Which coordinate system uses latitude and longitude for reporting positions?

• A. Geographic Coordinate System
• B. Universal Transverse Mercator
• C. Decimal Degrees System
• D. Cartesian Coordinate System

Answer: (A)

The Geographic Coordinate System is used for reporting positions based on latitude and longitude. This system defines locations on the Earth's surface using two angular measurements: latitude, which indicates how far north or south a point is from the Equator, and longitude, which indicates how far east or west a point is from the Prime Meridian.

This method allows for precise global positioning and is widely utilized in navigation, mapping, and geographic information systems, making it essential for search and rescue operations where accurate location reporting is critical.

In contrast, other coordinate systems like the Universal Transverse Mercator are designed for specific applications and regions, while the Decimal Degrees System is a format for expressing geographic coordinates rather than a separate system. The Cartesian Coordinate System, based on a two-dimensional grid of x and y coordinates, does not incorporate the Earth's curvature and is not suitable for global positioning.
