UMR LETG

What UMR LETG does

UMR LETG (Unité Mixte de Recherche 6554: Littoral, Environnement, Télédétection – Géomatique) is a French public research laboratory founded in 1996 by CNRS and jointly supervised by CNRS, Nantes Université, Université Rennes 2, and Université de Bretagne Occidentale (UBO). It operates across three sites in Brest, Nantes, and Rennes (with Plouzané as the registered headquarters), employing a multi-disciplinary team that integrates human geography, physical geography, and geomatics. The laboratory's core research mission is to understand interactions between nature and society through environmental geography, with a particular focus on land-sea-atmosphere interface modeling, climate analysis, and socio-environmental dynamics.

The laboratory's technology portfolio centers on a platform architecture branded Le RASTeR, which bundles INDIGEO (a geospatial data infrastructure), POPS (a research project management tool), and CartABl (an interactive cartographic visualization tool), alongside specialized research platforms including the D2T drone-based terrain remote sensing platform, CHOVE-CHUVA (satellite-based socio-environmental monitoring in the Brazilian Amazon), URBA-CLIM (urban climate analysis), and RUN. Complementary outputs include the Atlas bleu publication portal and an active Gitlab repository. The laboratory publishes through the HAL open-science archive (439+ documents on individual researcher profiles) and disseminates work via international conferences, an institutional website (letg.cnrs.fr), and a LinkedIn presence.

UMR LETG does not operate a commercial revenue model. Activities are funded through CNRS core allocations, contributions from the four supervising tutelles, and competitive grants from bodies such as ANR (e.g., DURAMAZ 3). Customer relationships are institutional rather than transactional: the lab serves academic and research collaborators (CNRS, University of Arizona, Quebec universities, French partner universities in Nice/Lyon/Bordeaux) and produces outputs that inform public policy and government environmental strategies. End 'users' of its research include participatory Amazonian communities engaged through DURAMAZ, doctoral trainees, and the broader open-science community. The laboratory is governed by Director Cyril TISSOT, with Thierry DAUXOIS (President-Director General of CNRS) serving as Director of Publication.

Core offering

UMR LETG is a French public research laboratory conducting environmental geography research focused on the interactions between nature and society through integrated modeling at land-sea-atmosphere interfaces. The unit develops and operates a suite of research platforms and tools (Le RASTeR, INDIGEO, POPS, CartABl, Plateforme D2T, CHOVE-CHUVA, URBA-CLIM, RUN, Atlas Bleu) supporting geospatial data management, drone-based terrain observation, urban climate analysis, and Amazon socio-environmental monitoring. Outputs include peer-reviewed scientific publications, open data, expert contributions to public policy, and doctoral researcher training.

Product overview

UMR LETG is a French research laboratory (Unite mixte de recherche) specializing in geography of the environment, focusing on littoral, environmental, remote sensing, and geomatics research. The organization operates a platform-plus-modules architecture centered around Le RASTeR, which provides research support services including INDIGEO (data infrastructure), POPS (project management), and CartABl (interactive visualization). Additional offerings include the Plateforme D2T for drone-based terrain remote sensing, the Atlas bleu portal for research outputs, and specialized research tools such as CHOVE-CHUVA (Amazon rainfall monitoring), URBA-CLIM (urban climate analysis), and RUN. The laboratory also develops the CHOVE-CHUVA Earth observation web platform for socio-environmental monitoring in Brazil.

Others

• USGS Earth Resources Observation and Science (EROS) Center: U.S. federal center managing Landsat and Earth observation data archives — thematically aligned with UMR LETG's environmental remote sensing work and a potential international data-partnership counterpart, though operating at much larger scale under a different institutional model.

Direct peers

• CESBIO (Centre d'Études Spatiales de la Biosphère): UMR 5126 CESBIO is a Toulouse-based CNRS joint research unit focused on remote sensing of the biosphere, surface processes, and land use — directly comparable to UMR LETG in being a French CNRS UMR combining environmental remote sensing (satellite, UAV) with Earth system research and data infrastructure.
• UMR ESO (Espaces et Sociétés): CNRS UMR 6590 with research sites including Nantes — directly comparable to UMR LETG as a French geography UMR studying spaces, societies, and environmental dynamics in western France.
• UMR PASSAGES: Bordeaux-based CNRS UMR (UMR 5119) studying spatial dynamics, territories, and societies — overlapping with UMR LETG's human geography research and Western France institutional ecosystem.
• Theia (French Land Surface Data Centre): French national data center for continental surface remote sensing products, closely comparable to UMR LETG's INDIGEO infrastructure — both deliver geospatial environmental data services to French research and public-policy communities.
• UMR GEODE (Géographie de l'Environnement): Toulouse-based CNRS UMR focused on environmental geography, combining human geography, physical geography, and geomatics with attention to socio-environmental dynamics — closely aligned with UMR LETG's multi-disciplinary model and research themes.

Broad incumbents

• IGN (Institut national de l'information géographique et forestière): French national agency for geographic and forest information — a much larger incumbent operating in similar mapping, remote sensing, and environmental monitoring territory, with broader portfolio and statutory mandate than UMR LETG.
• NASA Earth Science Division: U.S. federal program funding Earth observation science and data systems — overlaps with UMR LETG's satellite remote sensing research (e.g., CHOVE-CHUVA) and Earth observation data infrastructure at much larger scale.
• ESA (European Space Agency): European intergovernmental space agency with major Earth Observation programs (Copernicus, Sentinel) that underpin much of the satellite-based environmental research UMR LETG conducts.

Emerging players

• DINAMIS (Dispositif Institutionnel National d'Approvisionnement Mutualisé en Imagerie Satellitaire): French national infrastructure (CNES-led) providing mutualized access to satellite and drone imagery for the research community — comparable to UMR LETG's Plateforme D2T drone platform and CHOVE-CHUVA satellite workflows.
