基于Cesium的三维电网WebGIS开发与实现
|
摘要
近几年来开源项目在全世界发展迅速,GIS领域的软件也日趋开源化。开源GIS软件在国家电网中的应用还很少,近几年我国正在大力发展智能电网,将开源GIS软件应用于国家电网无疑是为电网GIS的发展开辟了新的研究方向。本文研究了基于Cesium开源的三维WebGIS系统的开发与实现。通过对WebGIS系统结构、实现模式、空间数据库管理模式以及一系列的开源项目与技术,如Tomcat、Geo Server、PostgreSQL、OpenLayers、Cesium等的深入学习与研究,提出了采用这一系列开源技术进行WebGIS的系统开发模式,实现了GIS的基本功能,并完成了大数据平台的计算模型与数据挖掘结果三维展示的任务。
With the open-source projects in the world being promoted,GIS software also began to open up the era of open-source.Open-source GIS software in the national grid application is not too much,and China is vigorously developing smart grid in recent years,open-source GIS software applied to the national grid is undoubtedly for the development of power grid GIS has opened up a new research direction. This paper studies the development and implementation of open-source 3 D WebGIS system based on Cesium.In-depth researching and studying the WebGIS system architecture,implementation model,spatial database management mode and a series of open-source projects and technologies such as Tomcat,Geo Server,PostgreSQL,Open Layers,Cesium and other,this paper proposes the use of this series of open-source technology for the development of WebGIS,which achieves the basic functions of GIS,and completes the task of the three-dimensional display of computational model and data mining results of the Power Big Data Platform.
