DoodsonHarmonics2GriddedAmplitudeAndPhase

This program reads a inputfileDoodsonHarmonics and evaluates a single tidal constituent selected by dooddson (Doodson number or Darwin´s name, e.g. 255.555 or M2). This program computes the amplitude and phase from the cos and sin coefficients on a given grid. The type of functional (e.g gravity anomalies or geoid heights) can be choosen with kernel. 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. To visualize the results use PlotMap.
