Guest RTr1031732 Posted August 12, 2001 Share Posted August 12, 2001 What is the term for wgs-84, and what is the use and benefit for it? Thanks Bob Quote Link to comment
Guest mrgigabyte Posted August 12, 2001 Share Posted August 12, 2001 WGS-84 is a map datum that defines how a coordinate system is seated over the ellipsoid. The origin of the wgs-84 system is the center of mass of the Earth, whereas older datum's (i.e. NAD27) had a different origin, making it useful only in North America. GPS receivers use the center of mass of the Earth as their system's origin Quote Link to comment
