Littoral - Environnement - Télédétection - Géomatique (LETG)

Description succinte

The LETG laboratory (formerly COSTEL -  Climate and Land Use by Remote Sensing) studies geography of the environment. With its expertise in human geography, physical geography and geomatics, its scientific program aims to contribute to knowledge on nature-society interactions through a modelling and integrative approach lying at the geographical interfaces between land, sea and atmosphere.

The laboratory focuses on two specific investigative areas, which both face a variety of issues that are directly or indirectly linked to the multi-scalar consequences of climatic and socio-economically driven global changes: littoral (the sea and coastal catchment areas) and continental environments.

The experiments carried out using digital innovations feed a reflective and critical approach to concepts and methods while remaining attentive to public action, hence the organization of the scientific program into three research themes:

  • Littoral
  • Continental Environments
  • Remote sensing (Geomatics)

These three themes are methodologically supported by RASTER, the French Scientific and Technical Support Network for Research.

LETG, which is attached to the Institute of Ecology and Environment (INEE) of CNRS, is present on six sites in the west of France: Angers, Brest, Caen, Dinard, Nantes and Rennes. It operates under the CNRS, EPHE, Université d’Angers, Université de Brest, Université de Caen, Université de Nantes and Université de Rennes 2.
