The terms location and place in geography are used to identify a point or an area on the Earth's surface or elsewhere. The term location generally implies a higher degree of certainty than place, which often indicates an entity with an ambiguous boundary, relying more on human/social attributes of place identity and sense of place than on geometry.
Absolute location - An absolute location is designated using a specific pairing of latitude and longitude in a Cartesian coordinate grid—for example, a Spherical coordinate system or an ellipsoid-based system such as the World Geodetic System—or similar methods.
