On Friday, our member René Westerholt held a talk at the Annual Meeting of the American Association of Geographers (AAG) in Boston. The talk which is entitled “Topological and scale-related issues in Twitter analyses through superimposed forms of spatial heterogeneity” was part of a special session on geographic data science organised by Alex Singleton from [...]

In agriculture, information about the spatial distribution of crop height is valuable for applications such as biomass and yield estimation, or increasing field work efficiency in terms of fertilizing, applying pesticides, irrigation, etc. Established methods for capturing crop height often comprise restrictions in terms of cost and time efficiency, flexibility, and temporal and spatial resolution [...]
Next Wednesday, René Westerholt will talk about the spatial analysis of Twitter data. The talk is part of the “WISC Seminar Series,” which is hosted by the Warwick Institute for the Science of Cities at University of Warwick, Coventry, UK. The talk starts by highlighting the types of spatial analyses that have been conducted so [...]

The results of a study dealing with photogrammetric 3D geodata of mass wasting sites conducted at the GIScience were considered to be worth publishing in the Journal of Applied Remote Sensing: ‘Terrestrial and unmanned aerial system imagery for deriving photogrammetric three-dimensional point clouds and volume models of mass wasting sites.‘
Three-dimensional (3D) geodata of mass wasting [...]
Enrico Steiger defends PhD on Explorative Spatial & Temporal Human Mobility Analysis from User-Generated Data
Posted in Crowd Analyser on Feb 5th, 2016
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 [...]
