MCS-based Spatial Metadata Catalog Service
Zhang Guo · Jisuanji gongcheng · 2008
It is difficult for MCS to manage distributed multi-source spatial data.This paper introduces a new Spatial Metadata Catalog Services(SMCS).The spatial relation aggregation operations and catalog interfaces are defined.Thematic classical and nested aggregated collection referred to spatial relations are taken as governable method in the hierarchical catalog.And catalog index is created to find and locate distributed components which are efficiently proved to access,manage huge spatial data.The new application way enabled with SMCS can support efficiently run-time integration and share for huge multi-source spatial data under grid environment.
