It is of major importance to use operationally all Earth Observation data for Agriculture and Environmental (A&D) purpose with consideration of both spatial and temporal evolution.Earth observation provides big data (in terms of volume, variety, and velocity) that is valuable for agriculture activities. This Big Data management is the aim of the discipline of geomatics that combines tools and methods for acquiring, representing, analyzing and integrating multisource geographic data (Remote Sensing RS, Geographic Information System GIS, Spatial Analysis AS…) that require improvements in Tunisia. The main objective of GEOMAG is to develop the adaptation capacities of Tunisia's higher and vocational education system in the field of A&D by taking into account Geomatics.GEOMAG aims to establish:- The basics useful for acquiring skills in Geomatics and spatial data quality control, through design, experimentation, provision - including web learning (e-learning) - of initial training courses (FI ) and professional (FP) ones adapted to the various specialties associated with Geomatics applied to A&D: GIS, AS, geodesy, Big data ... The pedagogical engineering will be preceded by a prior 'study-validation' of the Tunisian EES and professional needs in the matter.- The capacities of the academic institutions for the operational implementation of Geomatics: for the FI at the licence, engineering, Masters and PhD levels, for the FP with the managers (sensitization) and professionals (training-action) of the sector, for research and technology transfer to teacher-researchers and other 'professionals of the academic world, to be specifically trained.- The networking of TN partners and A&D TN associated partners, with the EU partners, by creating an open and evolving platform of (inter)national expertise and sharing. GEOMAG contributes to the improvement of the management and the valorization of the natural resources and the agricultural management activities in Tunisia.
