The article presents a model for assessing the information capabilities of multi-, hyperspectral satellite systems for Earth remote sensing in solving forest monitoring problems. The information capabilities of satellite system for Earth remote sensing means the ability to complete assigned tasks in time and quality. Assessment of information capabilities is divided into two parts. The first part is an assessment of the operational capabilities of the satellite system, that is, an expected time to complete the task. The second part is an assessment of solving the problems quality. Assessing of the information capabilities of satellite systems for Earth remote sensing allows to determine the appropriateness of including the task of monitoring territories (for example, forest monitoring) in the flight task for the satellite system, to develop measures to improve information capability in solving the tasks. The article also provides informational capability assessment obtained by the proposed method for the hyperspectral satellite system by NPO «Lepton» and Moscow Institute of Physics and Technology in solving the problem of classifying the species composition of deciduous and coniferous forest on a given territory. Such assessment is valid for similar satellite systems for Earth remote sensing when solving similar problems.
