GIScience / Geoinformatics Research Group
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. Er war uns ein Vorbild, der immer an der Sache selbst interessiert, Humor mit kritischem und eigenständigem Denken verband und trotz seiner außerordentlichen Erfolge immer auf dem Boden blieb. Über die Klaus Tschira Stiftung förderte er seit Ende der 90er Jahre Forschung in Geoinformatik und beeinflusste diese damit auch international. In großer Trauer über seinen plötzlichen Tod und im Mitgefühl für seine Familie und Mitarbeiter danken wir Klaus Tschira und seiner Stiftung für die besondere Unterstützung. Über den so geförderten akademischen Nachwuchs wird diese noch jahrzehntelang Früchte tragen.
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
Further news can be found at giscienceblog.uni-hd.de (also as RSS-Feed). You can also follow us on Facebook and Twitter. Our publikations e.g. in Journals or Conferences can be found on dedicated pages.
The semester proceeds quickly and another talk is already approaching: We are happy to announce the next presentation in our Heidelberg University GIS colloquium which will be given by Ahmed Loai Ali from Bremen University (Cognitive Systems Research Group). Ahmed will talk about accuracy issues when classifying volunteered geographic information (VGI). See a full description [...]
In the scope of the CAP4ACCESS project, we announce a bachelor thesis (PDF, description in German) on the topic of wheelchair accessibility using the example of the Heidelberg castle gardens. The main scientific research question deals with the suitability of VGI data (e.g. OpenStreetMap, Wheelmap) for mapping the accessibility of points and ways for people [...]
Das Netzwerk GeoNet.MRN e.V. ist ein Verbund von Firmen, Verbänden, Hochschulen und Verwaltung in der Metropolregion Rhein-Neckar. Es hat sich unter anderem zum Ziel gesetzt, lokale Akteure zu vernetzen und den Wissenstransfer zu Geoinformation zwischen Praxis und Forschung zu verbessern, die Sichtbarkeit der Geoinformationsbranche zu verbessern und das Bewusstsein der Bedeutung von Geoinformation über die [...]
The disastermappers Heidelberg invite to a talk by Oliver Rack within the ‘disastermappers Heidelberg’ colloquium series at the Institute of Geography Heidelberg University. Oliver Rack is the founder of the Open Data Initiative Rhein-Neckar and will report about the situation of the Open Data Movement in the region and discuss recent projects. The presentation will [...]
A Study on the Twitter usage in the River Elbe Flood of June 2013 In recent years, social media emerged as a potential resource to improve the management of crisis situations such as disasters triggered by natural hazards. Although there is a growing research body concerned with the analysis of the usage of social media [...]
After the earthquake in Nepal just over two weeks ago, the country has been hit again by a serious earthquake. Many places have so far not received any assistance due to a lack of maps. After earlier Disaster Mapping events at the Institute of Geography at Heidelberg University and continuous activities in between, the “disastermappers Heidelberg” [...]
The lecture program of Heidelberg Geographical Society (Heidelberger Geographische Gesellschaft, HGG) begins next Tuesday, Mai 19 2015, with the Student Lecture. The students Caroline Esser, Fabian Heßlinger and Christian Berberich will report on the large field trip to Ladakh in north-western India. After the presentation the HGG invites you to the opening of the event series with [...]
The next talk in our GIScience colloquium will be given by a well-travelled researcher. Mr Alan Kwok Lun Cheung from the School of Environment, University of Auckland in New Zealand will talk about how to spatiotemporally analyse landscape structures with methods from graph theory. We are pleased to invite you to this interesting talk: Topological Analysis [...]
On the occasion of the European protest day for equal rights of people with disabilities the Heidelberg advisory board of people with disabilities organised an event at Heidelberg castle. Every year on these specific days, particular organizations plan relevant activities in order to raise awareness of the needs of disabled people including those with limited [...]
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.
