geo-, ge- +
(Greek: earth, land, soil; world; Gaia (Greek), Gaea (Latin), "earth goddess")
2. A plant having perennating organs (surviving from year to year) or renewal buds below the surface of the soil.
2. A hollow, roughly spherical rock mass containing a cavity, lined or filled with crystals lining the inside walls, that have grown unimpeded and so are frequently perfectly formed.
3. Etymology: from French géode; from Latin geodes; from Greek geodes, "earthy, earth-like"; from ge-, "earth".
Visible structures like mushrooms are reproductive structures produced by the mycelium or the mass of fibers formed by certain bacteria.
2. The shortest line between two points on a mathematically defined surface (as a straight line on a plane or an arc of a great circle on a sphere).
3. Etymology: "surveying", from Modern Latin geodaesia, from Greek geodaisia, "division of the earth" (from ge, "earth" + daiein, "divide").
2. A strong prefabricated enclosure constructed of lightweight bars forming a grid of polygons, with no internal supports.
The dome is energy efficient because it requires less building material and has less surface area, because heat loss due to wind turbulence is decreased, and because its shape minimizes air leakage.
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.
2. The branch of science that deals with the precise measurement of the size and shape of the earth, the mapping of points on its surface, and the study of its gravitational field.
3. A subdivision of geophysics which includes the determination of the size and shape of the earth, the earth's gravitational field, and the location of points fixed to the earth's crust in an earth-referred coordinate system.
4. The determination of the geometry of the earth's surface (both solid and liquid), including the time variability of this geometry.
Determination of the earth's orientation is essential because a number of measurements of geometric quantities involve observations of extraterrestrial objects (artificial satellites, radio stars, etc.). These measurements can not be interpreted without knowledge of the earth's orientation.
Relating to the geometry of curved surfaces.
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).
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.
