WGS84 DatumGeocachers use coordinates to discover a cache. Coordinates listing the position of a location through latitude and longitude. To calculate this position, GPS uses a geodetic datum, which is a system that defines the orientation of the coordinate system. Probably the most present geodetic datum is the World Geodetic System of 1984WGS84), and most GPS receivers are set to it automatically. Before that, cartographers used the North American Datum 1927 (NAD27) to calculate longitude and latitude. The two methods could give two completely different sets of coordinates for a similar physical location.
