Overview • Introduction • Architecture • Key technologies • Functionalities • Characteristics and future development • References
Problems in Earth Science Data Sharing and Accessing • Large amount of data • Poorly catalogued • Widely dispersed
So, what do we need? • For Users: Fast access and acquisition of Earth Science Data • For Professionals: Data integration and sharing Applications integration and sharing Efficient spatial data management • For Decision Makers: Models and accurate Predictions for future decision making. How to achieve this?
Earth Information Exchange--EIE • A joint effort among the NASA, ESIP, and GMU. • Standards-based, web-services enabled Spatial Web Portal. • Sharing data, products, services and knowledge.
Objectives • Reuse developed components with minimum effort. • Reduce cost and extend return. • Leverage and sharing current resources • NASA ESG, ESIP EIE, GMU Computing, UAH NOESIS, Rob’s SWEET, etc.
