ELGRAM
Ellipsoidal Gravity Model Manipulator

Source code (fortran 77) for evaluating at sparse points or an a grid the following functionals

  • geoid ondulations 
  • gravity anomalies 
  • components of deflection of the vertical

using ellipsoidal global model coefficients (Nmax= 360) developed in ellipsoidal harmonic functions (derived from global model EGM96)
