locationanchoring
Location anchoring is a concept in geospatial information systems and augmented reality that refers to the practice of associating digital content, objects, or data with a specific real-world location so that it remains aligned with that location across devices and contexts. An anchor is defined by coordinates or a local reference frame, and it may persist despite changes in user viewpoint, orientation, or device.
Techniques and components include outdoor anchoring to global coordinates via GNSS, indoor positioning using Wi‑Fi, Bluetooth
Applications and challenges encompass augmented reality experiences, digital twins of physical spaces, location-based games, and wayfinding.
