declination maps

Declination maps, also known as compass or variation maps, show the difference between true north (geographic north) and magnetic north (the direction a compass needle points). This difference, called declination, varies across locations and over time. These maps help navigators and hikers adjust their compass readings to accurately find directions, ensuring they travel in the intended bearing. Essentially, declination maps guide users on how to correct compass readings based on where they are, improving navigation accuracy whether exploring the outdoors or conducting precise surveying.
