Geoinformatics is concerned with the acquisition, representation and analysis of spatial data using informatics and geostatistical methods. This includes almost everything that has to do with the questions 'where?', 'where to?', 'how big?' but also 'how is it here?' or 'is it possible there? Geoinformatics uses not only geodata from the neighbouring disciplines of terrestrial or remote sensing surveying, but also semantic, i.e. topic-related data. By synoptic analyses of geometry, topology and semantics, the planning of a building or the evaluation of an environmentally relevant impairment is possible under consideration of certain conditions, such as legal requirements. The access and analysis of the data is increasingly spread over the Internet.
The AG Geoinformatik at the IGP is particularly concerned with the planning support of the energy transition and the urban ultra-fine dust pollution that has become a matter of public interest due to the Diesel affair. Since the source data is increasingly available in distributed form on the Internet, the corresponding methods for exchanging the data are also considered. This research and development is perfected by the work on the international OGC standard CityGML for semantically attributed 3D city models.
