The OSR site and its members are involved in

  1. The Sentinel 2 agriculture project :

    see :

    The Sentinel-2 for Agriculture (Sen2-Agri) project has been launched by ESA, as a major contribution to the R&D component of the GEOGLAM initiative and to the JECAM network activities. The project will demonstrate the benefit of the Sentinel-2 mission for the agriculture domain across a range of crops and agricultural practices. The intention is to provide the international user community with validated algorithms to derive Earth Observation products relevant for crop monitoring (in particular mapping of the crop fields). The project is ending in July 2017.

  2. The sites are involved in several collaborative projects such as CiCC ( and CESEC financed by the French agency ADEME, MAISEO ( and REGARD (
  3. The sites are also involved in several networks such as Fluxnet ( and ICOS ( The ICOS network will be running for the next 20 years.
  4. OSR is part of the French THEIA initiative ( The Theia Land Data Centre is a French national inter-agency organization designed to foster the use of images issued from the space observation of land surfaces. Theia is offering scientific communities and public policy actors a broad range of images at different scales, methods and services. They partners are potentially involved in "thematic" and / or "regional" expertise centers. The Scientific Expertise Centres are laboratories or groups of national laboratories leading research and developing innovative processes to use space data for “land surfaces” issues. The OSR is involved in 12 of them (see The Regional CES's objectives are 1) to unite and coordinate users (scientists and public stakeholders) at regional level, and 2) to participate in community training efforts, particularly concerning added-value products developed by the thematic CES’s. The OSR is indentified in THEIA as the Midi-Pyrénées CES.
  5. A scientific and technical network on sunflower has been layed out from 2012 to 2017 in Toulouse (named "UMT Tournesol"). Remote sensing research and development is one of the major contributions of CESBIO to this UMT. A 3-year project has begun in 2014 on "sunflower yield and quality prevision" involving also agricultural cooperatives. Several campaigns have been performed in 2014 by Cesbio, Cetiom and INRA (measurements of  GAI, biomass and yield). In this frame, we tested different approaches to calibrate relationships between remotely sensed and in situ GAI (calibration of BVnet...). Field data will be used to calibrate models like SAFYE or SUNFLO that simulated among other things biomass and yield.
  6. SENSAGRI (Sentinels Synergy for Agriculture) project ( This project was financed in 2016 in response of the EO Work programme ‘EO-3-2016: Evaluation of Copernicus Services’. We answered that call jointly with Universitat de València (UVEG), Consiglio Nazionale delle Ricerche - Istituto di Studi sui Sistemi Intelligenti per l’Automazione (CNR-ISSIA), Consiglio per la Ricerca in Agricoltura e l'Analisi dell'Economia Agraria (CREA), Instituto Tecnológico Agrario de Castilla y León (ITACyL), National Research Institute - Institute of Plant Protection (IPP). It aims to exploit the unprecedented capacity of S1 and S2 to develop an innovative portfolio of prototypes agricultural monitoring services : three prototype services capable of near real time operations: (1) surface soil moisture (SSM), (2) green and brown leaf area index (LAI) and (3) crop type mapping. These prototypes shall provide a baseline for advanced services that can boost the competitiveness of the European agro-industrial sector. SENSAGRI proposes four advanced proof-of-concept services: (i) yield/biomass, (ii) tillage change, (iii) irrigation and (iv) advanced crop maps. The algorithms will be developed and validated in four European agricultural test areas in Spain, France, Italy and Poland, which are representative of the European crop diversity, and their usefulness demonstrated in at least two non-European countries. The prototypes should also be tested in Morocco and South Africa.
