1. 1 To facilitate access to satellite data THEIA Land Data Centre Pierre Maurel, GEOSUD Coordinator Nicolas Baghdadi, THEIA Scientific Director Marc Leroy, THEIA Technical Director CEOS Strategic Implementation Team (SIT) Technical Workshop 16th ­18th September, 2014, Montpellier

2. 2 Fact : Satellite imagery is under-used by public actors (scientific community and policy makers) Bottlenecks : costs, processing, user support  Need of a new model to facilitate access to satellite imagery Mutualisation  Multi-licence imagery  overcost from +30% to +50% Free access to « Public actors » Foundation in 2012 of a national structure, scientific and technical: THEIA = Land Data Centre THEIA = inter-institutions structure funded jointly by 9 public French partners involved in Earth observation and monitoring: CEA, CIRAD, CNES, CNRS, IGN, INRA, IRD, Irstea, Météo France + CEREMA since June 2014 Context 2

3. 3 Answer the needs of the science community and national policy-makers in terms of products, methodologies, and training related to the observation from space of land surfaces Facilitate access and use of space data for a large user community Federate efforts at national level and make them visible at European and international levels THEIA is based on a Space Data Infrastructure (SDI), organised around projects / initiatives such as: Geosud, Kalideos, Pléiades, Postel, Spot World Heritage… Objectives 3

4. 4 THEIA is based on : a distributed Space Data Infrastructure (SDI) the components of which are developed by CNES and by GEOSUD, an integral part of THEIA a network of Science Expertise Centres a Science and User Board an Executive Board: Nicolas Baghdadi (Irstea), Marc Leroy (CNES), Selma Cherchali (CNES), Jean-François Faure (IRD), Pierre Maurel (Irstea), Magali Stoll (IGN) a Steering Committee A portal giving access to products and services (www.theia-land.fr) THEIA Land Data Centre : Structure 4

12. 12 The THEIA SDI is a federation of data centres distributed geographically in France, connected by core mutualised services This architecture can evolve and include other Processing and Distribution units, possibly European IDS THEIA Structure

13. 13 THEIA Products 2013 - 2016

14. 14 SEC = grouping of laboratories developing innovative methods on Land thematic area Two SEC categories –SEC « Product » : around a value-added product. They can associate one or several labs. Example : SEC Land Cover In the process of being defined. As of today around 20 propositions of such SEC –SEC « Regional » : the mission is to federate and animate the science community at the regional scale, and to participate to training of the community in particular on the products developed by the SEC « Product » As of today 4 SEC « Regional » identified : Languedoc-Roussillon, Midi- Pyrénées, Alsace, Aquitaine Science Expertise Centre (SEC) 14

15. 15 To structure a national institutional remote sensing sector : –To answer the needs of scientists and policy makers – Associating intermediary actors of the sector (public, private) – For a perenial access to data, equipment, products and services Priority to national satellites and to shared-cost data Cluster of complementary and quality-controlled imageries  Pleiades images (IGN, CNES, GEOSUD)  National coverage GEOSUD  HR products from the GEOSUD receiving station (SPOT 6-7…)  Sentinel-2 images (Copernicus)  Spot World Heritage … –Opening to international cooperation (Southern countries) –As a concertation platform to elaborate jointly national strategies towards Europe and beyond Towards a national institutional remote sensing sector

16. 16  To be consolidated with the support of main beneficiaries: ministries, regional governments, research organisations … – To secure on public funding durability of the core infrastructure allowing public and private innovation – To adapt business models to the nature and to the beneficiaries of the value added products and services – To capture a share of the added value to sustain the core infrastructure THEIA Business model

17. 17 a THEIA Collaborative Ground Segment has been proposed to ESA – ESA is putting in place a system of Collaborative Ground Segments to assure the distribution of the huge amount of Sentinel data in the Member States – The national science community has strong interest to S1 (radar imagery), S2 (HR optical imagery) et S3 (LR optical imagery) – The THEIA Collaborative Ground Segment will be linked to the national PEPS (Sentinel Product Exploitation Platform) Sentinel data mirror site distribution of the Sentinel data to the national community facilitation of access to data processing tools 17 THEIA European strategy

18. 18 The THEIA Collaborative Ground Segment includes 3 components : – Component 1: Processing of S2 (atmospheric corrections and monthly composites), on areas totalising 5 Mkm2 – Component 2: provision of value added products on various regions worlwide, such as land cover, change detection, vegetal biogeophysical variables, albedo, water level, … – Component 3: user support for the use of value added products 18 THEIA European strategy

19. 19 THEIA European strategy To act in such a way that the products developed by THEIA SEC have a European future in Copernicus framework  Example: Surface reflectance Sentinel-2  Example: Lake and river water level with Jason and Sentinel-3  Example: Vegetal biogeophysical variables Insert THEIA in European network  Knowledge and project network » Most natural vector: reply to H2020 Call for Tenders  Space Data Infrastructure (SDI) network » The idea is to connect the THEIA SDI in a network of European SDIs » Work on SDIs interoperability when possible » Approach followed byTHEIA : participate if possible to the ESA TEPs (Thematic Exploitation Platforms)
