Background

Hervé Yésou received his Ph.D in 1993 in "merging of remote sensing data for geological applications" from the University of Strasbourg. A member of SERTIT', Herve Yesou is a remote sensing specialist in charge of the hazards and environmental applications.

He is a key member of the SERTIT rapid mapping service, being involved in the Space and Major Disaster Charter action, triggered after major floods such as Gard 2002; Haiti 2004; Romania 2005, Katrina 2005, Central European Flooding 2006, Nargis-Maynmar 2008, Haïti 2008, Niger 2012, Madagascar 2013. Within the GMES SAFER project, in 2010 he has conducted rapid mapping actions for the events such as Xynthia France, Var France, Mozambique, Croatia, Moldavia and the forest fire in Haifa region (Israel). He was also involved in few exercises for Civil Defence, EUROMED 2007, Richter 2008, or within the former EU GMOSS network (GNEX06, GNEX 07), and more recently, Seisme 13 over la Guadeloupe. Within the CNES thematic commissioning Phase of Pleiades, he also conducted actions over Gave du Pau flood, in June 2013. Since December 2013 he is involved in the Rapid Analysis and Spatialisation Of Risk (RASOR) project that will develop a platform to perform multi-hazard risk analysis to support the full cycle of disaster management, including targeted support to critical infrastructure monitoring and climate change impact assessment.
In the 90's, he participated to major EO programs through pilot projects on the exploitation of SAR and optical data: ERS1-2, SPOT 4 MIR and SPOT 5 SIR C/X-SAR for ADRO Radarsat. He was coordinator for an ENVISAT project on wetland monitoring in France and Poland as well as the ESA Water and Fire project on the exploitation of SAR time series and VHR optical data. (Grassland mapping and management, embroachment characterization, etc). The latest years, he was also PI for ALOS, Cosmo Skymed, Deismos, TakeFive experiment aiming to simulate the future Sentinel2 time’s series, Pilot projects. More recently he is involved in Terra SAR X projects focused on archive exploitation, Tandem X DEM generation and qualification, analysis of the extra-wide and very high resolution of the new Terra SAR X modes for wetland and lakes characterization, mapping and monitoring. These actions are carried out both over European and Asian test sites.
Been the European leader of the Flood DRAGON project (2004- 2012), he is now conducting the Wetland-Flood” DRAGON 3 project (2012-2016) during which sustainable development and biodiversity are major skills over major Chinese wetlands, mostly Poyang lake and Anhui Lakes plus Dongting lake, Zhalong. On the topics of monitoring in term of water resource, inundation periods, and their impacts on vegetation with in addition epidemiological implications. Epidemiology is the latest field of application in which SERTIT is involved. Studies began in 2007, by the characterization of the habitat of Schsitosiomasis vector in Poyang lake region. The innovative part of this work was to taking in account the dynamic aspect of monsoon floods and vegetation growth on a monthly basis. A second disease is now handle, Malaria in an urban context in Western Africa. In Asia, he participates also in Planet Action projects over sensitive mangroves and wetlands areas in Vietnam (Tram Chim, in Plaines de Joncs and Central-Western of China (Rouergai and Napahai wetlands).
Since 2000 he has been the external expert for CNES on the definition of VHR future sensors, participating to the ORFEO thematic groups and now he is the leader of the ARCTOS expert panels on risk management for definition of the post Pleiades system. For CNES, he also conducted a study on thematic feasibility of GEO-LEO system for environmental and risk management. Since 2012, he joined the Science Definition Team of the future Nasa_CNES altimetric mission, SWOT.

Activities in education

Hervé Yésou has presented advanced courses on Image Processing, since the end of the 90's within the framework of cooperation projects in West Africa and Europe. In 2003, he also ensured a lectures and training in China on the exploitation of Earth Observation data for disaster rapid mapping in the framework of the Sino French Catachina project. He also regularly participated to seminars on the topics of natural hazards organized at master and doctorate levels (Athens, Telecom Paris) or for a wider public. He also participated to part of ESA Training courses: Lisbon 2007, Pragua 2009, Krakow 2011, Athens 2013, Hanoi 2008, and the ESA-MOST “Dragon 2 advanced Land Training course series ”, Wuhan 2008, Lanzhou 2010, Beijing 2012, Nanchang 2014. In December 2014, he participated to the Do Son School, on Environmental monitoring from Space, organized by CNRS, VAST, IRD and CNES in Hanoi-Do Son, Vietnam. Since 1990, he has supervised more than 25 research students to graduation (MSc) in optical and radar remote sensing applications for environmental/hazards domains.

Distinctions / Memberships

Hervé Yésou has been consulted as an expert on water and Remote sensing Programmes for national (ANR) and international projects (Canada, Luxembourg, EU, and Portugal). He is an active member of the ESA Category-1 Advisory Group and participates to ESA scientific committees.
He has an important scientific journals reviewing activity: International Remote Sensing, since 1995, Computer and Electonics in Agriculture, Comptes Rendus de l'Académie des Sciences, IEEE trans Rem. Sensing, Revue Télédétection, Bull SGF.
