云计算在分布式地理信息系统中的应用

地理信息系统以地图作为应用的背景,通过在地图上叠加街道,设施等具有属性的信息来提供查询,建议等服务,这样的服务现在已经变的包罗万象。云计算通过网络向用户提供使用方便而廉价的强大功能,二者的结合,使得地理信息系统的应用前景变得更加广阔。将云计算运用于分布式地理信息系统的构建中,建立了基于Google App Engine系统的分布式地理信息系统体系结构,本结构可以使用户程序的功能和效率达到最大化,也可以为海量的用户群提供更为稳定、快速、安全的服务。

Cloud Computation Applied in the Distributed Geographic Information System

The GIS takes map as its application background.It provides the service of inquiry,suggestion and so on through the adding of streets and facilities information on a map.This service has now become all-inclusive.Cloud computing network provides users with a convenient and cheap power.Combination of this two makes the application prospects of geographic information systems to become even broader.In this paper,it applies cloud computing to build distributed geographic information system and to establish a distributed GIS architecture based on Google App Engine system,which can make the applications function and efficiency of user program come to maximize,and also can provide more stable,fast and safety service for the vast amounts of user groups.
