Location

In geography, location or place is used to denote a region (point, line, or area) on Earth's surface.

A locality, settlement, or populated place is likely to have a well-defined name but a boundary that is not well defined, but rather varies by context.

London, for instance, has a legal boundary, but this is unlikely to completely match with general usage.

Relative location is widely used for travelling and shipping because it helps people know where a place is compared to another.

For example, longitude is the number of degrees east or west of the Prime Meridian, a line arbitrarily chosen to pass through Greenwich, England.
