The benefits of using Geographic Information Systems in archaeology and cultural heritage are undeniable and the use of spatial data has been crucial in shaping a wide number of research fields. Nevertheless, the transition from Geographic Information Systems (GIS) to Indoor Positioning Systems (IPS) has not been adequately studied, despite the very promising uses of IPS in cultural heritage. This paper describes research conducted at the Digital Media Lab, Technical University of Crete. The use of an Indoor Positioning System (IPS) is being tested on a monument in Crete, Greece, in combination with a 3D Point Cloud produced with Structure from Motion Techniques. The selected monument under study is located on the seafront of the 700 years old Venetian harbor of Chania and it used to be the private residence of Ambassador R. Krueger who built it on 1890. The goal is to examine whether 2D data produced by IPS can be enhanced with 3D data from SfM in order to provide an enriched experience of navigation and personalized services customized to each user’s needs. Moreover valuable insights for improving the architectural configuration of the monument’s interior can be extracted by documenting the exact position of each user in space in real time. Software used are Indoor Atlas for IPS and Capturing Reality for SfM.

Relevance for the conference: This study combines Structure from Motion techniques for acquiring 3D models, with Indoor Positioning Systems for navigation in monuments.
Relevance for the session: This study takes GIS in the interior of monuments and tries to combine it with 3D Point Clouds
Innovation: The innovation of the study lies on the effort to combine affordable IPS (without using any hardware sensors) with SfM.
