摘要:Simulation of a dynamic and continuous phenomenon (field) is a difficult task for GISs as their data structures are 2D and static and are not well-adapted to manage neither the dynamic behavior of the phenomenon nor its geometrical and topological information. In this paper we present the Voronoi diagram as an alternative data structure that, through its useful geometrical and topological properties, provides an adequate discretization of a field and can represent its temporal changes by providing numerical integration methods on either dynamic or kinetic mesh
