1. Jérôme Gasperi GSCB Roma, Italia - April 11th, 2013 Current and planned activities
2. Current infrastructures & platforms Land Surfaces Thematic Center Altimetry Ground Segment Phoeßus On going R&Ts WPS Linked data Planned activities OWS-10 OGC testbed
3. Land Surfaces Thematic center (PTSC) A metacatalog to facilitate interoperability Current infrastructures & platforms
4. "The objective of the center is to facilitate the study of issues related to the impact of anthropogenic pressures on climate and ecosystems, quantify and model the water cycle and carbon monitoring developments of societies and their activities, understand the dynamics of biodiversity."
5. To achieve this objective, the center will develop and make available to the scientific community data, products, processes and services related to the observation from space land surfaces.
6. CNES METACATALOG GEOSUD Kalideos Land Surfaces Portal POSTEL Spirit Hydroweb Landsat South France IGN Take5 PTSC by end of 2013 ~1000 products France Very High resolution cover ~ 120 000 products OpenSearch (1) OpenSearch (1) CSW ISO CSW CIM (1) OpenSearch to be aligned with HMA-S specification
7. CNES METACATALOG GEOSUD Kalideos Land Surfaces Portal SENTINEL 2 SPOT Archive POSTEL Spirit Hydroweb Landsat South France IGN Take5 PTSC mid to long term objective ~ 120 000 products ~1000 products France Very High resolution cover ~ 400 000 products Huge amount of products Whole Earth CSW ISO CSW CIM OpenSearch (1) OpenSearch (1) (1) OpenSearch to be aligned with HMA-S specification
8. V0 officially opened by mid april 2013 http://ptsc.teledetection.fr !
9. Altimetry Ground Segment On demand distributed Processing Current infrastructures & platforms
10. Simplify access to product "Get what you want" - provide data extraction service to limit download to a subset based on geographical extent, time interval and/or physical parameters - [short term objective] "Get fresh products" - process data on demand to shorten delivery time (e.g. no need to wait for a full reprocessing of Level 2 products with newer algorithm/model/etc.) - [mid term objective]
11. Phoeßus Processing High level Orchestration Engine and BUsiness Services Current infrastructures & platforms
12. A fully integrated workflow execution framework Esay integration of processing chains Ressource management User friendly GUI Hardware configuration, allocation and monitoring
13. Phoeßus Inventory Production Processing server Processing server Execution Events Processing center Event manager Workflow engine Administration & supervision Job management system
14. Phoeßus Inventory Production Processing server Processing server Execution Events Processing center Event manager Workflow engine Administration & supervision Job management system Monitor and Command of the Data Production Centre (startup/shutdown, etc. Monitor and Command of the hardware components status (nodes of the clust On Line Help of the Data Production Centre No human intervention is required in nominal operation Administration & supervision
15. Phoeßus Inventory Production Processing server Processing server Execution Events Processing center Event manager Workflow engine Administration & supervision Job management system Detects processing events described in an XML configuration file - data events, time events, stream events, web services events (WPS), user events Event manager
16. Phoeßus Inventory Production Processing server Processing server Execution Events Processing center Event manager Workflow engine Administration & supervision Job management system Generates & manages workplan automatically or manually (MMI) Orchestrates & parallelizes the execution according to execution events (errors, crash) and operator orders (stop, resume, cancel, change priority, replan) Workflow engine
17. Phoeßus Inventory Production Processing server Processing server Execution Events Processing center Event manager Workflow engine Administration & supervision Job management system Processes the parallelization level on run-time Supports both CNES-LAI and ESA-JobOrder interfaces, Monitors and controls the execution of the software executable delegated to Phoebus-JobManagement component. Processing server Processing server
18. Phoeßus Inventory Production Processing server Processing server Execution Events Processing center Event manager Workflow engine Administration & supervision Job management system Distributes the software executable onto the cluster of processing servers on an optimized way. Support 3 different types of distributed applications (Pléiades proprietary, DRMAA vA API (e.g. Torque/Maui), Cascading Hadoop) Job management system
19. Performance and scalability IPU-Pleiades Center (hosted in SpotImage premises) - 500 images/day generated thanks to cluster of 52 servers (octo-core) - Raw images in case of urgent Defense needs) are delivered in less than 7mn - High level corrected images are delivered in less than 25mn
20. Used by Pleiades, GAIA and CSO ground segments
21. WPS Assisted land cover classification On going R&T
22. From pixel... Remote sensing image
23. From pixel... Remote sensing image ...to information Land cover thematic map
