World Geodetic System

World Geodetic System (WGS) is a way to measure and locate points on the Earth's surface. It helps scientists measure distances and angles between two points, so they can know how far apart two places are or the directions between them. WGS is also used by navigational devices and to create digital maps. WGS uses special coordinates like latitude and longitude to locate points, and then measure angles and distances between them.
