Abstract :
The Earth Observing Systems (EOS) Data Gateway (EDG) is the extension of Version O Information Management System (IMS) developed for the EOS Data and Information System (EOSDIS), a NASA-sponsored open, distributed information system. EOSDIS manages the data and information from a variety of pre-EOS and EOS-era Earth observation satellites, as well as data from related Earth science field measurement programs. The goal of the EDG is to provide seamless access to distributed archives at NASA EOSDIS Distributed Active Achieve Centers (DAACs), affiliated data centers, and international data centers in a single online session. There are currently over 965 data products spread over 8 NASA DAACs and 6 international data centers searchable and retrievable from the EDG. This paper discusses the EDG system, message passing protocols and metadata standards to support various search and query functions across different data centers
