Abstract
The paper deals with opportunities of remote probing as a method to assess the environmental condition of hard-to-reach areas. The dynamics of changing the condition of the vegetation cover of anthropogenically disturbed areas of the Tomsk region under conditions of the negative impact of oil recovery was investigated using freely distributed satellite MODIS images of medium spatial resolution. Vegetation cover condition was assessed according to the value of the normalized difference vegetation index (NDVI). Condition dynamics for vegetation cover in the vegetation season was analysed over the 9-year period from 2010 to 2018. The work stepwise stated the processing algorithm of satellite data using geographic information system ArcGis 10.2.2. Analysis was performed for NDVI values of the background territory of the Oglatsky wildlife reserve and five territories of oil and gas fields in the Tomsk region. The latter include Luginets, Olenie, Lomovoye, Katylginsky, and West Katylginsky fields. As determined, the trend of changing index values for all investigated areas is single-type: high and minimum magnitudes in 2016 and 2012, respectively. As demonstrated by the analysis of the dynamics of changing average NDVI values during vegetation, there are improved but significantly reduced NDVI magnitudes in all investigated areas from 2012 to 2016 and 2016 to 2018, respectively.
