The angle between the two--known as the declination--varies depending on your location. It also gradually changes over time as the Earth's tectonic plates shift.
Because declination changes over time, newer maps will have more accurate figures. There should be an angle and a direction—for example, 8 degrees east. Working from an older map?
The space between true North and what compasses recognize as geomagnetic North is called the angle of declination. As the two locations move closer, that angle gets smaller.
As if this wasn't enough of a nuisance for navigators, the Earth's magnetic field drifts, causing the angle of declination to change over time. In fact, it drifts about one-fifth of a degree a ...
Angular declination (also known as 'height in the field') is the angle between a visual target, typically one situated on the ground, and an observer's eye level, which generally coincides with ...
It’s time to go analog with your navigation tools. Using a map and compass is one of the most reliable foundational skills of the wilderness.
