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, ...
(1) A monument marking a point, on an irregular boundary line, reservation line, boundary of a private claim, or a re established, non riparian meander line, at which a change in azimuth occurs.
(2) A stake driven into the ground at a point on a traverse, to indicate a change in direction of the traverse at that point.
(3) A point, in a survey, at which the alinement or boundary deflects from its previous course.
(4) A marker placed to indicate a point at which there is a change in the direction of a surveyed line.

(1) The highest point of something, as of a cone or triangle, or the greatest latitude (vertex) of a great circle.
Industry:Earth science
The legal and demonstrative processing of casework to assure full compliance with the public-land laws and regulations and to determine rights.
Industry:Earth science
The distance and direction between complementary image points in a stereoscopic pair of photographs.
Industry:Earth science
A method of traversing by plane table, in which the alidade is first placed on a selected line on the map which corresponds to an established line on the ground. The table is then rotated until the line of sight through the alidade coincides with the corresponding line on the ground.
Industry:Earth science
The movement of a fluid, or of a scalar quantity that is considered to move with the fluid. In particular, in oceanography, the term refers to the horizontal or vertical flow of sea water, e.g., a current. In meteorology, it refers either to the predominantly horizontal movement of large masses of the atmosphere or to the transport of an atmospheric property solely by movement of the atmosphere.
Industry:Earth science
A beach whose sand is removed by storm waves but is quickly restored by longshore currents.
Industry:Earth science
An adjusted value of an angle. An adjusted angle may be derived either from an observed angle or from a concluded angle.
Industry:Earth science
A plat showing only those details essential for identifying the legal subdivisions shown on it. A base plat may also show such cultural and topographic features as are thought desirable. However, it is now usual to show culture, topography, etc. , by transparent overlays to the base plat.
Industry:Earth science
Corrections are applied to the measured quantities (or to the calculated components of these) according to the surveyor's analysis of conditions that prevailed along the traverse. i.e., the corrections needed to eliminate the misclosure are weighted according to the surveyor's judgement and not according to fixed rules.
