Gravityfield2AbsoluteGravity
This program computes the absolute value of gravity $\left\lVert{\M g}\right\rVert$ of a gravityfield on a given grid. The result is multiplicated with factor. To get the full gravity vector in a terrestrial frame add the centrifugal part, see gravityfield:tides:centrifugal.
The values will be saved together with points expressed as ellipsoidal coordinates (longitude, latitude, height) based on a reference ellipsoid with parameters R and inverseFlattening.
It is intended to compute gravity anomalies from absolute gravity observations. To visualize the results use PlotMap.
