BSTRACT
The spatio-temporal visualization and analysis techniques play
important roles in geographic information systems and knowledge
discovery. In this research, we introduce three spatio-temporal analytical
techniques including spatio-temporal visualization, space-time kernel
density estimation, and spatio-temporal autocorrelation-analysis for
exploring human mobility and urban structure patterns. These spatio-
temporal analytics can help to answer questions like: Where are the
spatio-temporal hotspots of human activities? How to explore spatio-
temporal patterns in three-dimension GIS? Experiments are conducted
using a large scale of phone-call detailed records in urban space.
Expeditions on the spatio-temporal functionality and techniques
contribute to the GIScience community for the future development of
Space-Time GIS; and more broadly, it has potential to be applied in other
disciplines, e.g., environmental, urban and social sciences.
