摘要
为满足三维立体空间的规划管理和空间治理需求,利用 WebGIS、GeoServer、Cesium、Post-greSQL等技术,设计了国土空间规划数据库,开发了三维规划辅助系统.该系统形成了涵盖基础功能、信息查询、辅助分析、辅助设计、辅助审查的框架体系,其中基础功能包括飞行漫游、量测、图层管理、分屏、卷帘等,信息查询包括兴趣点查询、属性查询、楼层分层分户查询等,辅助分析包括通视分析、可视域分析、日照分析、挖填方分析和裁切分析等,辅助设计包括天际线分析、生成控规盒子、控高分析、贴线率分析和宽高比分析等,辅助审查包括设计方案加载、符合性判断、对比和提交意见等.该系统实现了国土空间规划编制流程中的三维辅助分析,实现了国土空间规划审查流程中的三维审查及意见留痕,提升了国土空间规划编制和审查水平.
Abstract
To meet the needs of planning,management,and spatial governance in three-dimensional space,a spa-tial planning database was designed and a three-dimensional planning assistant system was developed,using tech-nologies such as WebGIS,GeoServer,Cesium,and PostgreSQL.The system has formed a framework system that covers basic functions,information inquiry,auxiliary analysis,auxiliary design,and auxiliary review.Basic func-tions include flight roaming,measurement,layer management,split screen,rolling shutter,etc.Information inquiry includes interest point inquiry,attribute inquiry,floor layering and household inquiry.Auxiliary analysis includes visibility analysis,display area analysis,sunlight analysis,excavation and filling analysis,and cutting analysis.Auxiliary design includes skyline analysis,generation of control gauge boxes,height control analysis,line sticking rate analysis,and aspect ratio analysis.Auxiliary review includes design scheme loading,compliance judgment,comparison,and submission of opinions.It can achieve three-dimensional auxiliary analysis in the process of spa-tial planning formulation,achieve three-dimensional review and opinion retention in the process of spatial plan-ning review,and improve the level of spatial planning formulation and review.
