A circle graduated in DEGREES clockwise from 0° (north) to 360° printed on a CHART for use as a PROTRACTOR. Compass roses are also placed ... more
A circle graduated in DEGREES clockwise from 0° (north) to 360° printed on a CHART for use as a PROTRACTOR. Compass roses are also placed at other convenient locations to facilitate measurements of directions. They may be oriented to the TRUE or the MAGNETIC NORTH.
953
compensate
(v.t.). To counteract an ERROR, as in an instrument; to counterbalance.
954
compensating coils
The coils placed near a MAGNETIC COMPASS to neutralize the effect of the vessel's degaussing system on the COMPASS.
955
compensation depth
See DEPTH.
956
compensation of magnetic compass

The process of neutralizing or reducing to a minimum the magnetic effects the vessel itself exerts on a MAGNETIC COMPASS. It is based on the principle that the magnetic effect of the iron and steel of the vessel can be counterbalanced by means of MAGNETS and SOFT IRON placed near the COMPASS. Also called compass adjustment, compass compensation, or magnetic compensation.
957
compensator: magnetic

A MAGNET, piece of SOFT IRON such as a sphere or iron bar, placed in a BINNACLE or in vicinity of a MAGNETIC COMPASS for reducing MAGNETIC DEVIATION to a minimum. Also called compass corrector or corrector magnet. See FLINDERS BAR, HEELING MAGNET, QUADRANTAL CORRECTORS.

In CARTOGRAPHY, the selection, assembly, and graphic presentation of all relevant information required for the preparation of a MAP or CHART, or a NEW EDITION or part thereof. Such information may be derived from other MAPS or CHARTS, AERIAL PHOTOGRAPHS, SURVEYS, new DATA, and other sources. In PHOTOGRAMMETRY, the production of a MAP (or portion of a MAP) from AERIAL PHOTOGRAPHS and geodetic control data, by means of photogrammetric instruments. Sometimes called stereo compilation.
