MENELAOS^NT addresses societal key challenges, e.g., sustainable agriculture and forestry, bioeconomy, environmental changes, resource efficiency, as well as protecting freedom and security of the European society. MENELAOS^NT applies Novel TechnologiesNT to realize multimodal – multi sensor data fusion to optimally combine the information “partitions”, delivered by different sensors (in-situ/remote, optical/non optical) on different scales, with different resolutions and with different reliability. Traditional remote observation, as well as local (in-situ based) approaches have demonstrated to be insufficient to cope with the ample but very tailored information need of the decision-making bodies.
