# API Reference¶

## 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

## Datasets¶

 The absolute path to the sample data storage location on disk. Fetch a global grid of Earth gravity. Fetch a global grid of the geoid height. Fetch a global grid of Earth relief (topography and bathymetry). Fetch total-field magnetic anomaly data of Great Britain. Fetch gravity station data from South Africa

## Utilities¶

 test([doctest, verbose, coverage, figures]) Run the test suite.
