Canopy cover mapping
Canopy cover is a necessary criterion for calculating the area of the
leaf surface per 1 ha of forest covered area. It is determined through
the area of canopy per 1 ha of forest. The initial basis for
calculations was a mosaic basemap of space images of ArcGIS Imagery,
spatial resolution of which allows us to visually detect the presence of
vegetation and forest areas selected on the Sentinel image. Canopy cover
mapping was performed with the use of licensed software package ArcGIS
10.4. In order to estimate canopy cover, the extent of the studied area
was divided into grid squares of 100m*100m. Then, overlay operations
were performed for each square using GIS-technologies to calculate the
area occupied by vegetation. The result of measurements obtained by the
grid square method is shown in the figure (Fig. 7).
