领域本体网格化城市地理信息共享模型

城市空间基础信息平台中的空间信息服务存在语义不一致、服务集成困难等问题,使得平台的空间信息共享出现瓶颈。针对这一问题,本文提出一种基于领域本体的网格化城市信息共享模型,在平台技术架构之上,建立具有本体语义的空间信息网格,从面向具体应用的角度描述空间信息服务,消除平台空间信息服务之间语义的不一致,网格化管理平台的空间数据与软件服务资源。实验表明,该模型有助于更好地实现平台的地理信息服务与共享。

A model for city geographic information sharing based on domain-ontology grid

The geo-information services in the platform for city spatial basic information was hindered due to the problems such as the inconsistency in spatial semantics of information data,difficulties in the integration of spatial information service.To solve these problems,a model for spatial information sharing based on spatial information semantic grid(SISG)was generated in the paper.In the SISG,spatial information services were described from domain application.With the help of SISG,the inconsistency in the spatial information across the services was eliminated and the resources like spatial data,geo-information services could be managed better.Experiments approved that this model could enhance the geo-information service and sharing.
