Geophysical ground measurements, gravity interpolated (overview)
This API provides gridded gravity field data for Sweden, published by SGU (Geological Survey of Sweden). Gravity measurements reveal variations in mass distribution within the Earth's crust caused by differences in bedrock composition. Point-by-point gravity measurements across Sweden have been used to calculate Bouguer anomalies (mGal) in the RG82 reference field, then interpolated into a grid with 500m x 500m cell size. Coordinate-based Bouguer anomaly values matching the grid spacing are extracted into a CSV file, supporting geological mapping and subsurface structural analysis at national scale.Measurements of gravity can be used to map variations in the mass distribution in the Earth's crust. These variations are due to differences in the composition of the bedrock. Geophysical ground measurements, gravity interpolated (overall) contains grid data that illustrates the variations that exist in Sweden's gravity field, expressed as Bougueranomali. From point-by-point measurements of gravity throughout Sweden, Bougueranomalier (mGal) has been calculated in the reference field RG82. These have then been gridded with a cell size of 500m x 500m. From the grid, coordinate Bougueranomalies have been extracted with the same point spacing corresponding to the grid's cell size into a csv file.

Data access
This API doesn't publish a machine-readable schema (such as an OpenAPI spec) that we can read automatically, so there's no field list to show here. See the documentation for its available endpoints and response formats.
