The way, the direction) of the object, the direction angle (azimuth) between the plane of the meridian of the observation point and the vertical plane passing through this point and the observed object. It is measured from north (Surveying) or from the south (in astronomy) clockwise from up to about 36 ° °. In determining the so-called magnetic azimuth instead of geographic meridian plane take the plane of the magnetic meridian. Azimuthal, map projection, which parallels the normal grid - concentric circles, and meridians - their radii diverging from a common center parallel angles, equal to the difference in longitude.

The Earth's rotation causes day and night, determines the duration of the day. There is uneven, mainly under the influence of lunar and solar tides (tidal friction) the duration of the day increases continuously for 1-2 milliseconds per century, and due to seasonal changes (rainfall, etc.), and other tectonic processes during the year in the range 1-2 ms. The position of Earth's rotation axis, and therefore the geographic poles of the earth is changing due to precession and nutation.

Map projections, mathematical methods of image on the surface of the plane of the earth's ellipsoid or sphere. Map Projections define the relationship between the 11 coordinates of points on the surface of the earth ellipsoid and the plane.

Map Projections are distinguished: the nature of the distortion (conformal, of equal and arbitrary, including Equidistant); by type of image parallels and meridians (cylindrical, conical, azimuthal, polyconic, psevdokonicheskie, Pseudocylindrical, conditional).
