today Enrico Steiger successfully defended his PhD thesis about “Explorative Spatial and Temporal Human Mobility Analysis from User-Generated Data” at GIScience Heidelberg University.

The massive amount of pervasive, user-generated data creates new possibilities to discover and utilize geographic information. Tied in with this novel role of actively participating users, is a growing research challenge where the [...]

Many user-generated datasets (e.g., social media) reflect a number of different phenomena. Consequently, these datasets also comprise very different spatial scales. It goes without saying that this evokes tremendous challenges when conducting spatial statistical analyses of such datasets. When assessing spatial autocorrelation among the observations, for example, classical approaches are usually not appropriate. These were [...]

End of March and early April Prof. Alexander Zipf from GIScience Heidelberg was invited to give some lectures at the State Key Laboratory for Information Engineering in Surveying, Mapping and Remote Sensing (LIESMARS) at Wuhan University and also at the School of Surveying and Geoinformatics at Tongji University in Shanghai, China.
The presentations were about “User-generated [...]

Georeferenced user-generated datasets like those extracted from Twitter and similar social media feeds are increasingly gaining the interest of spatial analysts. Such datasets oftentimes reflect a wide array of real-world phenomena. However, each of these phenomena takes place at a certain spatial scale. Therefore, user-generated datasets are of multi-scale nature. Such datasets cannot be properly [...]

In this workshop, we want to tie two threads of research together: human computation is an important factor in both geoscience and computer vision research. In geosciences, OpenStreetMap is one of the major projects , but this is only one of numerous recent advances. In environmental sciences huge amounts of data are [...]

Last month members of the GIScience Research Group of Heidelberg University and the Doctoral College GIScience of Salzburg University met for a few days at a joint PhD Summer School on “Explorations in GIScience”. This included workshops, presentations and most importantly lively discussions on a range of topics related to research in GIScience. The set [...]

Call for Participation:
Conference “Web 2.0 und Social Media in Disaster Prevention and Flood Risk Management” Heidelberg, 17.10.2013
The summer 2013 floods which hit areas in parts of Germany and adjacent countries devastated large areas and caused a huge amount of economic losses.
Against the backdrop of this “centennial flood” this conference deals with the question how volunteers [...]
