1. Emerging satellite sources Geneva, February 3rd 2011 David Hello – ASTRIUM Geoinformation Services | Spot Image IPCC – GEOSS workshop SESSION 5: EXTREME EVENTS AND DISASTERS

2. 27/09/2010 - 2 Introduction and rationale  Workshop motto « provide guidance on how GEOSS can improve the delivery of multi-disciplinary data and data products to the climate impacts, adaptation, and vulnerability research community »  I’m not a scientist … sorry. Point of view of someone involved in emergency operations.  EO can support all phases of the disasters management and some mechanisms already exist at International or Regional level to foster and ease the use of EO data for Disaster Management  The focus has been so far given on EO contribution to « emergency response » (so called Rapid Mapping) but …  From the users’ perspective, EO-based analysis may be even more relevant for pre and post crisis phases:  assessment of socio-economic vulnerabilities  assessment of socio-economic impacts in the long term  What future satellite should bring in addition to what exist today ?

3. 27/09/2010 - 3 Table of content  Introduction and reminder of Earth Observation contribution to Disaster Management  The current landscape  What are users’ requirements ?  What are the current data sources ? What are the EO-based International mechanisms to support Disaster Management ?  Do EO-based services fulfil users’ requirements ?  The near and the far future  What are Earth Observation satellites key features ? How can they evolve ?  What the next generation of EO satellites should bring ?  Conclusions

4. EO for Disaster Management

5. 27/09/2010 - 5 Contribution of EO to disaster management Structural parameters - DEM - Vegetal cover - Soil cover Vulnerability mapping Population Infrastructures … Dynamic parameters Vegetation wetness Global monitoring Rapid Mapping Disaster mapping Rapid damage assessment Detailed damage assessment - Socio-economic impact - Environmental impact Global assessments - e.g. Burn Scar Mapping POST DISASTER CRISIS PREVENTION / PREPARDNESS User databases Input to risk analysis models Input to forecasting models Information support to rescue operations Impact assessments Experience feedback  Still some Research & Development work to do in particular regarding alert systems, vulnerability assessment etc.

8. 27/09/2010 - 8 The International Charter Space and Major Disasters Funded in 1999 by CNES and ESA Joint by: ASC (Canada) NOAA (USA) ISRO (Inde) CONAE (Argentine) JAXA (Japon) USGS (US) BNSC/DMCii (UK) CNSA (China) The International Charter is agreement (on a best effort basis) between international space agencies to supply emergency organizations, with a timely, free and coordinated access to EO data in case of major disaster

9. 27/09/2010 - 9 Other emergency support mechanisms  Sentinel Asia  Sentinel Asia is a voluntary basis initiative led by the APRSAF (Asia- Pacific Regional Space Agency Forum) to support disaster management activity in the Asia- Pacific region by applying the WEB- GIS technology and space based technology, such as earth observation satellites data.  UNSPIDER – SpaceAid  SpaceAid is UN-SPIDER’s framework to facilitate fast and efficient access to space-based information for countries, international and regional organizations. This includes all types of information provided by earth observation satellites, communication satellites and global navigation satellite systems.  SERVIR  Enabling the use of earth observations and models for timely decision making to benefit society

10. 27/09/2010 - 10  SAFER project co-funded by the European Commission (FP7 program) – Coordinated by Astrium Services | GEO  SAFER is preparing the future European Emergency Response Service (to be fully funded by EC from 2012 onwards) SAFER and the GMES Emergency Response Service  SAFER Focal Point on call duty 24/7  Rapid Mapping Service Providers on call duty 24/7  EO coordinated data access 24/7 (through ESA)

14. 27/09/2010 - 14 Geographic reference map / Dam failure impact Detailed reference map over Abidjan (Ivory Coast) User = WHO Modelisation of the impact of a natural dam failure following a landslide (Hunza river, Pakistan, March 2010) Crucial need for in-situ / ancillary data to complement EO data !

15. 27/09/2010 - 15 Current limitations and required improvements (lesson learnt after 2 years of operations)  Response time for Emergency Response (target: 24h)  current performance to be improved  Main delays in image acquisition (see next slide)  Tasking and data acquisition still to be improved  Product delivery, incl. to in-field operatives  Commitment on delivery  No guarantee on delivery or timing.  Delivery mainly to the headquarters. Increasing demand of the in-field operatives and for integration in GIS tools.  Revisit and situation monitoring  in case of long duration events.  Increasing demand for pre and post disaster analysis  E.g. for complex vulnerability analysis (Xynthia storm in France in 2010)  Increasing demand for high and very high resolution images and products

16. 27/09/2010 - 16 Responsiveness of Earth Observation systems Event Early warning signals or anticipation Activation decision by user Activation of the operational chain Satellite tasking First good image available Information product available Product distribution to users (Headquarters and in-field units) Uplink Downlink

23. 27/09/2010 - 23 GMES dedicated missions

24. 27/09/2010 - 24 The far future … Geostationary EO satellite  Enhanced availability  The GEO satellite observes only over the areas of interest  GEO located instruments can use any transient opportunity provided by clouds absence  Short revisit times  Continuous data downlink  ESA has recently performed three studies on optical EO from GEO:  Low to medium resolution observation in “Alternative GMES architecture”. Resolution 500 m.  Medium to high resolution observation in “GeoOculus”. Resolution 20 m over Europe.  Very high resolution observation in “Towards 1-m from GEO”. Resolution 4 m over Europe  BUT … HR from GEO has well known disadvantages e.g. degraded resolution and radiometry, distortion as the line of observation moves away from Nadir etc.

25. Conlusions

26. 27/09/2010 - 26 Conclusions  On the Space component side  The continuity of EO missions needs off course to be insured in order to fulfill users’ requirements on a sustainable way (current trend = increase number of disasters + increased severity )  The development of new missions/sensors to better fit with users’ expectations worldwide is a key success factor  On the application side  The future GMES Emergency Response Service (as well as other GMES services e.g. land, ocean, climate, security, atmosphere) is a good candidate to contribute to map climate impacts as well as socio-economic vulnerabilities based on EO analysis  GMES products are deamed to be fully and freely accessible for scientific work !  Don’t forget in-situ data !  Census data, socio-economic statistics  Some GMES initiatives in progress (e.g. GISC/EEA)
