Global Positioning

This document defines an extension to the existing OPC UA location models to support global positioning information. It addresses the need to integrate global positioning data (e.g., GPS and EPSG-based coordinates) into industrial systems. Three models are described that build upon one another as follows:

• Global Positioning Model: Defines the core elements – GlobalPositionType, GlobalLocationType, and ZoneType. These elements capture key parameters such as latitude, longitude, elevation, and accuracy in a global context.
• Coordinate Transformation Model: Adds the means to convert local coordinate systems into global ones (e.g., GPS and EPSG-based coordinates) and vice-versa. This model enables a precise and seamless mapping between local and global spatial data.
• Integration Model: Provides the rules and additional elements needed for OPC UA systems to manage and exchange position information. It ensures that data from both local and global coordinate systems can be interpreted consistently.
