WebScore: 4.6/5 (17 votes) . The Orthometric Height or Geodetic Height is the vertical distance from a location on the Earth's Surface distance to the geoid (blue surface in the illustration). Because the earth geoid is set a the level of the average sea level it is often called the elevation at Mean Sea Level (MSL). Webgeodetic measurement Any measurement concerned with the shape figure of the Earth, often involving the geoid. Source for information on geodetic measurement: A …
WebGeodesy is the science of measuring the earth's size, shape, orientation in space, and gravity—elements that are constantly changing. This field of study dates back to ancient … Geopositioning, or simply positioning, is the determination of the location, as defined by a set of geodetic coordinates, of a point on land, at sea, or in space within a coordinate system (point positioning) or relative to another point (relative positioning). One computes the position of a point in space from measurements linking terrestrial or extraterrestrial points of known location ("known points") with terrestrial ones of unknown location ("unknown points"). The computation may invo…
A geodetic datum or geodetic system (also: geodetic reference datum, geodetic reference system, or geodetic reference frame) is a global datum reference or reference frame for precisely representing the position of locations on Earth or other planetary bodies by means of geodetic coordinates. … See more The spherical nature of Earth was known by the ancient Greeks, who also developed the concepts of latitude and longitude, and the first astronomical methods for measuring them. These methods, … See more In geodetic coordinates, Earth's surface is approximated by an ellipsoid, and locations near the surface are described in terms of geodetic latitude ($${\displaystyle \phi }$$), longitude ($${\displaystyle \lambda }$$), and ellipsoidal height ($${\displaystyle h}$$). See more The Earth's tectonic plates move relative to one another in different directions at speeds on the order of 50 to 100 mm (2.0 to 3.9 in) per year. Therefore, locations on different plates are in motion relative to one another. For example, the longitudinal difference between … See more Horizontal datum The horizontal datum is the model used to measure positions on Earth. A specific point can have substantially different coordinates, depending on the datum used to make the measurement. There are hundreds of local … See more The difference in co-ordinates between datums is commonly referred to as datum shift. The datum shift between two particular datums can vary from one place to another within … See more A geodetic reference datum is a known and constant surface which is used to describe the location of unknown points on Earth.
