A WTG will be visible if it is visible from any part of the receiver window. The ZVI calculation is based on the following assumptions: Height contours used: Height Contours: Pyhtää kk.wpo (1) Obstacles used in calculation Eye height: 1,5 m Scale 1:40 000 Grid resolution: 10,0 m New WTG Finish GK KKJ (3 deg)-kkj (FI 1992 <±5m) Zone: 3 WTG type Shadow data East North Z Row data/description Valid Manufact.
