This paper addresses the question of how route instructions that include landmarks for indoor navigation can be created automatically based on information available in spatial indoor databases. Existing approaches for the generation of landmark-based routing instructions are designed for outdoor environments and rely mainly on instance-level data about the characteristics of potential landmarks. However, indoor navigation differs from outdoor navigation in various aspects, and indoor spatial databases do not usually contain detailed information about individual objects. Therefore, the proposed method aims to address the specific challenges of indoor navigation and relies only on commonly available data about categories of spatial objects. A case study of a university campus demonstrates that by and large the method produces correct routing instructions that include landmarks. However, it also reveals some gaps in the model and shows possibilities for enhancements for future work.
