针对当前网络地理信息系统(WebGIS)中存在的效率问题和服务器端压力过大的问题,提出了基于FastCGI的多进程、分布式集群的WebGIS构建方案。详细介绍了该方案中服务器端地图服务器的体系结构、功能模块、工作流程以及集群部署实现。在此基础上实现了符合OGC标准规范的基于FastCGI分布式集群Web-GIS平台,并进行了性能测试,同时在实际项目中对该方案进行了验证。结果表明,相比于当前其他模式的Web-GIS,基于FastCGI多进程、分布式集群构建的WebGIS具有效率更高、可扩展性更强、稳定性更好的特点。 更多还原

【Abstract】 Due to the problem of efficiency and huge load of server in current common WebGIS,this paper proposed a method to build WebGIS based on FastCGI by the model of multi-process and distributed cluster.This paper introduced the architecture,functional modules,working flow,and realization of distributed cluster of the map server of WebGIS based on FastCGI.By these theories,built a WebGIS which implemented the OGC specification.The result shows that a WebGIS based on FastCGI by multi-process and distr... 更多还原
