Abstract (English):
The article considers the research of vegetation phytodiversity in the Voronezh upland oak grove, both geobotanical methods and specialized Internet resources were used, in particular the Google Earth application. The boundaries of the parcels were identified by field methods, taking into account the distance to permanent landmarks (poles marking the boundaries of the sample plot), as well as with reference to individual trees and GPS coordinates, where this was possible. Subsequently, the boundaries of the parcels and the calculation of their area were carried out using the Google Earth application. Using built-in tools, the boundaries of the parcel contours were applied and their areas in hectares were calculated. The resolution of modern satellite images allows for fairly accurate determination of the boundaries of tree crowns, especially in the autumn. Images taken in the summer and, especially, in the winter, cannot be used, since they make it impossible to take into account the contours of the crowns. The presented data allow us to determine the ratio of the area occupied by edificators and coedificators of the tree layer, as well as to link these data with the floristic composition. The application of parcel boundaries using web resources and subsequent determination of their area seems to be a very promising method for digitalizing data on the study of phytodiversity of forest communities.
