基于数码城市GIS的日照分析系统的设计与实现*

针对传统的基于CAD平台的日照分析系统不能适应城市规划与管理快速发展的需求，提出了将城市规划中的各种信息在统一的数据库平台上进行组织与管理，以数码城市GIS及其他技术为核心，并在此基础上整合日照分析的应用专题及其他应用专题的思路。特别对涉及到的关键技术包括三维数据模型的设计、基于Oracle的数据库管理、CAD数据的嵌入与操作、日照分析技术、组件式GIS技术等进行了详细的介绍。最后对基于数码城市GIS软件CCGIS日照分析系统CCSunAnalysis的实现与应用作了简要介绍。

Design and Implementation of Sunlight Analysis System Based on CyberCity GIS

Aiming at the lack of traditional sunlight analysis system based on CAD system for processing urban plan and management,this paper presents an idea that based on CyberCity GIS and other techniques,all kinds of urban planning information are organized and managed on unite database platform and many application subjects of urban planning are integrated. Some relative key techniques including the design of 3D data model,database management based on Oracle,the fusion between CAD data and GIS data,sunlight analysis,ComGIS and so on are emphasized.And the implementation and application of a sunlight analysis system:CCSunAnalysis based CyberCity GIS software CCGIS is described briefly.
