The Design of Registry Service for Remote Sensing Data Processing Software Based on Grid Computing

Grid computing can create a computing environment handling PetaBytes of distributed data, tens of thousands of heterogeneous computing resources and thousands of simultaneous users from many research institutions. Developing new remote sensing data processing software based on grid computing (RSDPS-G) has been a trend. The registry service is an essential component in RSDPS-G for sharing and interoperating huge volume distributed remote sensing data, as well as publishing and querying services. The registry service is also a key component for workflow-based virtual remote sensing data products. We propose to build a registry service based on monitoring & discovery system (MDS4) which is a module of globus toolkit (GT4). It can be integrated seamlessly with the services in GT4 and make it easy for geospatial Web services/remote sensing data and services registered into the grid.
