providing detailed classifications for various grid types, projections, and modeling subdomains.
(1). WGS84 is a geodetic system that uses IAG-GRS80 as a basis.
(2). With respect to code figures 0, 1, 3, 6, and 7, coordinates can only be unambiguously interpreted if the coordinate reference system in which they are embedded is known. Therefore, defining the shape of the Earth alone without coordinate system axis origins is ambiguous. Generally, the prime meridian defined in the geodetic system WGS-84 can be safely assumed to be the longitudinal origin. However, because these code figures do not specify the longitudinal origin explicitly, it is suggested to contact the originating center if high precision coordinates are needed to obtain the precise details of the coordinate system used (effective as from 16 November 2016).
