摘要
地理信息服务的多源、异构和分布式特征是制约地理信息共享的关键问题。研究了一种多源、分布式和异构地理信息服务的智能化无缝聚合方法,提出了一种混合服务聚合模式,实现了按网络环境、数据范围、位置和优先级等条件对符合OGC标准或WSDL/WADL描述的各种数据服务、处理服务等分布式、异构地理信息服务的智能调度和动态组合。在安吉美丽乡村地理信息服务平台中,通过对本地与天地图和百度等服务资源的聚合应用,验证了本文方法的有效性。
Multi-source,heterogeneity and distributed feature are the key issues for geographic information sharing. This paper devotes an intelligent seamless aggregation method and proposes a hybrid service aggregation model which achieves intelligent scheduling and dynamic combination of the distributed and heterogeneous geographic information based on OGC and WSDL/WADL under the conditions of network environment,data range,location,priority level,etc.Anji Beautiful Countryside Geographic Information Service Platform can demonstrate the validity of this method in the aggregation of the local service,Map World and Baidu.
