Company Profile:
Founded in 1941, the American Congress on Surveying and Mapping (ACSM) is an international association representing the interests of professionals in surveying, mapping and communicating spatial data relating to the Earth's surface. Today, ACSM's members include more than 7,000 surveyors, ...
One of the two coordinates in a Universal Transverse Mercator Grid System.

(1) The two sets of corners along a standard parallel, i.e., the standard township, section, and quarter section corners placed at regular intervals of measurement. This is the standard meaning. (2) The closing corners established on the line at the points of intersection of the guide meridians, range, and section lines of the surveys brought in from the south. This is a less common meaning.
Industry:Earth science
(1) The configuration taken by the Sun, the Earth, a second planet when the apparent geocentric (celestial) longitude of Sun and second planet are the same. (2) The phenomenon in which two bodies have the same apparent celestial longitude or right ascension as viewed from a third body. Conjunctions are, however, usually tabulated as geocentric phenomena.

Industry:Earth science
A square protractor having graduations on two adjacent edges, with the center at one corner, and ruled with a square grid having intervals of one centimeter or other linear unit. It has a movable arm turning with the center as pivot and graduated in the same units and at the same scale as the ruled grid. In using the protractor, the arm is set to a given angle, azimuth or bearing, and the length of a line is marked on the arm; inspection of the grid at this point will give the components of that length along the axes marked by the edges of the protractor.

(1) The vertical rise, expressed in inches, between the edge and the center line of the base or surface. (2) The rate of rise between the edge and the center line of the base or surface. (3) The inside top of a sewer.
Industry:Earth science
Any number which is accepted by physicists as being characteristic of a measurable or calculable quantity; a constant quantity or value having physical significance. Also referred to as a fundamental constant, although this is a misnomer. Those physical constants occurring frequently in the equations of physics and from which all other physical constants can be derived are called fundamental physical constants. Physical constants of geodetic importance are given in the Appendix.
