We propose the technique of environmental assessment based on the landscape system method and remote sensing data. The landscape formations are considered as complex systems consisting of certain landscape types taking into account their priority in the natural-technical systems and determined as the results of remote sensing data interpretation. We use methods of contrast-analogue and indicator interpretation at visual and computer image processing. The integral approach to the landscape classification is suggested; the landscape complexes are recognized by the grade of anthropogenic and technical factors as well as the change ratio of components and their spectral differences in the visible and IR bands. The developed classification takes into consideration the groups of natural, modificated, anthropogenic and technical landscapes those are divided also by environmental suitability. To assess the environmental state of mining systems, the seven standard samples of environmental situations were developed. The natural-based and technical systems are considered as an hierarchic community of the landscape complexes.
