geoid उदाहरण वाक्य

उदाहरण वाक्य

1. The reference surface for orthometric heights is the geoid, an equipotential surface approximating mean sea level.
2. The deviations of the geoid from the first order spheroid are on the order of ?100m.
3. Dynamic topography is the reason why the geoid is high over regions of low-density mantle.
4. Ocean surface topography is specifically the distance between the height of the ocean surface from the geoid.
5. Sea level can also be measured by satellites using radar altimetry, contributing to a more accurate geoid.
6. Currently, WGS 84 uses the EGM96 ( Earth Gravitational Model 1996 ) geoid, revised in 2004.
7. It is then possible to compute the geoid height by subtracting the measured altitude from the ellipsoidal height.
8. Spatial variations in gravity exert influence on the ocean surface and thereby cause spatial structure in the geoid.
9. They are used in gravity surveys over large areas for establishing the figure of the geoid over these areas.
10. This terminology is also used for such approximately spheroidal astronomical bodies as the planet Earth ( see geoid ).
