ISO 6709:2022 PDF

Scope: 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 s ys tems (CRS ) . This document describes a text string of coordinates, suitable for electronic data exchange, for one point, including reference s ystem identification to ensure that the coordinates unambiguously represent the position of that point. Files containing multiple points with a single common reference s ys tem identification are out of scope. This document also describes a simpler text s tring s tructure for coordinate representation of a point location that is more suitable for human readability.
