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 nonsensitive 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
Experience
DLR LTDP Experience & Recommendations
• Need for (funded) LTDP still difficult to convey to missionowners
• 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)
