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, ...
The larger bodies revolving about the Sun in nearly circular orbits. The known principal planets, in the order of their distances from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
Industry:Earth science
Any pendulum not having its entire mass concentrated at one point. Any real pendulum is a compound pendulum. It can be considered to be made up of a large number of material particles, each at a different distance from the center of suspension and each constituting the bob of a simple pendulum. The period of oscillation of the compound pendulum is the resultant of the periods of the simple pendulums composing it.
Industry:Earth science
A municipal law, comparable to a statute on State and Federal levels.
Industry:Earth science
Impose one or more images by a process of step-and-repeat exposing to predetermined positions on a pressplate or photographic negative by means of a machine built for that purpose.
Industry:Earth science
An orbital perturbation caused by gravitational forces. Among the causes are tides, non-central sources of gravitational force and relativistic changes of mass, time and distance.
Industry:Earth science
A container for photographic plates or rolled photographic film, attached to the body of a camera in such a way that plates or film can be moved directly from the magazine into the camera's chamber and into the focal plane of the camera. Small magazines are also called cassettes or, if they are cylindrical, cartridges. Magazines containing photographic plates are also called plate holders. Magazines attached to aerial cameras have a mechanism for automati-cally advancing the photographic material between exposures.
Industry:Earth science
Photogrammetry applied to determining the horizontal coordinates of points on the Earth' surface or on the surface of the Moon or other celestial body. I.e., photogrammetry applied to determining the coordinates in a coordinate system on the surface of the body, so that each point on the surface has only two coordinates.
Industry:Earth science
The line on an ellipsoid, or the corresponding line of a graticule, in which a suitably defined plane perpendicular to the plane of the fictitious equator intersects the ellipsoid. If the chosen plane is also a reference plane, the resulting fictitious meridian is called the prime fictitious meridian.
Industry:Earth science
Two or more overlapping photo-graphs having different camera stations, i.e., taken from different points.
