Using toolbox functions and reference spheroid classes, you can perform geodetic calculations that account for the curvature of Earth and other planetary bodies. These include 2-D distances, directions, areas, special curves (geodesics, rhumb lines, small circles, ellipses), and intersections on a spheroidal or planar surface. These also include transformations of 3-D locations and vectors (such as velocities and gradients) between geodetic, Earth-centered Earth-fixed, and local (east-north-up, north-east-down, azimuth-elevation-range) systems.
