Projects > EIE


Earth Information Exchange is a joint effort among the NASA, Earth Science Informaiton Partnership (ESIP), and George Mason University (GMU). The objective of the Exchange is to share information at the levels of metadata, data, services, and knowledge. As a Spatial Web Portal, the Exchange utilizes Liferay Portal as portal container and the Liferay Portal provides over 60 portlets for generic and fundamental functional support. On the other hand, to make the Exchange support a specific domain requirement, such as the one from the Earth science communities, additional portlets, scuh as WMS Viewer and Semantic Search, have been developed to support the Exchange objective. Because all the portlets developed are compliant with Java Servlet Request (JSR)268 specification, the portlets can be easily deployed and integrated into other portals , such as Earth Science Gateway, in an interoperable fashion.
