Spatio-temporal data dynamic visualization based on temporal tree structure

This paper reviews the characteristics of spatio-temporal data and existing techniques for visualizing them, and then proposes a temporal tree structure which used to record and manipulates spatio-temporal object's predecessors and successors for the data source of dynamic visualization by algorithms of multi-temporal vector data correlation. Then, dynamic visualization methods of geometry shape and thematic were proposed with the support of temporal tree structure and case study were used to verify the methods proposed. The results and conclusion show that our method of dynamic visualization is an effective and generic way to implement dynamic modeling and visualization processes of spatio-temporal objects with various states along time.
