Analysis on Geographical Changes and Research on Spatio- Temporal Patterns

As efforts grow to develop spatio-temporal database systems and temporal geographic information systems that are capable of conveying how geographic phenomena change, it is urgent to analyze the impetus and mechanism that the spatio-temporal process happed. The authors proposed a set of universal change patterns for modelling of spatio-temporal processes, which builds a fundamental basis for the representation of dynamic phenomena. Change detection algorithms were also developed and pattern association methods were implemented for the modelling of changing geographical world. * Yang Ping, PhD Candidate in Cartography and Geographic Information Engineering of Wuhan Uni, Research interests includs: Spatio-temporal visualization, Geophysical dynamic visualization and Temporal GIS.
