For the Normal Earth correction, see package boule.

Equivalent Layers

EQLHarmonic([damping, points, relative_depth])

Equivalent-layer for generic harmonic functions (gravity, magnetics, etc).

EQLHarmonicSpherical([damping, points, …])

Equivalent-layer for generic harmonic functions in spherical coordinates

Forward modelling

point_mass_gravity(coordinates, points, …)

Compute gravitational fields of point masses.

prism_gravity(coordinates, prisms, density, …)

Gravitational fields of right-rectangular prisms in Cartesian coordinates

tesseroid_gravity(coordinates, tesseroids, …)

Compute gravitational field of tesseroids on computation points.

Isostasy

isostasy_airy(topography[, density_crust, …])

Calculate the isostatic Moho depth from topography using Airy’s hypothesis.

Input and Output

load_icgem_gdf(fname, **kwargs)
