The field of geodesy studies the measurements and representation of the Earth. Wolfram|Alpha provides tools for examining this representation as well as examining other aspects of the world, such as its geogravitational and geomagnetic fields. Obtain coordinates, calculate distances and explore the distance to the horizon.
Find the coordinates of locations around the world or find what exists at a particular set of coordinates.
Visualize the meaning of compass bearings.
Compute Earth's geomagnetic field anywhere on the globe and at any time in recent history.
Calculate distances between points on the Earth. Determine the limits of the horizon.
Get information about the properties of a wide range of geodetic reference ellipsoids.
Calculate the gravitational field for any point on Earth's surface.
