METHOD FOR CLASSIFYING VEGETATION AND GROUND COVER DISTURBANCES BASED ON THE DYNAMICS OF THE THERMAL BACKGROUND ANOMALY IN THE SUMMER PERIOD ACCORDING TO SATELLITE MEASUREMENTS IN THE INFRARED RANGE Russian patent published in 2023 - IPC G01J5/60 

FIELD: environmental monitoring.

SUBSTANCE: invention relates to environmental monitoring and thematic remote sensing, and in particular to a method for classifying the disturbance of vegetation and ground cover in areas after natural, anthropogenic or man-made impacts. In a method for classifying vegetation and ground cover disturbance based on the dynamics of the thermal background anomaly in summer, using satellite measurements in the infrared range, using satellite imagery in the infrared range of 10.0–13.0 μm with a resolution of at least 1000 m, the average values of the temperature of the underlying surface are determined areas subjected to natural or technogenic destructive effects, on the basis of which the initial value of the relative surface temperature anomaly ΔT_rel/in in relation to the background values (T_bg) is then calculated as (ΔT_rel/in = (T – T_bg)/ T_bg), the rate of decrease/leveling of the relative anomaly (V_ch) in the first 1–7 years as the slope on the curve of change ΔT_rel from time, the characteristic period of stabilization (t_ch), i.e. the time during which the anomaly leveling rate tends to zero the residual level of the relative anomaly is estimated when the recovery process is stabilized ΔT_rel/res), according to the totality of these parameters, the disturbance of vegetation and the ground cover of a particular area is classified. Additionally, the problem of predicting the listed parameters of the restoration process for areas with an established type of destructive impact is solved in the reverse way.

EFFECT: invention provides the possibility of automatic monitoring of the state and dynamics of disturbed territories for the purposes of long-term environmental control.
