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)!

In our recently published study “Direct local building inundation depth determination in 3-D point clouds from user-generated flood images” we present a new approach for deriving local building inundation depth from ordinary user-generated flood images captured during a flood event. After reconstructing a 3-D scene of the building of interest with close-range photogrammetry (CRP) algorithms, [...]
A recently published paper (Rousell & Zipf 2017) presents a prototype navigation service extending OpenRouteService (Schmitz et al. 2008) that extracts landmarks suitable for pedestrian navigation instructions from the OSM dataset based on several metrics. In general, when providing instructions on how to get somewhere, people generally include landmarks in their instructions - “Turn left [...]
Already one year ago that MapSwipe was officially launched! A big thank you to our contributors for your support - one year of tapping, swiping and putting families on the map! In just one year thousands of users contributed more than 10 million taps and thereby provided crucial information on unmapped places. In projects like shown below settlement [...]
Yesterday, our colleague Dr. Martin Hämmerle defended his PhD thesis with great success. We would like to congratulate him - with our sincere thanks for his hard work and amazing research the last years. Martin is an expert on 3D geodata (with focus on 3D point clouds from LiDAR and photogrammetry), methods for 3D processing and [...]
To take bathymetric measurements in areas with shallow water is very challenging for methods such as SONAR or bathymetric LiDAR. In our study “Assessing the Potential of a Low-Cost 3-D Sensor in Shallow-Water Bathymetry”, we examine the performance of a low-cost 3D camera when capturing bathymetry in waters up to 0.4 m depth. The tested measurement [...]
Noise pollution is a growing problem in many urban environments, affecting citizens’ daily life. It can reduce citizens’ happiness, increase their stress, and even people them get sick if they are exposed to noise pollution for a long period of time. In recent studies we investigate the use of crowdsourced data to derive noise polluted [...]
Open Position: Software Engineer Geoinformation Technology / OpenStreetMap Heidelberg Institute for Geoinformation Technology (HeiGIT) In order to promote technology transfer and applied research in the area of Geoinformatics, the Heidelberg Institute for Geoinformation Technology (HeiGIT) is currently being established with the support of the Klaus-Tschira Foundation. http://www.heigit.org. This is to be continued in the future as an [...]
we cordially invite everybody interested to our next open GIScience colloquium talk “Heatmapping”: Accessing Geodatabases of Building Stocks for the Development of Spatial Energy System Models Sebastian Blömer ifeu Institut für Energie- und Umweltforschung Heidelberg Time and date: Mon, July 10, 2.15 pm Venue: INF 348, Room 015, Department of Geography, Heidelberg University To evaluate the technological and economic feasibility of the [...]
Research in psychology and public health shows that there are environmental factors that cause an area to impose more or less stress to a person. One example is that being surrounded by natural green areas (meadows, parks, trees and forests etc. or also blue water areas) has a relaxing influence to the mood of a [...]
Recently Barrons studied the effect of Amazon.com buying Whole Foods for US$13.7 billion. They used the OpenRouteService Isochrones API for an detailed accessibility analysis of the whole US. With OpenStreetMap based OpenRouteService and US Census data they calculated how much US population is covered within different driving times from the US wide network of the 444 Whole [...]

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
