基于三维地理信息系统的城市规划技术

Urban Planning Technology Based on 3D Geographic Information System

地理信息系统(GIS)作为城市基础设施规划的核心技术,具有城市综合信息的分析、存储、交换和服务功能,可为城市的规划和决策提供强大的系统支持。城市建设需要处理日益复杂的空间关系,本文提出了专业化的三维空间决策,通过三维地理信息系统(3DGIS)建立了三维空间城市规划的技术方案和评估的流程,阐述了多种三维空间处理和分析技术、城市规划模型建立方法,以及三维信息决策支持系统。

As the core technology of urban infrastructure planning,geographic information system(GIS)has the functions of analysis,storage,exchange and service of urban comprehensive information,and can provide strong system support for urban planning and decision-making.Urban construction needs to deal with increasingly complex spatial relationships,this paper proposes professional three-dimensional spatial decision-making,establishes the technical scheme and evaluation process of three-dimensional spatial urban planning through three-dimensional geographic information system(3DGIS),and expounds a variety of three-dimensional spatial processing and analysis technologies,urban planning model establishment methods,and three-dimensional information decision support systems.
