Gravity Corrections

bouguer_correction(topography[, …])

Gravitational effect of topography using a Bouguer plate approximation

For the Normal Earth correction, see package boule.

Equivalent Layers

EQLHarmonic([damping, points, relative_depth])

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

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)

Reads data from an ICGEM .gdf file.

Synthetic models and surveys

synthetic.airborne_survey([region, data_region])	Create measurement locations for a synthetic airborne survey
synthetic.ground_survey([region, data_region])	Create measurement locations for a synthetic ground survey
