VGI Geovisual Analytics Workshop

VGI Geovisual Analytics Workshop

In the past years Volunteered Geographic Information (VGI) has emerged as a novel form of user-generated content, which involves active generation of geo-data for example in citizen science projects as well as the passive collection of data via the user’s location-enabled mobile devices. The interpretation, visualisation and usage of such multi-source data is challenging because of the large heterogeneity, the differences in quality, the high update frequencies, the varying spatial-temporal resolution, subjective characteristics and low semantic structuring. The Geovisual Analytics Workshop will investigate how the general concepts of Visual Analytics can be used for the spatio-temporal analysis and interpretation of VGI.

Potential submission topics include, but are not limited to:

  • Efficient representation and modelling of geospatial big data
  • Quality assessment and uncertainty visualisation of VGI
  • Scalability and Multi-scale views of VGI/social media data
  • Real-time visualisation and spatio-temporal analysis of data streams
  • Visual exploration of Location-Based Social Networks data
  • Analysis and visualisation of spatial–temporal trajectory data
  • Joint analysis of VGI/social media data originating from different data sources
  • Location privacy issues in Geovisual Analytics
