基于云计算的WebGIS分析构架研究

云计算作为以互联网为中心的一种新兴商业计算模式,也是当前重要的技术热点。 WebGIS是一种利用Internet/Intranet技术,采用HTTP,在Internet/Intranet环境下实现对分布式地理信息的分布式获取、分布式存储、分布式处理、分布式分析、分布式查询、显示和输出的地理信息系统。通过分析云计算、WebGIS的特点,云计算的模型框架以及WebGIS 系统的层次结构,提出将云计算和WebGIS相结合,建立基于云计算的WebGIS构架。对实现海量空间数据存储、空间分析和空间信息检索提供实时地理信息服务,提高了系统的稳定性和效率。

Research on WebGIS Analysis Framework Based on Cloud Computing

Cloud computing as a new business to the Internet as the center of the computing model,also is the important technical hot. WebGIS is a geographic information system using Internet/Intranet technology,applying HTTP,realizing distributed acquisition,distribu-ted storage,distributed processing,distributed analysis,distributed query,display and output of distributed geographic information in Inter-net/Intranet. Through the analysis of the characteristics of cloud computing and WebGIS,cloud computing model architecture,and Web-GIS hierarchy,combined the cloud computing and WebGIS,establish the framework of the WebGIS based on cloud computing. For the realization of magnanimous spatial data storage,spatial analysis and spatial information retrieval provide real-time geographic information services,improving the system stability and efficiency.
