3D Digital City Constructing Methods for People Behavior Study

Based on the concept of human-oriented geographic information, we propose a digital city constructing framework for people behavior study in this paper. Two factors, the digital human and the digital city that they live in should be considered when constructing a digital city. It´s very important to make the digital human and the digital city spatially matched; they should be aware of the behavior of each other and take responses appropriately. Around this framework, we focus our research on the methodology and key technologies to model the digital city and the digital human based on real data. We also do some preliminary explorations in the field of mutual responses between the digital city and the digital human.
