GIScience / Geoinformatics Research Group
Essential parts of the research focus of the GIScience research group (Geoinformatics) are reflected by the PhD graduate school (Research Training Group, RTG) (CrowdAnalyser) (Speaker: Prof. A. Zipf). This group consists of several PhD students and postdoctoral researchers, who investigate the quality and usage potential of user-generated content (UGC). The main focus is on Volunteered Geographic Information (VGI). We develop new methods for spatio-temporal analysis of data sources such as OpenStreetMap or Social Media and other Web 2.0 projects, ranging across Twitter, Flickr to all kinds of geo-social networks. Several applications and services built on these evolving data sources demonstrate the feasability of their usage in different domains. Additionally, new methods for crowdsourced 3D geoinformation are being developed.
Beside of investigating VGI, the research group has a strong focus on 3D geo-information. Corresponding research areas comprise data acquisition and retrieval using state-of-the-art “3D remote sensors” such as laser scanning (i.e. topographic LiDAR) enriched by other potential sources such as crowdsourced data provided by “human sensors”. The primary focus here is the development of GIS-based algorithms for 3D data processing and analysis in order to improve the understanding of geographical phenomena. Applications cover the natural environment (e.g. geomorphology, precision farming and forestry) and the man-made landscape (e.g. Archeology and digital cultural heritage, solar potential assessment for buildings and hedonic price modeling using 3D laser data).
Junior. Prof. Bernhard Höfle leads the work on 3D processing and LiDAR research. In addition to the 2 professors, two Klaus-Tschira Incubator Research Groups "Advancing GIScience" have been established:
Dr. Bernd Resch leads the Klaus-Tschira Incubator Group on "Live Geography" and Dr. Hongchao Fan leads the Klaus-Tschira Incubator Group on "3D Urban Modelling". Further PostDocs coordinate additional research lines, such as "Smart Simulation" by Dr. Bakillah.
The research of the group also deals with the investigation and development of new web-based geographic Information Services (GIS) in different application domains such as disaster management, eHumanities, agriculture, traffic, energy and environment. The research extends conventional spatial data infrastructures (SDI) by adding the third dimension (3D city models and 3D landscape models, GDI-3D.de), location based services (LBS, in particular specialized applications in routing- , navigation and traffic management), dynamic sensor data and of course web-based geoprocessing and geographic analysis functionalities.
Selected services can be discovered online (e.g. OpenRouteService.org, OSM-3D.org, OSMatrix.uni-hd.de, OSM-WMS.de, OpenMapSurfer.uni-hd.de, RollstuhlRouting.de, HistOSM.org etc.).
