For the time period 2011-2016, this method reveals an increase of 1,869 km² in settlement area and transport space, primarily on land previously used for agriculture (77%) or areas of woodland and bushes (19%).
|Previous usage||Area [km²]|
|Increase in settlements and transport space||1869,0|
Detailed analysis shows the ratios for subtypes of newly created areas for settlement and transport. Within the new SuV areas, the built-up areas predominate at 66%. Transport space account for 23% and urban open space for 11%.
Direct comparison of the input data to the IOER Monitor at diverse time points (processed ATKIS Basis-DLM) enables the unambiguous classification of changes in land use at the level of settlements. In this way we can quantify those forms of usage which are named when converting land for settlement and transport development.
The method is based on a geometrical intersection while taking account of tolerances at object edges.
In this way it is possible to prevent incorrect classifications due to the shifting of polygonal vertices which can occur through minor changes in position when data is updated (splitter polygons).
The indicators on consumption of new land are based on this method, and permit an estimate of the extent of converted land parcels.
