Abstract

Geographic space is typically conceptualized either as discrete objects or as continuous fields. Considerable efforts have been carried out for the representation and management of the spatial data, based on the object view of space. However, field-based data models are less developed in GIS, especially when it comes to the modeling and representation of their spatial dynamics and behaviors. The limitations of GIS are mostly related to the 2D and static nature of their spatial data structures. In this paper, we explore the potentials of Voronoi diagram as an alternative spatial data structure that can allow more realistic representation of geographic dynamics, especially of dynamic fields and processes in 2D and 3D spaces. The paper presents a review on how different types of Voronoi diagrams for points, line segments and polygons could be effectively used to represent and simulate the geographic dynamics in different contexts.
