The World Geodetic System 1984 (WGS84) is a global reference system used for mapping and navigation. It provides a standard framework for determining locations on Earth using latitude and longitude coordinates. WGS84 is widely used in various applications, including GPS technology, which relies on this system to provide accurate positioning information. WGS84 is based on a mathematical model of the Earth, known as an ellipsoid, which approximates the planet's shape. This system is essential for various fields, such as cartography, aviation, and geospatial analysis, ensuring consistency and accuracy in geographic data across different platforms and technologies.
