th percentile, in order to avoid including atypical outliers. In exceptional cases, there are indeed therefore sections which fall outside these characteristic ranges (10% of sections).

In the context of the revision, automated plausibility checks were carried out on the basis of key characteristics, and exceptional sections were visually examined. For the statistical evaluation, only those sections could be used the geometry of which had not been changed with respect to ISU-5 2005. For the new areas, the necessary data were not yet available.

The following table shows the key values ascertained by statistical evaluation for a selection of section types (section types of Groups I through III). For example, it shows that the dense block construction with closed courtyards is the most densely inhabited section type, with an average resident density of 487 inh./ha. The high use intensity of core areas can be seen from the high average floor space indices.

A differentiated definition and description of section types can be seen in the report on the documentation of mapping units and the updating of the database. There, the particular section types are described in detail.
