Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
occasionally with a compass rose, but if so, usually on a map with north at the top and usually with north decorated more prominently than any other compass point. "Up" is a metaphor for north. The notion that north should always be "up" and east at the right was established by the Greek astronomer Ptolemy. [11]
Aid map users in estimating the coordinates of locations; Aid map users in identifying locations with known coordinates; Indicate the cardinal directions, especially on map projections in which these directions vary across the map (e.g. conic, pseudocylindrical, azimuthal) where a north arrow or compass rose would not be appropriate [5]

On nautical charts, the top of the chart is always true north, rather than magnetic north, towards which a compass points.

The light but non-white background color enables the use of white as a map symbol (the county boundary across the center). Also note the central box showing the location of a separate detail inset map. In addition to the map itself, there are various elements that are included in the map layout. The following are common elements of a map layout ...
