On the contrary, the edge-based methods, such as the Local Directional Pattern (LDP) [7], Local Directional Number Pattern (LDN) [4], Local Principal Texture Pattern (LPTP) [8] and Positional Ternary Pattern (PTP) [9] utilize the local edge directional information to represent local texture.

In order to identify EML propagation limits and adjustment areas in a specific locality, it is necessary to appropriately select the main parameters of antenna spatial distribution: height of the antenna's geometric centre, direction of the most intensive radiation (azimuth) and the required downtilting of directional pattern on the vertical and horizontal plane.
