The impact of hazardous waste on people and the environment from agricultural, industrial, military and mining activities form one of the most significant global environmental challenges. These wastes often include heavy metals, acid precipitates (sulfur oxide solutions), hydrocarbons, and other organic chemicals. Environmental impact of such technogenic waste and dumps sources (TWDS) is widely reflected in vegetation cover changes, which can be easily detected by satellite instruments. But application of satellite data for TWDS monitoring requires appropriate information tools. At presented work, the authors conducted the development of the design and implementation of these tools within frames VEGA-Science services (http://sci-vega.ru/eng/) in order to provide analysis of longterm variability of the vegetation cover state caused by the influence of TWDS. The result of the work was included in automated system for remote monitoring of vegetation cover (SRMV) of VEGA-Science system.
