摘要：In this paper we discuss the use of volunteered geo-dynamic information (VGDI) for assessing exposure to health risks and improving analysis of associated dynamic aspects in urban settings. VGDI is introduced as an alternative and complementary data source to traditional geodata whereby both spatial and temporal aspects are highlighted. Within the FRESHER project several health-related parameters are modelled, including air pollution and access to fast food restaurant locations. We discuss how Foursquare data (and VGDI in general) can benefit integrative smart urban analytics and provide sample illustrations for a test case area in Lisbon, Portugal.
