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) Orice lucru sau orice eveniment care poate fi văzut sau detectat printr-o anumita modalitate sau care poate fi simtit şi observat. (2) Orice lucru sau eveniment masurabil. (3) O cantitate prezentă ca o necunoscuta într-o ecuaţie şi a cărei valoare trebuie determinata. Această utilizare este gresita şi pare sa fie utilizata ca jargon de unii statisticieni.
Industry:Earth science
A pendulum taking approximately half a second to swing through the lowest point of its path twice in the same direction. A half second pendulum is about 25 cm long.
Industry:Earth science
A number telling how many units there are in a measured quantity.
Industry:Earth science
A working pendulum placed in the receiver well before use, so that it will assume the same temperature as the dummy pendulum.

(1) That point, in a coordinate system, which has defined coordinates and not coordinates determined by measurement. This point is usually given the coordinates (0,0) in a coordinate system in the plane and (0,0,0) in a coordinate system in space. In surveying, when a plane rectangular coordinate system is used, the coordinates of the origin are often given large, positive values. These values are called false easting (or false westing) and false northing (or false southing). (2) The point to which the coordinates (0,0,0,....0) are assigned, regardless of the location of that point with respect to the axes of the coordinate system. (3) The point from which coordinates of other points in the coordinate system are reckoned.
Industry:Earth science
Adjustment of a network by expressing the changes in coordinates as functions of changes in the measurements (observations).
Industry:Earth science
An equal-area map-projection mapping a rotational spheroid onto a cylinder in such a way that there is a constant ratio between the area of a region on the ellipsoid and the area of the corre-sponding region on the cylinder. When the surface is mapped onto a cylinder tangent at the equator, the map projection used is often referred to as Lambert's cylindrical equal area map projection. Among other cylindrical, equal area map projections are the modified Plate Carrée map projection (the Plate Carrée itself is not an equal area map projection), and transverse or oblique aspects of it.
Industry:Earth science
A factor used to reduce observations of celestial bodies to the barycenter of the Earth-Moon system.
Industry:Earth science
A prefix meaning the point closest to. It is usually placed before the name of the body or point the point is closest to. For example, perigee is that point, of an orbit, closest to the Earth's center of mass; perihelion is that point, of an orbit, closest to the Sun. Note that if a satellite has appreciable mass compared to the mass of the primary body, the center of mass of the two-body system is meant, e.g., lunar perigee refers to that point, in the Moon's orbit, closest to the center of mass of the Earth and Moon together.
Industry:Earth science
A municipality planned from its beginning to offer a complete range of services such as housing, recreation, schools and churches as well as a consistent and controlled balance of land use. A New Town is usually a new municipality built on previously undeveloped land close to an existing municipality. However, the term New Town in town refers to a New Town built within an existing town.
