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)!

Within wayfinding and navigation tasks, the use of landmarks has been found to be a key aspect. In particular pedestrian instructions should focus on the delivery of “landmarks” to aid in navigation. Still the use of landmarks is not common in many navigation systems. The salience of features is an important aspect of whether they [...]
The Master Thesis of Jan Kinne on the subject: “The Geographic Dispersal of the German Software Industry - Geospatial Analysis and Location Pattern Modeling” won the price “Nachwuchsförderpreis Geoinformatik 2017” of the “Runde Tisch GIS e.V.” in the category ‘Master Thesis’ with a value of 1.500 Euro. In addition Jan did also win the audience [...]
This week Prof. Alexander Zipf presented some recent work of the GIScience Research Group Heidelberg and HeiGIT at the “Münchner GI-Runde” of the “Runde Tisch GIS e.V. Munich”. The overall topic of the presentation was spatio-temporal analysis from user generated geodata such as VGI or AGI (Social Media). Examples included work on OSM quality analytics such [...]
the GIScience Heidelberg colloquium series winter semester 2016/17 finished last week with even two presentations about Modeling Tsunami based risks and exposure. We were happy to hear first an overview from Andreas Schäfer vom KIT’s CEDIM about his PhD on Developing a Global Tsunami Risk Model. Thanks for our partners in the HeiKA CrowdFDA project [...]
Recently we introduced the website OSMlanduse.org . This week it is featured as “Image of the Week” in the OSM Wiki. Thanks a lot for the recognition! It is already the second OSM Wiki image of the week from GIScience Heidelberg in this short year,as in week 4 OSMvis from our group member Franz-Benjamin was [...]
Last month GIScience Heidelberg (Prof. Zipf) participated in the First United Nations World Data Forum. This was a high level event including many organisations that generate and analyse data related to achieving the UN Sustainable Development Goals of the UN 2030 Agenda for Sustainable Development. For this we need a huge amount of data about [...]
The Special Issue on “Crowdsourced Mapping” of the international journal “Cartography and Geographic Information Science” is online. Here you can read the editorial. Further this issue includes our paper on Deriving incline values for street networks from voluntarily collected GPS traces. When producing optimal routes through an environment, considering the incline of surfaces can be of [...]
Stellenausschreibung Zur Förderung von Technologietransfer und angewandter Forschung im Bereich Geoinformatik wird derzeit mit Grundförderung der Klaus-Tschira Stiftung Heidelberg das Heidelberg Institute for Geoinformation Technology (HeiGIT) aufgebaut. Dies soll zukünftig als An-Institut weitergeführt werden. http://www.geog.uni-heidelberg.de/gis/heigit.html Hierfür wird ein Research & Innovation Manager Geoinformation Technology gesucht (100%). Die Aufgaben beinhalten insbesondere: Strategische Konzeption neuer R&D-Aktivitäten, Dienste, Anwendungen und [...]
During last weeks LandSense stakeholder at IIASA workshops various tools relevant for VGI data capture, Quality assessment and beyond were discussed. Potential hotshots for validation and improvement of OSMLanduse were FotoQuest and LacoWiki. Also discussed were platforms for hobby bird fans or for spatial data geeks. http://www.geog.uni-heidelberg.de/gis/land_sense.html http://osmlanduse.org
Last week we had a special guest for our New Years Mapathon: Nadja Schlüter, a journalist of the popular youth magazine “Jetzt” of the Süddeutsche Zeitung. Nadja had heard about the Missing Maps related activities at our institute during an interview with MSF UK and visited us to learn more about our work and disaster [...]
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.
