Geodesy & Navigation

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.

Latitude & Longitude

Find the coordinates of locations around the world or find what exists at a particular set of coordinates.

locate a point on Earth using latitude-longitude coordinates

find the coordinates of a city

Distances

Calculate distances between points on the Earth. Determine the limits of the horizon.

compute the great-circle distance between points on the globe

compute the distance between cities

compute distances between multiple cities

compute the distance to the horizon

compute the horizon distance for radio waves
