WebGIS架构下的地理信息系统构建研究

摘要

针对目前地理信息系统对地理位置不能实时掌握,缺乏自组网管理等方面的问题,采用WebGIS技术构建物联网环境下的地理信息管理系统;利用OpenStack云计算平台建立信息传感网.采用Web技术进行地理信息系统GIS的网络组网设计,实现了对地理信息的对象存储、虚拟计算服务以及远程调用和监控等操作;在系统测试中通过对地理位置定位模拟,验证该系统的有效性,测试结果表明,采用该系统进行地理信息管理,对地理位置的定位精度较高,能使各类地理信息动态显示在界面上,系统的稳定性较好.%At present,the geographic information system of geographical location cannot be real time control,lack of network management and other issues,a geographic information system construction of IOT environment using WebGIS technology,the establishment of information computing sensor network platform using OpenStack cloud network,design of geographic information system GIS using Web technology,the realization of geographic information object storage,virtual computing and remote service invocation and monitoring operation.Through the simulaion of the location in the system test,verify the validity of the system,the test results show that the geographical information management in the system,high positioning accuracy of the location,can make all kinds of geographic information dynamic display in the interface,the system is stable.
