应急管理信息化矢量瓦片技术研究

Research on emergency information vector tile technology

针对目前栅格瓦片技术无法满足浏览器大量地理数据交互以及空间分析的问题,本文引入矢量瓦片技术概念,从矢量瓦片快速发布、矢量瓦片渲染、地理数据在线交互等多个角度研究了矢量瓦片技术在应急管理信息化系统中的应用原理和动态渲染效果,以保障应急业务系统满足应急资源数据的快速发布、高效浏览、资源数据在线编辑、交互式查询和在线分析等应用需求。在基础地理信息赋能应急方面,该技术可提升应急管理部门在应急管理、安全生产、防灾减灾等方面的应急管理能力。

The vector tile technology is introduced in this paper to solve the problems that the current grid tile technology can’t meet a large number of geographic data interaction and spatial analysis of browsers.The application principle and effect of vector tile technology in emergency management information system are studied from the perspectives of rapid release of vector tiles,rendering of vector tiles and online inter⁃action of geographic data,so as to ensure the application requirements of the emergency system for rapid release,efficient browsing,online editing,interactive querying and online analysis of emergency resource data.In terms of enabling intelligent emergency response with basic geographic information,it can improve the emergency management capability of emergency management departments in the fields of emergency management,safe production,disaster prevention and reduction.
