Simulation of self-organizing urban systems based on object-oriented GIS

摘要

The object-oriented GIS data model enables the specification of applications not only to be a more accurate representation but also to incorporate "intelligent" objects into an analytical framework through their associated behaviors and methods. In this paper, a specific logical data model incorporating the decision-making support techniques is designed in the object-oriented approach, in order to restructure the NEG basic models for this research case to support the empirical explorations of self-organizing urban systems of Eastern China; furthermore, this logical model is directly mapped into the ArcGIS geodatabase data model within the framework of relational database technology. A prototype GIS software system for simulating urban hierarychy of study case in the environment of object-oriented GIS is proposed.
