CARA MEMBACA NILAI VARIASI PADA ECDIS DAN PETA ‼️

Variation on a ship is the angle formed between True North and Magnetic North at a specific coordinate point. This occurs because the Earth's magnetic poles do not perfectly align with the Earth's true (geographic) poles, which causes magnetic compasses to deviate. How to Read Variation on a Nautical Chart Every nautical chart has a compass circle called a Compass Rose. The outer circle indicates True North, while the inner circle indicates Magnetic North. The writing on the compass rose indicates the magnitude of the variation angle and the direction of the deviation.
