Absolute Location: Defining Exact Positions on Earth with Latitude and Longitude

Absolute location specifies the precise position of a point on Earth's surface using a geographic coordinate system — latitude and longitude.

Core Concepts

• Latitude: Angular distance north or south of the Equator (0°), ranging to 90°N (North Pole) and 90°S (South Pole). Lines of latitude are parallels.
• Longitude: Angular distance east or west of the Prime Meridian (0°, Greenwich, UK), ranging to 180°E and 180°W. Lines of longitude are meridians.
• Format: Degrees (°), minutes ('), seconds (") or decimal degrees (e.g., 34.0522° N, 118.2437° W for Los Angeles).

Applications

• GPS/GNSS: Receivers calculate absolute position from satellite signals.
• Mapping & GIS: Base layer for spatial analysis, navigation, surveying.
• Navigation: Aviation, maritime, and land routing.
• Geocoding: Converting addresses to coordinates.

Contrast: Relative Location

Relative location describes a place in relation to others (e.g., "20 miles north of London"). Absolute location is fixed, objective, and universal.
