Geographic Coordinate System
A Geographic Coordinate System (GCS) is a method used to pinpoint locations on the Earth’s surface using a grid of latitude and longitude lines. Latitude measures how far north or south a place is from the Equator, while longitude measures how far east or west it is from the Prime Meridian. Together, these coordinates create a unique address for any location, allowing for precise mapping and navigation. This system is essential for activities like GPS navigation, cartography, and geographic information systems (GIS), helping us understand and interact with our world accurately.
