Plans for EO G/S Evolution
• Towards new/improved features/procedures/interfaces – Cal/Val – Geodata access – Bulk delivery – Flexibility for scientific processing and
defined/stabile configuration for operational processing
– Efficient Re-processing
Cal/Val Infrastructure: DEMMIN Durable Environmental Multidisciplinary Monitoring
Information Network
Towards new technologies (private cloud) • Impact analysis: access, data management, and (re)
processing • Security aspects:(e.g. Satellite Data Security Law) • Extend virtualization of computing infrastructure • Evolve to private clouds at EOC sites • … and using/sharing capacity with:
– private clouds from other EO Center sites to increase capacity if needed
– users in demand of IT-capacity (e.g. downstream services) – extend to commercial clouds for peak load and non-
sensitive situation (regarding data security, algorithm security, IT security)
• Archive must reside completely at EOC within the integrated approach (processing, access): data life cycle center

DLR LTDP Implementation
Activities & Status
• Contribute to LTDP Guidelines and Preserved Dataset Content (PDSC) document updates as active LTDP WG & GEO task member
• Performed detailed LTDP Guidelines compliance and impact assessment
• Compiling complete PDSC for TerraSAR-X mission
• Investigating data management concepts to include complete PDSC within EU project SCIDIP-ES
• Contributing to ESA LTDP Architecture
• Starting discussion on concept for using persistent identifiers for EO data in LTDP WG
Guideline level Compliance
A 89% B 71% C 48%
Overall 76%
LTDP Guideline Compliance at DLR
DLR LTDP Experience & Recommendations Experience
• Need for (funded) LTDP still difficult to convey to mission-owners
• Rising awareness noticeable now in EO and other communities (Climate Change Variables…)
• General data preservation experts & tools are available
Recommendations
• Explore LTDP practices and experience of communities outside EO and Earth Science
• Alignment of GSCB LTDP recommendations to standards (e.g. CCSDS OAIS & ACTDR, OGC*) to ensure interoperability
• Tailoring of generic LTDP tools, services, and standards for preservation of EO data
* OAIS - Open Archival Information System ACDTR - Audit and Certification of Trustworthy Digital Archives OGC - Open Geospatial Consortium
DLR HMA Implementation Status • HMA CSW catalogue service
– Embedded in EOWEB server layer, pre-operational since Nov 2011
– Configured for GSC-DA missions TerraSAR-X (4 datasets) and IRS (12 datasets), in addition O3M-SAF (2 datasets)
– Supports standard authentication (SAML) and authorization for individual datasets (within EOWEB), metadata schema updates ongoing
• HMA ordering service – Embedded in EOWEB server layer, DLR operational
deployment scheduled after GCM-IRS ORR Q2 2012 – Used at DLR for IRS ordering – Supports standard authentication (SAML) and
authorization (within EOWEB)
DLR HMA Implementation • TSX-1.SAR.L1b-Spotlight queried in engine.joebrowser.com
via HMA/CSW
HMA Implementation in the Context of GSCDA Phase 2
• Commercial distribution rights for TSX data rest with Astrium GEO / Infoterra GmbH – Partnership ITD, DLR and Werum – DLR HMA Browsing Service can be used directly by ESA – HMA Ordering Service was implemented at TSXX (commercial Ground
Segment Infoterra) based on DLR Implementation – Compliant with the
commercial and regulatory framework (SatDSIG) for ordering of TSX Products
– HMA Orders placed to TSXX are processed internally, checked for SatDSiG compliance, then rerouted and placed via the nominal CIP Protocol to DLR GS
Lessons /Recommendations from GSCDA Project • HMA Protocol must be tailored to accommodate the
commercial and regulatory reality • Implementation was more complex and took more time than
anticipated on all sides • No actual operational experiences from use of HMA can be
reported, as the HMA interfaces exposed by TSXX have not yet been used by ESA CDS.
• Extend support of HMA services for future national missions, e.g. Catalogue/Ordering/Feasibilty Analysis for TSX-2, Online Data Access for EnMAP
• Extend use of HMA interfaces between clients/portals and data centers, example at DLR: EOWEB GeoPortal using HMA CSW/Ordering (currently under development)
