1 Contribution of Pléiades VHR imagery in reactive mapping in France Hervé Yésou SERTIT Aurélie Escudier DGPR/SRNH/SCHAPI/MHO & SERTIT rapid mapping and research team

2 Objectives and context Promote and facilitate the use of Earth Observation space technologies for the management of natural and technological risks for: French institutional users, Ministry of the Environment, Ministry of Finance. CNES commitment under the Framework Convention with MEDDE Thematic Action n 5 (2011) Previous experiences within ORFEO Program: early studies initiated in 2009 with SCHAPI/SPC, SERTIT RTU : on the request of different French Ministries services. Pléiades imagery was tasked in emergency following disaster events on the national territory Pléiades data were exploited within User-exercise

3 2013: 4 rapid mapping actions within the RTU framework: Agly (March) Marne, Yonne, Serein, Armançon (May) Sarre (June) Gave de Pau, June 2013 Pléiades VHR data acquired in rush mode Images processing and analysis, crisis products generated in normal office hours (excepted for Marne Yonne, geo information in rush mode, i.e. less than 6 hours after data reception) 2014: 1 action - the French Atlantic Coast (January) RTU - Pléiades tasked in emergency for flood events Gave de Pau Marne - Yonne Agly Sarre Products generated in pdf and vector format: Water extent (flooded and permanent) Impact assessment on housing Impact assessment on infrastructures

24 Exercice Séisme 13 Antilles Headquarter exercise : facing a major earthquake in French Caribbean's 26 & 27 February 2013

25 SEISME13 Exercise Context and objectives Headquarter exercise (2 days) To test the management of a major crisis in the context of the simulation of an exceptional magnitude earthquake of 8.0 in French Caribbean's. How can the space component can be integrated within disaster management procedure? Awareness-raising action. CNES commitment under the Framework Convention with MEDDE Thematic Action n 5 Promote the development of satellite applications for the management of natural and technological risks.

26 SEISME13 Exercise Context and objectives On the basis of a scenario defined by BRGM & MEDDE (CMVOA- Cellule ministérielle de veille opérationnelle et d'alerte) with precise specifications in term of timing, stakes and key elements, forecasted impact of such disasters. Application of International Charter procedures: Triggered by the French Civil Security (DGSCGC/COGIC), CNES as Project Manager, SERTIT as Service Provider for value-added products. Exploitation of Pléiades VHR archives data as reference and for simulated crisis images.

27 Users needs expression - stakes and key elements Transportations infra structures (state and accessibility) Airport Roads/bridges Harbor Energy infra structures Thermal power station Gas and fuel warehouses Location possible for generating sets Health Location of IDP camps Potential location of water plant units Cold storage plant Information on state of hospital Plus classical / more generic Damage on buildings With specific focuses on jail, secondary school SEISME13 Exercise

29 Industrial/residential areas, infrastructures, army camp 29

30 Jarry industrial area: major implantations and Seveso sites 30

31 SEISME13 Exercise Rapid mapping products types: 8 reference spatio maps P01-P08 Administrations et rescue (firestation/police) Sensitive Infrastructures 1: to 1: simulated crisis spatio maps P09-P18 Impacts on infrastructures (harbor, roads, bridges, airport runway) Impacts on stakes areas Damages on buildings 1:1500, 1:1000.

32 Thermal plant: fire and smoke Industrial building partially collapsed Jarry industrial area: Simulated impact on energy plant 32

33 Simulated impact on airport runway Soil liquefaction Impacted runway Collapses and soil liquefaction

34 Simulated impact on sensitive warehouses Industrial building devastated Cold storage plant Apparently unharmed

35 Potential site for water plant IDP camp Collapsed buildings Collapsed buildings Collapsed buildings Simulated impact on buildings 35

36 Conclusion Real interest of users for Pléiades VHR images use in case of disaster rapid assessment and awareness of Earth Observation data use in the framework of exercises. Implementation of the operational loop between the different services involved in disaster management. Definition of the role of each characters (End-Users, Focal point/project Manager, Value added, dispatching schema) Confirmation and strengthening of: Pléiades operational capacities: tasking/production Pléiades thematic information content thanks to its resolution/spectral coverage Quick access to this thematic information useful to organize recovery field works
