1) Accurate navigation: Magnetic declination is the angle between magnetic north and true north in a specific location. By knowing the calculated magnetic declination, a person can adjust their compass readings to ensure accurate navigation. This is especially important when using a map on a school excursion, as it helps the person determine the correct direction they need to go in order to reach their desired destination.
2) Orienting the map correctly: Maps are typically oriented to true north. However, magnetic declination causes a discrepancy between magnetic north and true north. By knowing the calculated magnetic declination, a person can adjust the orientation of their map accordingly. This allows them to align the map with the actual compass readings, ensuring that they are able to accurately identify landmarks, interpret symbols, and plan their route on the map during the school excursion.
