RESUME:
Titulaire d'un diplôme d'ingénieur en agriculture, spécialisé en télédétection, JF DESPRATS a débuté sa carrière au BRGM en 1991 comme responsable d'études statistiques en agriculture dans le cadre d'un projet européen. Il a par la suite été responsable de projets liés à l'environnement, à l'hydrogéologie et à la cartographie, dans le domaine des SIG et de la Télédétection.
Il intervient en tant que chef de projet ou bien en collaboration sur des projets liés à l’environnement (sols, agriculture, érosion, ..) que ce soit au niveau régional, national ou international. Il est amené dans le cadre de ces activités à réaliser des missions d’expertise en pays anglophones ou hispanophones.
Il a assuré des formations en SIG et télédétection (France-GDTA 2000, Mexique 2000, Chili 1997, Hongrie 1997, Iran 2001, France Ecole des Mines 2009-2010-2011).
JF DESPRATS holds a degree in agricultural engineering, specialized in remote sensing. He started his career at BRGM in 1991 as manager of statistical studies in agriculture within the framework of a European project. He was then in charge of projects related to the environment, hydrogeology and cartography, in the field of GIS and Remote Sensing.
He intervenes as a project leader or in collaboration on projects related to the environment (soils, agriculture, erosion, ..) at the regional, national or international level. In the framework of these activities, he is required to carry out expert missions in English or Spanish speaking countries.
He has provided training in GIS and remote sensing (France-GDTA 2000, Mexico 2000, Chile 1997, Hungary 1997, Iran 2001, France Ecole des Mines 2009-2010-2011).
