The digital transformation changes the way the public perceives and interacts with cultural heritage in the museum and beyond. Augmented Reality can be away to address this challenge and to develop new ways to convey information raise awareness and facilitate appreciation of cultural heritage. Application Areas for Augmented Reality (AR) continue to expand and also museums and administered heritage sites are increasingly discovering the opportunities of this technology. This poses challenges for the curator or the management, as they must grasp the technical possibilities and decide with their professional expertise where and how they can arouse interest in the visitor and impart knowledge. Therefore, different factors and requirements from a technician’s and a curator’s perspective arise, which will be analyzed and evaluated in this paper. From the technical side, questions on the tracking method, and device policy have to be made. Especially in connection with in-situ preserved heritage outdoors, marker-based positioning is not ideal. In this case, photogrammetric and videogrammetric models of the heritage object can be used for the tracking and positioning of augmented reality-content. This contribution aims to provide assistance and impulses for AR Applications. Based on this, an AR use case for the UNESCO world heritage Orkhon Valley in Mongolia will be presented, explaining advantages, difficulties and the employed software and workflow.
