> UNCLASSIFIED > Proposal to amend WGS 84 text for insertion into the AREA header: > > Geographic locations in Australia SHOULD be referenced to the Geocentric Datum of Australia 1994 (GDA94). The Intergovernmental Committee of Surveying and Mapping advises that for most practical applications, [GDA94] coordinates can be considered the same as [WGS 84]; therefore, CAP-AU accepts that for the practical purposes of public alerting, the coordinates derived from a [GDA94] reference system SHALL be considered to be equivalent to [WGS 84] coordinates that are required by CAP v1.2. > Exactly what I had in mind, sounds good. -- Jacob Westfall <[email protected]>
