Package pyaxqg

A pure Python implementation of a biaxial and triaxial reference ellipsoid for the Earth with conversion between geodetic lat-, longitude with ellipsoidal height h and cartesian X, Y, Z with orthometric height H or quasi-geoid height N using bilinear or bivariate spline interpolation of 1-degree, whole Earth grids.

The 5 grid columns Nbiaxial, Ntriaxial, xE, xyE and xzE of the reference ellipsoids Supplementary file 2 are included, making pyaxqg a self-contained package.

See pygeodesy.geoids for other pure Python geoid implementations and height interpolations.

See the pyaxqg main module for some usage examples and comparison with the pygeodesy.GeoidKarney results.

Version: 26.09.02
