ⓘ Location

In geography, location and place are used to identify a point or an area on the Earths surface or elsewhere. The term location generally implies a higher degree of certainty than place, the latter often indicating an entity with an ambiguous boundary, relying more on human or social attributes of place identity and sense of place than on geometry.

                                     

1.1. Types of location and places Relative location

A relative location, or situation, is described as a displacement from another site. An example is "3 miles northwest of Seattle".

                                     

1.2. Types of location and places 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. For instance, the position of Lake Maracaibo in Venezuela can be expressed using the coordinate system as the location 9.80°N latitude, 71.56°W longitude. It is, however, just one way. Alternative ways can be seen in this Geo Hack link.

Absolute locations are also relative locations, since even absolute locations are expressed relative to something else. For example, longitude is the number of degrees east or west of the Prime Meridian, a line arbitrarily chosen to pass through Greenwich, England. Similarly, latitude is the number of degrees north or south of the Equator. Because latitude and longitude are expressed relative to these lines, a position expressed in latitude and longitude is also a relative location.
