But because that approach doesn't work on the open ocean, each continent remained isolated—there was no single geodetic network to link them together. Bearings may also be forward or backward. The direction of the magnetic meridian is established at each traverse station independently. 29, 2019 (GLOBE NEWSWIRE) — Monterey Minerals Inc. Sometimes when you are doing the compass survey at places where there are materials which attract a magnetic needle of the compass, the magnetic needle fails to show the magnetic North accurately due to the attraction forces of these materials and therefore it will be deflected from true magnetic meridian. The horizontal angle made by a line with the magnetic north in the clockwise direction is the whole circle bearing of the line. The magnetic bearing of a line was found to be N 60° 30' W in 1992, when the declination was 5° 10' E. The magnetic bearing of a line is the horizontal angle which the line makes with magnetic meridian. A magnetic bearing is measured in relation to magnetic north, using the direction toward the magnetic north pole (in northeastern Canada) as a reference point. Definition of magnetic azimuth in the Definitions. The following is Importance of land surveying: It help to prepare a topographical map which shows the hills, valleys, rivers, villages, towns, forests, etc. Magnetic levitation has been studied mainly in two distinct fields of application, MAGLEV transportation and rotor bearings. Therefore BB of a line differs from FB by exactly 180o. The direction in which the compass needle points is known as Magnetic North, and the angle between Magnetic North and the True North direction is called magnetic declination or variation. After finding that line we apply the correction to the bearings of the other lines.
