Mars Global Surveyor: MOLA SHADR

Spherical Harmonics Topography Model

The MOLA Spherical Harmonics Topography Model  (SHADR) is a numerical transform of planetary radius values from the MOLA gridded data set (EGDR) into spherical harmonics using Simpson's Rule quadrature. When evaluated, the model gives absolute radius from Mars' center of mass in meters.
