AS/NZS ISO 6709:2023
[Current]Standard representation of geographic point location by coordinates
AS/NZS ISO 6709:2023 identically adopts ISO 6709:2022 which specifies the representation of latitude and longitude and optionally height or depth compatible with previous editions of AS/NZS ISO 6709. This document also supports the representations of other coordinate types and time that can be associated with those coordinates as defined through one or more coordinate reference systems (CRS).
