Gravity API API

Overview

The gravitational field of the earth is non-uniform. The <a href='https://en.wikipedia.org/wiki/Geoid'>geoid</a> is the shape the ocean surface would take if only gravity and the rotation of the Earth were considered. The geoid is the surface that defines zero elevation.<br><br> The geoid height is the difference between an ideal reference ellipsoid and the geoid.<br><br> The gravity anomaly is the difference between the acceleration due to gravity on the Earth's surface and the value calculated assuming the reference ellipsoid.<br><br> The official Earth Gravitational Model <a href=https://en.wikipedia.org/wiki/Earth_Gravitational_Model#EGM2008/>EGM2008</a> was developed and released to the public by the National Geospatial-Intelligence Agency (NGA).<br><br> Our EGM2008 API provides on-demand access to the EGM2008 model, as implemented by the open-source GeographicLib <a href=https://geographiclib.sourceforge.io/html/gravity.html>Gravity</a> library.<br><br> API requests must contain a key "API-Key" in the header (see code samples). Obtain a key from <a href='https://developer.amentum.io'>here</a>. <br><br> Amentum Pty Ltd is not responsible nor liable for any loss or damage of any sort incurred as a result of using the API. <br><br> Copyright <a href='https://amentum.space'>Amentum Pty Ltd</a> 2021.
