geodesic line, geodetic line
1. The line of shortest distance between any two points on a mathematically defined surface.
2. Specifically, on the surface of the earth, a line of double curvature; which usually lies between the two normal section lines determined by the two points.

geodetic astronomy
The branch of geodesy (study of the size and shape of the earth) which utilizes astronomical observations to extract geodetic information (precise measurement of the earth's surface or of points on its surface).
This entry is located in the following unit:
geodetic control
A system of horizontal or vertical control stations which have been established and adjusted by geodetic methods and in which the shape and size of the earth (or the geoid) have been considered in computing positions.
This entry is located in the following unit:
geodetic coordinates
1. A reference to a location on earth defined by its latitude, longitude and elevation.
2. The quantities of latitude and longitude which define the position of a point on the surface of the earth with respect to the reference spheroid.
3. The latitude and longitude of a point on the earth's surface determined from the geodetic vertical (normal to the specified spheroid).
This entry is located in the following unit:
geodetic datum
1. A reference surface forming the basis for the computation of horizontal-control surveys in which the curvature of the earth is considered.
2. A datum consisting of five quantities: the latitude and longitude of an initial point, the azimuth of a line from this point, and two constants necessary to define the terrestrial spheroid.

Horizontal datum is used for describing a point on the earth's surface, in latitude and longitude or another coordinate system. Vertical datum measures elevations or depths.

geodetic gravimetry
The science or technique of measuring gravitational acceleration for the purpose of determining the size and shape of the earth.

geodetic height
A geometric surface or a solid figure shaped like an oval.

Any section through an ellipsoid is either an ellipse (a two-dimensional shape like a stretched circle with slightly longer flatter sides) or a circle.

This entry is located in the following unit:
geodetic leveling
Spirit leveling (device or level for determining a true horizontal or vertical reference point) of a high order of accuracy, usually extended over large areas, to furnish accurate vertical control in the vertical dimension for all surveying and mapping operations.

The leveling follows the geoid and its associated irregular level surfaces rather than any mathematically determined spheroid or ellipsoid and associated regular level surfaces.

geodetic position
In cartography or maps, the position of a point on the surface of the earth expressed in terms of geodetic latitude and geodetic longitude.

geodetic precession
1. In physics, the movement of the axis of a spinning gyro in orbit around a heavenly body which is caused by the curvature of space.
2. The curvature of spacetime, predicted by general relativity, on a vector carried along with an orbiting body.

geodetic satellite
1. An artificial earth satellite used to obtain data for geodetic triangulation calculations.
2. In space technology, an artificial satellite designed or launched especially for gathering data regarding the size, shape, and mass distribution (gravity) of the earth as well as the precise positions of points or areas on its surface.

geodetic survey (s) (noun), geodetic surveys (pl)
An examination of a large area of land in which corrections are made to account for the curvature of the earth: A geodetic survey involves research in which the form and the size of this planet are considered and for which corrections are made.
