Methods and information tools for analyzing remote sensing data to detect changes in vegetation caused by industrial waste and dumps

Vega-Science Services for Monitoring the Impact of Technogenic Waste and Dumps Sources on Environment

“…The degree and severity of TWDS impact substantially depends on the type of vegetation cover and on the weather and climatic conditions in which this effect occurs (see (Savorskiy et al, 2019) and references therein). In particular, for forest cover, TWDS impact depends on the biological characteristics of the main tree species that grow on the observer site, their age status and quality class.…”

“…To identify disturbance of the forest cover associated with problems of respiration and water metabolism of plants, it is advisable to apply the methodological approach described in (Gornyy et al, 2010(Gornyy et al, , 2011(Gornyy et al, , 2013(Gornyy et al, , 2019. This method is based on results of (Jorgensen, Svirezhev, 2004) showed that the rate of evaporation of moisture from the surface of an ecosystem is a measure of the response of an ecological system to external influences.…”

“…Therefore, the detection of disturbance caused by TWDS, involves the use of such methods of monitoring the state of vegetation, which are robust to changes in temperature and humidity conditions. It is necessary in order to ensure long-term monitoring of control areas of forest cover for 10-20 years for at least one of the types of disturbance described in the paper (Savorskiy et al, 2019), which influence plants 1) growth, 2) development, 3) photosynthesis, 4) respiration, 5) water exchange. The need to detect the influence of TWDS at significantly different temperature and humidity observation conditions form the following number of requirements for the list of the source and auxiliary data that ensure stable operation of the algorithms for detecting forest canopy disturbance caused by TWDS: 1) TWDS description database (coordinates, type, formation period, polluting factor), 2) the database of the forest plots (allotments) having close characteristics and taxonomy (main breeds, stock, quality class) to the ones in the areas of TWDS, 3) the database for search and selection of forest areas (allotments) having similar weather and climatic characteristics (temperature, humidity, soil moisture, wind speed and direction) to the ones in the areas with TWDS impact, 4) medium and high spatial resolution historical satellite observations data archive for selected control and reference forest areas, 5) medium and high spatial resolution real time satellite observations data archive for selected forest areas.…”

“…The development of methods for monitoring the state of vegetation, which reveals environment changes due to impact of TWDS is the main goal of the work. The paper (Savorskiy et al, 2019) gives an analytical review describing the mechanisms of influence of typical harmful TWDS on the vegetation covers and proposes methods and approaches that allow identifying changes in the vegetation cover caused by the influence of TWDS. That work results in the statement of proposals for making up the comprehensive list of parameters for forest state control based on satellite observations, including the use of spectral indices for these purposes.…”

“…The obtained results allowed substantiating the use of the funds and resources of IKI-Monitoring (Loupian et al, 2019) as a platform for the development of tools to control the TWDS the impact. The presented paper contains the results of the paper (Savorskiy et al, 2019) continuation in developing information services necessary for implementation remote sensing control of TWDS impact on forestland environment. Namely, the main objective of the work is the creation and the upgrade of the information tools of the VEGA-Science system (http://sci-vega.ru/eng/) to be able to analyse of the changes in state of the vegetation cover for monitoring TWDS impact.…”
