Specification and Applications of Online Sharing Interface for Geospatial information

In order to support the sharing and interoperability of multi-source and heterogeneous geospatial data in the wen environment, the use of standardized interface is an effective means. This paper analyzes the differences of geospatial data from multiple levels such as data source, metadata model and data interface. The NOAA CLASS data and NASA ECHO data system are adopted to demonstrate the usage of geospatial online sharing. Combined with the current relevant standards of ISO and OGC, this paper puts forward the solution of online sharing from the perspective of standards, and gives an application demonstration in combination with the needs of agricultural applications.
