New missions, technology and partnerships – Users navigate the system without needing to know how/who is providing each service. – DAAC web sites and services still exist, but use the same high-level navigation, nomenclature and other functionalities so users are familiar when they arrive. More than just a website or portal – An active and immersive user experience leveraging existing and future Web Services (e.g. W*S, SOAP, RESTful) into a seamless package – search, subset, visualize and deliver data in one session with one username and password while invoking multiple remotely hosted tools – Cloud capable Fresh and continually updated and coordinated content Goals EOSDIS WEB SITE ECHO file search ECHO file search GCMD keyword search GCMD keyword search User Reg Outreach EMS VizTool(s) Rapid Response Utilize EOSDIS-Wide Services Reuse/Repurpose/Integrate Content ESDSWG ESDIS SIPS DAACs maintain web sites but implement CMS so they can feed content to ESDS site DAACs maintain web sites but implement CMS so they can feed content to ESDS site DAAC Community LANCE Directed Infusion ACCESS Infusion ACCESS Infusion Others Invoke DAAC Specific Services Subsetter DAAC KML OPeNDAP GeoRSS Web Services OGC W*S Application Server Middleware Content Management System NASA HQ Site External Sites Earth Observer, Climate, USGS, NOAA...
