Abstract: In a method of mapping a real-world process control environment, a mobile device is registered at a reference location, and 3D positions and orientations of the mobile device are tracked using an inertial measurement unit. A user input indicating that a new node is to be added to a 3D map of the process control environment is detected, and a 3D position of a real-world object relative to the reference location is determined, or caused to be determined, based on a tracked 3D position and orientation of the mobile device. A node database is caused to add the new node to the 3D map of the process control environment, at least by causing the 3D position of the real-world object to be stored in association with the new node.
