**The WGS 84 coordinate system is defined by the following parameters:**
**- The Earth's semi-major axis (a) and semi-minor axis (b)** which define the size and shape of the Earth's ellipsoid.
**- The Earth's flattening (f)** which is the ratio of the difference between the major and minor axis to the major axis.
**- The Earth's eccentricity (e)** which is the square root of the first eccentricity squared (2f-f^2).
The WGS 84 coordinate system also uses a geographic coordinate system, which is based on the latitude and longitude of a point on the Earth's surface. Latitude is the angle between a point on the Earth's surface and the equatorial plane, and is measured in degrees north or south of the equator. Longitude is the angle between a point on the Earth's surface and the Prime Meridian, and is measured in degrees east or west of the Prime Meridian.
