摘　　要：社会的发展对网络地图集成提出了更高的要求,技术的进步使得这种要求成为可能。现有的地图集成模式主要有两种。地图服务商提出的集成模式,依赖于自己提供的数据源,且对开放标准的支持较弱;开源社区提出的基于WMS的集成模式,虽然实现了数据源的独立,但过于专业而不适合普通用户使用。为了更好地满足地图集成的要求,本文提出一种屏蔽领域细节的轻量级开放地图服务集成模式,它支持标准的网络地图服务,同时又屏蔽领域细节,不要求使用者具有专业知识,具有良好的适用性。本文实现的原型系统,初步验证了这种模式的可行性。There are two types of map integration models currently. The type developed by commercial map providers does not support independent data sources and it is generally weak on supporting open specifications. Another type is proposed by some open source communities such as quickWMS and OpenLayers. It supports independent data sources by integrating open WMSs but is not suitable to general users because it requires too much professional knowledge. To simplify and improve the operation of integrating map services, this paper proposes a lightweight domain knowledge-hidden model of integrating open map services. This model supports open WMS while hides details of domain knowledge and specifications. This model lets non-professional users to integrate open map services and publish thematic information upon this integrated map services. A prototype system is designed and implemented, which demonstrates the feasibility of this model.
