GENESI-DR, (Ground European Network for Earth Science Interoperations – Digital Repositories), has the challenge of establishing open Earth Science Digital Repository access for European and world-wide science users to seamlessly access and share all data, information, products and knowledge originating from space, airborne and in-situ sensors. GENESI-DR shall operate, validate and optimise the integrated access and use available digital data repositories to demonstrate how Europe can best respond to the emerging global needs relating to the state of the Earth, a demand that is unsatisfied so far.GENESI-DR has identified the following objectives:-To provide a base for (establishing) a world-wide e-infrastructure for Earth Science with European leadership-To provide guaranteed, reliable, easy, effective, and operational access to a variety of data sources, and demonstrate how the same approach can be extended to provide access to all Earth Science data-To harmonise operations at key Earth Science data repositories limiting fragmentation of solutions-To demonstrate effective curation and prepare the frame for approaching long term preservation of Earth Science data-To validate the effective capabilities required to access distributed repositories for new communities, including education, and assess benefits and impacts-To integrate new scientific and technological derived paradigms in operational infrastructures in responds to the latest Earth Science requirementsGENESI-DR builds upon the existing, operational and focused Earth Observation (EO) European infrastructure and involves key Earth Science centres responsible for operational data acquisition, processing, archiving and distribution. GENESI-DR involves key partners of the Ground Segment Coordination Body (GSCB), and it is aligned to the ESA EO Programme Board strategic vision for long term data access and preservation, thus efficient use of already existing and planned developments is guaranteed
