摘要
空间数据互操作是空间信息网格(SIG)的关键技术之一,文中提出了一种较为通用的SIG数据互操作方法.该方法基于OGSA-DAI扩展了一个空间数据访问活动,设计了一套空间数据访问接口,从而以空间数据网格服务的形式实现对分布、异构的多维空间数据的互操作,是基于Web服务的空间数据互操作方法的一种具体实现,实验系统以二/三维空间数据为例验证了其可行性.
Geospatial data interoperability is one of key technologies of Based on OGSA-DAI, a common method of geospatial data interope Spatial Information Grid (SIG). rability is proposed for SIG. The method extends OGSA-DAI technology to interoperate distributed, heterogeneous, and multi dimensional geospatial data on the SIG through the same geospatial data grid services, by adding a geospatial data access activities and designing a set of geospatial data access APIs. The method is an implementation of the geospatial data interoperability method based on Web Services. Finally, the proto-type system reveals a good feasibility of the method for 2D/3D geospatial data interoperability.
