Other grid lines establish a local "grid north", which will differ from true north by a small amount. The amount of this deviation, which is indicated on USGS topographic maps, is typically much less than the magnetic declination (between true north and magnetic north), and is small enough that it can be disregarded in most land navigation ...
The peculiarity of 'lines' (streets) naming in this grid is that are each side of street has its own number, so one 'line' is a side of a street, not the whole street. The numbering is latently zero-based, however the supposed "zero line" has its proper name Kadetskaya liniya, while the opposite side of this street is called the '1-st Line ...
A typical map with grid lines. The Ordnance Survey National Grid (United Kingdom) and other national grid systems use similar approaches. In Ordnance Survey maps, each Easting and Northing grid line is given a two-digit code, based on the British national grid reference system with an origin point just off the southwest coast of the United ...

The convergence angle γ at a point on the projection is defined by the angle measured from the projected meridian, which defines true north, to a grid line of constant x, defining grid north. Therefore, γ is positive in the quadrant north of the equator and east of the central meridian and also in the quadrant south of the equator and west of ...
The principal lines are oriented to the magnetic north pole. [12] Thus the grid lines varied slightly for charts produced in different eras, due to the natural changes of the Earth's magnetic declination. [12] These lines are similar to the compass rose displayed on later maps and charts. "All portolan charts have wind roses, though not ...
Grid-based transformations directly convert map coordinates from one (map-projection, geodetic datum) pair to map coordinates of another (map-projection, geodetic datum) pair. An example is the NADCON method for transforming from the North American Datum (NAD) 1927 to the NAD 1983 datum. [ 26 ]
