7.07 Event Detection and Visualization of Volunteered Geographic Information


This joint project between TUM and Tongji University China aims at detecting and visualizing events, event patterns and event relationships. This project is focused on the identification of location-based semantic events in Volunteered Geographic Information (VGI). The two evolving datasets of VGI - OpenStreetMap and Geotagged Google MyMaps will be continuously monitored and they serve as potentially event-rich test data. Various geovisualization and analytical methods will be developed or elaborated. The detected event information will be then integrated with the existing geospatial data of the selected sites. The enriched data will be finally visualized in an interactive viewer.
