VGI 2018 - 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
