  2. ENVISAT D-PAC Status • After the end of the Commissioning Phase the PAC is performing its nominal tasks on behalf of ESA, which comprise archiving, processing and user services for the • ASAR instrument • The atmospheric payload SCIAMACHY, MIPAS, GOMOS (collaboration with Fin-CoPAC for GOMOS) • Data reception from ESA is via tapes and satellite link • Data dissemination to users is via CD-ROM, Exabyte, ftp and in the near future DVD delivery • Supporting national projects MERIS downlinks are received with DLR‘s Neustrelitz Ground Station • Current storage volume 28 TBytes B. Buckl

  3. D-PAC Archive and Processing System • Multimission Archive: • Envisat-Part: • 3600 Slots • up to 70 TB on media • 500 GB Online-Cache • Processing-Hardware: • IBM SP2- large scale system 4 I/O nodes 16 Processor nodes • IBM Linux-Cluster 35 PC nodes B. Buckl

  4. TerraSAR-X Introduction TerraSAR-X is a German next-generation high-resolution X-band radar satellite • TerraSAR-X is the logical scientific and technological enhancement of the very successful national missions X-SAR (1994) and SRTM (2000). • Newly developed technologies will be operated for the first time Main goals of the mission are: • Provision of TerraSAR-X data and products for scientific applications(--> public interest), • Commercial utilisation of remote sensing data(--> by industry). • Public Private Partnership (PPP) B. Buckl

  5. TerraSAR-X TerraSAR-X Payload Ground Segment (DFD/IMF/GSOC/HR) • Tasks: • Reception • Acquisition planning (with GSOC) • Processing • Calibration (HR) • Archiving and Distribution • Support for scientific Users • Interface to Astrium/Infoterra • Challenge: • Novel Radar System • Up to 600 Datasets or ~70 GB per day • Processing in near-real time B. Buckl

  11. TerraSAR-X Schedule • Critical Design Review Feb. 2004 • Technical Acceptance Feb. 2005 • Ground Segment Readiness Sept. 2005 • Launch planned for Oct. 27th, 2005 • Commissioning Phase until April 2006 • followed by Operational Phase B. Buckl

  12. GMES Service Elements (GSE) ESA statement: GSE will deliver policy-relevant services to end-users, primarily (but not exclusively) from Earth Observation sources. GSE is a key element of GMES, because it will enable end-users to become key players in the move from present generation Earth Observation satellites to future European systems that will deliver vital information on global environment and security. • Funded by ESA • DLR participation in two GSE projects: • SAGE: water pollution risk and soil sealing maps for water management and soil protection led by InfoTerra GmbH • Forest Monitoring: Forest area and land use change mapping led by GAF • Task: Analysis of existing systems and infrastructure, development of scenarios for the establishment of the GSE infrastructure B. Buckl

  13. GMES Service Elements (GSE) Examples of identified challenges (from SAGE) • European EO infrastructure is heterogeneous; for different satellite system different organisations are responsible and dedicated ground segments are established • The crucial problem for optical data is the difficulty to get cloud-free data over a certain region at a defined time period • Service Infrastructure elements are not operational public service systems; information is produced on project level mainly. High management effort (e.g. for team coordination, establishing production). Low update cycles. • Some components of Service Infrastructure elements (e.g. interpretation and validation) are characterised by a high amount of manual and interactive work. This leads to bottlenecks in the process chains and to reduction of service performance • Scaling-up of Service Infrastructure elements to a European dimension is currently restricted by • the limited availability of trained interpretation staff with specific regional/local knowledge • the lack of automated and standardised production chains • the limited availability of auxiliary data and (cloud-free) EO data.

  15. SRTM Production SAR Image Products B. Buckl

  16. SRTM Production Product Availability • Products can be searched and ordered using EOWEB (http://eoweb.dlr.de) • Products from crisis or security sensitive regions are not available to the public. • If you are interested in these or want to place bulk orders, please contact Franz.Paetzold@dlr.de • Product coverage (as of Sep. 10th, 2003) • Europe except Italy (provided by ASI) and Scandinavia • Africa • Asia (western part to ca. 70 deg E) • North America without the Rocky Mountains • South America without the Andes • Australia B. Buckl

  17. IKONOS • Receiving station deployed at the Operpfaffenhofen campus in June 2003 • DLR operates the station, processes and archives the data (cooperation contract with European Space Imaging) • Coverage is from the polar circle to the Sahara desert and from the east part of the Atlantic Ocean to the Black Sea Subsampled IKONOS image showing parts of the the Oberpfaffenhofen campus including the IKONOS receiving station B. Buckl

  18. Charta on Space and Major Disasters - Portugal Fires The very dry summer 2003 caused severe fire damage in Europe, especially in Portugal. On August 5th, the Portuguese “Servicio Nacional de Bombeiros e Proteccao Civil” activated the “International Charter on Space and Major Disasters”. On request of ESA the DFD took the project management as well as data distribution and analysis for this Charta call. During the 18 days of Charta execution 34 NOAA-AVHRR, 3 ENVISAT-MERIS, 9 SPOT, 3 BIRD, 1 IKONOS geocoded products, 17 NOAA-AVHRR fire masks as well as 2 MERIS and 2 SPOT burned area masks have been delivered to the fire fighters. After the Elbe flood last year this was another successful example of the effectiveness of the Charta on Space and Major Disaster. Forest fires in Portugal - BIRD image from Aug. 4th Coverage is ca. 190km x 140km, largest fires are 3km x 5km BIRD is a DLR infrared satellite able to detect hotspots with a resolution of 250 m. Especially suitable for measuring the intensity and extension of surface fires. B. Buckl
