The context for geographic research has shifted from a data-scarce to a data-rich environment, in which the most fundamental changes are not the volume of data, but the variety and the velocity at which we can capture georeferenced data. A data-driven geography may be emerging in response to the wealth of georeferenced data flowing from sensors and people in the environment. Some of the issues raised by data-driven geography have in fact been longstanding issues in geographic research, namely, large data volumes, dealing with populations and messy data, and tensions between idiographic versus nomothetic knowledge. There is potential to use Big Data methods (i.e. geocomputation, visual analytics) to inform both geographic knowledge-discovery and spatial modeling.
As part of the AAG 2018 Symposium on CyberGIS and Spatial Data Science, this session aims to capture the latest efforts on the development in data-driven geography including but not limited to theories and approaches in data-driven geography, novel applications in various domains such as precision agriculture, human dynamics, and public health, and current challenges and future opportunities in data-driven geography.
