GIScience / Geoinformatics Research Group
Essential parts of the research focus of the GIScience research group (Geoinformatics) are reflected by the PhD graduate school (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 big 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. Some realized services can be discovered online, e.g. OpenRouteService.org or uni-heidelberg.de/openmapsurfer.
The Klaus Tschira Foundation supports establishing the "Heidelberg Institute for Geoinformation Technology" (HeiGIT) at the Institute of Geography at Heidelberg University. The aim is to improve knowledge and technology transfer from fundamental research into practice within the field of Geoinformatics. The focus areas comprise ("Big Spatial Data Analytics"), "Navigation Intelligence and Location Based Services" and "VGI for Humanitarian Aid in Disaster Management".
We offerJobs (esp. for PostDocs)!

Last week, the German FOSSGIS conference about Free and Open Source GIS software was held in Passau. GIScience was also there with a small delegation, presenting some of our current research topics, from routing, to data analysis and machine learning. The talks (in German language) are already available on youtube, for example: Routenplanung durch Flächen (by [...]
Last week saw the Workshop on Crowd Assisted Sensing, Pervasive Systems and Communications (CASPer 2017) at the 15th IEEE International Conference on Pervasive Computing and Communications. Here you find some impressions from the event. Alexander Zipf participated as invited panelist at the panel session of CASPer 2017. The panel discusses processing unstructured Big Data and [...]
On Saturday, 18.03.2017, the Neuenheimer Feld of the University Heidelberg was the area of interest for children participating in the GIScience KinderUni workshop at the Institute of Geography “MapSwipe und uMap – Mach‘ mit beim Mappen an PC, Tablet und Smartphone”. After an introduction about Geography and Geodata in general, they could do some mapping [...]
Geographic information crowdsourcing is an increasingly popular approach to derive geographic data about human settlements from remotely sensed imagery. However, crowdsourcing approaches are frequently associated with uncertainty about the quality of the information produced. Although previous studies have found acceptable quality of crowdsourced information in some application domains, there is still lack of research about [...]
This week you still have the chance to meet colleagues from HeiGIT team at CeBIT 2017 in Hannover. We present Smart GeoServices for Smart Cities in Halle 7 at the Smart City Forum booth together with our colleagues from heidelberg mobil.
in case you are this week not at CeBIT in the north of Germany, but rather at FOSSGIS in the south, you have the chance meet us also there and listen to several presentations on OSM work at HeiGIT and GIScience HD by our team member Martin Raifer. The main talk will be on OSM-History-Analysis based [...]
Several urban studies have been increasingly relying on spatial data provided by Volunteered Geographic Information (VGI) sources. The matching of features across different VGI projects may serve to assess and improve the reliability and completeness of VGI data. In a recent study, we first provide a short discussion on the similarity measures often used for [...]
How can we combine technology and digitalisation with doing good? That is the main focus for the 2017 Impact Night series organized by and at the Impact Hub Bergen. Last evenings Impact Night was about Tech for Change and disaster response. Therefore the Impact Hub team invited Per Aarvik, President of the StandbyTaskForce, Sam [...]
VGI-Analytics offers two formats for paper submission: Workshop Short Paper (2000 to 3000-word manuscript) New Submission Deadline 28th March 2017. Authors are requested to follow the formatting guidelines for short paper submissions on the AGILE 2017 call for papers page and use the Word .doc template or the Word .docx template provided. Short papers should be submitted directly via [...]
The set of interactive visualizations “OSMvis” from our GIScience HD team member Franz-Benjamin are now online at: http://osm-vis.geog.uni-heidelberg.de. Nice work Franz-Benjamin! OSMvis is a collection of visualizations related to OpenStreetMap (OSM), in particular the OSM database, the OSM wiki, and the use of OSM data in general. OSMvis aims at exploring the generation, modification, and use of OSM [...]
We have moved. Our address has changed.
The phone numbers of some of our colleagues have also changed.
Structure and Research Focus
In addition to investigating VGI, Big Spatial Data Analytics, LBS for Mobility and also Disaster Management in the whole group, in particular the LiDAR research group led by Bernhard Höfle 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 or solar potential assessment for buildings).
In Memoriam Klaus Tschira
Am 31. März 2015 verstarb unerwartet und viel zu früh Herr Dr. h.c. Dr.-Ing. E.h. Klaus Tschira. Wir trauern um einen großen Förderer der Wissenschaft.
