A Web Service Based Runtime Environment for Spatial Information Grid

Spatial information grid, which is a kind of application grid for geo-computation, purchases an order for a powerful and easy-to-use running environment. In this paper, a powerful runtime environment for geo-computation is proposed based on web service. Based on it, SIG resources can be distributed, discovered, and matched, and a distributed, flexible and powerful data infrastructure is founded. Based on the implementation of the runtime environment, a SIG test bed is constructed, and the test on it shows that the runtime environment can provide a powerful, easy-to-use and robust runtime environment for SIG, and developers can develop SIG resources and SIG applications easily and quickly.
