  • Enrico Steiger defends PhD on Explorative Spatial & Temporal Human Mobility Analysis from User-Generated Data

    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…

  • Statistical investigation of geo-tagged shipping information

    Inspection and analysis of geo-tagged shipping information could provide insights to the transformation of a variety of “global spaces” during times of rapid globalization. One of the famous resources of shipping data is a shipping newspaper called LLOYDS lists. The list contains weekly and later daily information on global shipping since the late seventeenth century…

  • Modeling the evolution of OpenStreetMap with Cellular Automata using a new VGI Contribution Index

    Major research efforts have so far dealt with OSM data quality analysis, but the modality of the evolution of OpenStreetMap (OSM) across space and time has been barely noted. Therefore, a new study by Jokar Arsanjani et al. that has recently been accepted for publication in Transactions in GIS aims to analyze spatio-temporal patterns of…

  • Mapping collective human activity based on mobile phone data

    Identifying and characterizing variations of human activity – specifically changes in intensity and similarity – in urban environments provide insights into the social component of those eminently complex systems. Using large volumes of user-generated mobile phone data, we derive mobile communication profiles that we use as a proxy for the collective human activity. In this…
