Dynamic Cartographic Representation of Spatio - Temporal Data

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 important to associate the spatio-temporal process with a vivid representation. The paper propose a way for visualization base on dynamic symbol base, by which represent the spatio-temporal process in a more vivid and visually way. The authors propose a new classification of spatio-temporal change pattern, which builds a fundamental basis for the representation of dynamic phenomena. Dynamic visual variable of dynamic symbol for the display of changing spatialtemporal objectives will be discussed, a framework will be designed and implemented for the dynamic visualization. * 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.
