“…Data on sealed surfaces (ratio of sealed area to municipal area) were provided by the IÖR Monitor on Settlement and Open Space Development since 2013 [73]. We have given an overview of the steps needed to derive the indicator degree of soil sealing.…”

“…For example, the SEMENTA ® (Settlement Analyzer) system developed at the Leibniz Institute of Ecological Urban and Regional Development can be used to analyze the morphology of building stock as well as to calculate various indicators describing the built environment such as building density, building coverage ratio, floor-area ratio, and housing or population density at urban block level, with resulting data visualized within a GIS [1]. It is intended to make the results freely available within the framework of a web-based information system for monitoring land use in Germany (www.ioer-monitor.de) [3]. The basic input data is in the form of building footprints taken from digital topographical data of cadastral land registers (in Germany: ALK, ALKIS ® ) or national topographic surveys (in Germany: ATKIS ® Base DLM).…”

Due to financial or administrative constraints, access to official spatial base data is currently limited to a small subset of all potential users in the field of spatial planning and research. This increases the usefulness of Volunteered Geographic Information (VGI), in particular OpenStreetMap (OSM), as supplementary datasets or, in some cases, alternative sources of primary data. In contrast to the OSM street network, which has already been thoroughly investigated and found to be practically complete in many areas, the degree of completeness of OSM data on buildings is still unclear. In this paper we describe methods to analyze building completeness and apply these to various test areas in Germany. Official data from national mapping and cadastral agencies is used as a basis for comparison. The results show that unit-based completeness measurements (e.g., total number or area of buildings) are highly sensitive to disparities in modeling between official data and VGI. Therefore, we recommend object-based methods to study the completeness of OSM building footprint data. An analysis from November 2011 in Germany indicated a completeness of 25% in the federal states of North Rhine-Westphalia and 15% in Saxony. Although further analyses from 2012 confirm that data completeness in Saxony has risen to 23%, the rate of new data input was slowing in the year 2012.

“…As shown by Krüger et al [28], linear objects of transportation and hydrological networks have to be buffered in order to get a polygon representation of these features. Since most of the buffered objects are still narrow with respect to the structure elements that are applicable to polygon objects, the corrected opening procedure would end up in a broad elimination of features.…”

“…Otherwise, the portion of the Earth's surface that is covered by transportation infrastructure and water bodies would be heavily underestimated. Buffered features always override the land use information of their neighboring polygons [27][28][29]. A major issue of the Basic DLM is the varying topicality of the data due to the updating cycles, which is realized by updating tiles comparable to a traditional mapping sheet division, of the mapping agencies, which can cause topicality differences of several years.…”

Abstract:The implementation of sustainable land policies is in need of monitoring methods that go beyond a mere description of the proportion values of land use classes. The annual statistical surface area report on actual land utilization (German: "Bodenfläche nach Art der tatsächlichen Nutzung"), published by the statistical offices of the German federal states and the federation, provides information on a set of pre-defined land use classes for municipalities, districts and federal states. Due to its surveying method of summing up usage information from cadastral registers, it is not possible to determine previous and subsequent usages of land parcels. Hence, it is hard to precisely indicate to what extent particular land use classes contribute to the settlement area increase. Nevertheless, this information is crucial to the understanding of land use change processes, which is needed for a subsequent identification of driving forces. To overcome this lack of information, a method for the spatial and quantitative determination of previous and subsequent land usages has been developed, implemented and tested. It is based on pre-processed land use data for different time slices, which are derived from authoritative geo-topographical base data. The developed method allows for the identification of land use changes considering small geometric shifts and changes in the underlying data model, which can be adaptively excluded from the balance.
