The G-pel method for determining the degree of greening of the area using the city of Penza as an example

Abstract

The possibility of using publicly available software and a satellite map to determine the extent of vegetation coverage has been studied. It is suggested to apply an express method for determining the proportion of a green area from the total area with an average error for P=0.95 12.4±3.25% using the GIMP software (G-pel method). To assess the reliability of the method, similar results obtained by the overlay grid technique were compared with those of determining the forest cover of the Volga region cities using neural networks with satellite images made by a group of Canopus-V satellites. The deviation of the G-pel method results from the results of determining the forest cover of Volga region cities using neural networks averaged 11%. The difference between the results of the overlay grid technique and the G-pel method turned out to be unreliable.
