WebNote: North is just a reference direction. By itself, it doesn't have an angular value. (You and @iant have already hit on that concept.) The difference between two Norths does have an angular value – it is the correction you refer to. A bearing (or azimuth) is a clockwise angle from (some) North to some direction of interest.

That place is called the True North Pole. True south is the direction opposite to the true north. North per se is one of the cardinal directions, a system of naming orientations on the Earth. There are multiple ways of determining north in different contexts. people in society sqaGeodetic coordinates are a type of curvilinear orthogonal coordinate system used in geodesy based on a reference ellipsoid.
