The project on multilevel system of Earth operational hyperspectral monitoring is oriented towards development of regional system of operational hyperspectral monitoring of physicochemical conditions of natural and anthropogenic objects based on data obtained with hyperspectral sensors used in space, aviation and ground facilities in the interest of regional state authority and local government as well as in the interests of enterprises having different form of property to solve a wide range of socioeconomic and scientific tasks.
Detection of chemical composition Database of spectral signatures LevelFunction Space Global observation of Earth surface using three type of equipments Aviation Operative high-resolution hyperspectral imaging. Synchronous under spacecraft imaging for calibration and validation remote sensing data from Resurs-P spacecraft Ground Probe fence of soil and water, their analyzing, forming and updating database of etalons of relations «spectral coefficient of surface reflection – chemical composition»
Development and examination plane- laboratory equipped hyperspectral sensor (0,4 – 2,5 µm) and high-precision navigation equipment, attestation and certification it. Development of hyperspectral data found. Development of system of stationary and mobile physical and chemical laboratories. Development of software of thematic processing Information, obtained from the hyperspectral monitoring system. Organization business structures for dissemination of remote sensing information.
