About University

IGN is the French national mapping agency. Also in charge of the French Forest inventory, IGN gathers roughly 1600 persons. IGN is more and more involved in monitoring activities for sustainable development. IGN has an engineering school: ENSG, with a research center of 5 laboratories and about 70 researchers. ENSG is a 75-year-old school, experienced in training in all geographic sciences (from geodesy to geo-web processing). ENSG counts more than 420 students in 12 cycles. Levels of diplomas range from senior technician and professional license to engineer, masters, and specialized masters. (Mastères Spécialisés®). ENSG operates live long learning and distance learning departments too.


Role in the project

ENSG will be involved in the following:

  • Designing et updating the web site of the EME project.
  • Participation in all meetings including steering committee meeting
  • Participation to the ToT sessions
  • Participation in dissemination/exploitation events.

  • Jean-François Hangouët

Jean-François Hangouët, PhD, divisional survey engineer from the French National Mapping Agency (IGN-F), is currently positioned as head of the geo- imagery department at ENSG. His fields of expertise include cartographical and architectural photogrammetry, map generalization, quality of geographic data, computational geometry. Dr. J.-F. Hangouët, aged 48, also has professional experience in Quality Management Systems. He was involved in the delineation of several maritime boundaries and shows interest for the cross-cultural fundamentals of spatial positioning and cartography. His scientific publications and lectures are characterized by the place given to epistemological elicitation and questioning, such concerns being, he argues, indispensable to the faithful rendering and transmission of knowledge.
