摘要
结合当前的网格技术,借鉴OGSA（Open Grid Services Architecture）体系结构,给出了一个基于网格技术的WebGIS体系结构模型,该模型包括资源层、网格中间件、服务层和应用层,详细论述了四层的结构和功能,并对GML共享技术、网格中间件和网格服务等关键技术进行了分析。实现了分布异构环境下不同格式空间信息的互操作,有利于WebGIS产品的多元化集成。
Based on the idea of grid, this paper developed a new architecture WebGIS system model, which combined with current grid computing technology and used OGSA（Open Grid Services Architecture） for reference. This model includes the resource layer, the middleware layer, the service layer and the application layer, and the function and the structure of each layer was detailed dissertated respectively. The analysis was made on the key technology of GML Share technique, the middleware layer and grid service. The interoperation of spatial information with different formats in distributing and heterogeneous environments is implemented, and the WebGIS products can benefit from it in multiplication integrated.
