This document defines an extension to the existing OPC UA location models to support global positioning information. This extension addresses the need to integrate global positioning data (e.g., GPS and EPSG-based coordinates) into industrial systems.

Modern industrial applications increasingly require the ability to correlate local spatial data with globally referenced coordinates. For example, asset tracking, multi-site logistics, and remote monitoring benefit from a seamless highly precise transformation between the local coordinate system of a manufacturing environment and geographic locations in navigation and mapping. The extension defined herein introduces new data types, object models, and reference relationships - most notably the GlobalPositionType, GlobalLocationType and ZoneType - that capture parameters such as latitude, longitude, elevation, and positional accuracy in a global context and allow for a precise transformation between the coordinate systems.

This extension ensures that systems built on OPC UA can reliably exchange and interpret position information, regardless of whether it originates from a local or global coordinate system. It thereby enables a coherent and interoperable approach to managing spatial data across both local and global domains within industrial environments.
