ISO 6709, Standard representation of geographic point location by coordinates, is the international standard for representation of latitude, longitude and altitude for geographic point locations. The first edition (ISO 6709:1983) was developed by ISO/IEC JTC 1/SC 32.
This document specifies the representation of latitude and longitude and optionally height or depth compatible with previous editions of ISO 6709.
This document specifies the representation of latitude and longitude and optionally height or depth compatible with previous editions of 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).

This document specifies the representation of latitude and longitude applicable to data interchange and human-readable representation and maintains strict backwards compatibility with previous editions of ISO 6709.
A discrete global grid ( DGG) is a mosaic that covers the entire Earth's surface. Mathematically it is a space partitioning: it consists of a set of non-empty regions that form a partition of the Earth's surface. [1] .
ISO 6709 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics. This second edition cancels and replaces the first edition (ISO 6709:1983), which has been technically revised. The first edition provided for the representation of latitude and longitude for geographic point locations. This
