City Planning Spatial Decision Platform Based on GIS
-
摘要: 城市规划管理工作越来越复杂, 利用GIS和数据库技术建立空间辅助决策平台来处理规划管理业务显得尤为迫切。介绍了空间决策支持系统(spatial decision support system, SDSS), SDSS是通过空间数据引擎(spatial data engine, SDE) 建立与商用数据库的关系与存储, 其结果体现利用了GIS的VRML和3D技术, 设计出城市规划空间辅助决策软件平台的体系结构和应用模型.文章提出了决策平台核心内容在于建立成熟完备的决策模型库和决策算子的实现过程, 以及计算结果的多样化表达.通过决策软件平台的建立能够为城市规划管理决策提供客观准确的理论依据, 为决策者科学决策奠定基础.Abstract: City planning management has become highly complex in recent years. GIS and database technology provide a means of improving city management systems. One method of managing the present condition and characteristics of city planning is through a spatial decision-making platform. The paper explains SDSS is spatial decision support system, and describes the SDSS data is stored in the database and connected throuth the spatial data engine (SDE). In GIS and express the result using VRML or 3D technology, and discusses the design of the spatial decision-making software platform's system structure and application model. The kernel of the platform is to build the perfect decision-model database and decision operator, expressing all kinds of the calculable results. Such a platform would provide the basis of accurate, systematic decisions by collating many strands of information for presentation to the decision maker.
