The Earth Observation Depot Network (EODN)

A distributed cloud, open-content distribution network for remote sensing data

The Earth Observation Depot Network (EODN) is a distributed storage service that capitalizes on resources from the NSF-funded GENI and Data Logistics Toolkit (DLT) projects. The Intelligent Data Movement Service (IDMS), a deployment of the DLT on the NSF-funded GENI cloud infrastructure, realizes EODN to enable open access, reduced latency, and fast downloads of valuable Earth science information collected from satellites and other sensors. Beyond basic storage capacity, the IDMS-EODN system includes mechanisms for optimizing data distribution throughout the depot network while also taking into account the desired locality of user data. Accelerating access enables better synchronization of disparate imagery sets and facilitates new cross disciplinary research applications.  Here you can find instructions on how to install a depot.  AmericaView members WisconsinView and MichiganView are working with lead-institution Indiana University to secure future funding to further this effort.  Contact Sam Batzli (WisconsinView) and Nancy French (MichiganView) for details on how to participate.

Physical hardware depots in local infrastructure run the same DLT-RS software stack as in the Cloud, only the deployment and usage model differ. (Source: Dr. Ezra Kissel, Indiana University).
