丽水市违章建筑管理GIS系统建设

Construction of GIS System for Illegal Building Management in Lishui City

无人机倾斜摄影的高分辨率影像数据生成的三维影像数据具有直观、逼真、可量测的特点。针对目前屋顶建筑违章数据难采集、精度低的问题,提出使用三维影像数据结合数字测图软件生产违章建筑数据,生产周期短、现势性强。使用PostgreSQL数据库和ESRI的ArcSDE空间数据库引擎管理违章数据,调用测绘部门的房屋分层分户数据服务、各时期影像数据等,构建丽水市违章建筑管理GIS系统,实现违章建筑数据的有效管理和可持续更新,为城市管理提供数据支撑和决策依据。

The 3D image data generated by the high-resolution image data collected by the drone oblique photogrammetry is intuitive,realistic,and measurable.In view of the problems of difficulty and low accuracy in the illegal data collection of roof buildings,it is proposed to use three-dimensional image data combined with digital mapping software to produce illegal building data with short production cycle and strong current situation.It uses PostgreSQL database and ESRI′s ArcSDE spatial database engine to manage violation data,the stratified household data service of the surveying and mapping department,and image data of each period to construct the GIS system of illegal building management in Lishui city to realize effective management of illegal building data and sustainable updating,which provides data support and decision-making basis for urban management.
