GIScience / Geoinformatics Research Group
Essential parts of the research focus of the GIScience research group (Geoinformatics) http://giscience.uni-hd.de 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 projects 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. Further research topics and domains of interest see below

We are happy to report that our task designed for the citizen science platform crowdcrafting.org was selected as their #ProjectOfTheWeek. This will help us to finish our experiment to derive information about sidewalks using Mapillary street level imagery with the support of the crowd very soon. Sidewalk information is an important resource for accessible route [...]
A full-time PostDoc position is available at the GIScience Research Group at the Department of Geography of Heidelberg University. The aim is to contribute to the research at the GIScience Research Group and to start building an own junior research group including the mentoring of PhD students. The candidate should have a demonstrated research track in at [...]
On friday 3/13, Melanie Eckle, Steffen John and Stefan Hahmann of the GIScience group Heidelberg were invited to a special event at Mannheim town hall. The city of Mannheim showed appreciation to the engagement of the GIScience group during the Open Data Day in Mannheim. Melanie Eckle (distaster mappers Heidelberg) gave [...]
Dear colleagues, We are happy to inform you that the deadline for paper submission for almost all events at the ISPRS Geospatial Week 2015 is extended to 15 April 2015 in order to faclicitate a consistent logistics and because of several demands to extend the deadline. This applies also to our session on “Quality analysis of Volunteered [...]
Bernhard represented the GIScience discipline in the Ladenburg Discourse of the Daimler and Benz Foundation on the “Digital Model” of the UNESCO World Heritage Site Lorsch Abbey, which took place 13-14 March 2015 in Ladenburg. The Ladenburg discourse was organized by Susanne Krömker from the IWR of the Heidelberg University. The main aim of [...]
The GIScience group Heidelberg participated actively in the 2015 Annual Meeting of the DGPF (German Society for Photogrammetry, Remote Sensing and Geoinformation), which took place 16-18 March 2015 in Cologne. Bernhard hold a keynote lecture on “LiDAR Point Cloud Information and Web Infrastructure for 3D Vegetation Analysis”, which was embedded in a special Workshop [...]
This week you have the chance to visit a demonstration of our extended and specialized routing services based on OpenRouteService and the IBM Cloud solutions at the international computer fair CeBIT. Please visit our partner Heidelberg Mobil at the IBM booth | hall 2 A10 in the CeBIT “Cloud Area” from March 16. - 20. [...]
Last few months, we have been working hard on a new Web frontend for OpenRouteService.org. The new service provides all features from the old OpenRouteService (Check the advanced version from the Options page) but is much faster and also covers all of Europe, Asia, Africa and Australia! Also further new route profiles will come within [...]
Increasing traffic, especially in urban areas, leads to more and more infrastructural bottlenecks and congestion inside transportation networks. The aim is therefore to use existing transport networks as efficiently as possible. Current traffic and incident reports from the Traffic Message Channel (TMC) are an important source of information to provide further services in the context [...]
Structure and Research Focus
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).
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. Mohamed Bakillah leads the Klaus-Tschira Incubator Group on
Smart Simulation and
Dr. Hongchao Fan leads the Klaus-Tschira Incubator Group on
3D SDI and Urban Modelling.
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.
