Abstract

The research of spatial data specification and description
mechanism is very important for spatial information sharing and collaboration,
especially for spatial information system. Most of the studies focus on the
composition of the content and implementation of specific standards, but not
aims the procedure in data integration. This study is based on the data service
architecture in spatial information system and analysis the relevant data specification
and standards. We study the resource description mechanism and metadata strategy
and summarize the relations between spatial resources description and corresponding
standards. Compared with other methods, this method can expand the spatial data
standard combined with operational features of the data in the grid. The study
gives the application in spatial information grid platform for case study, discusses
the results in detail and establishes the basis for data sharing and service
coordination.
