This paper introduces the issues of cartographical presentation of spatial data in indoor navigation systems. The research covers ensuring appropriate map communication process from modeling spatial data (creating databases) to formulating a cartographical message for the final recipient. The use of construction drawings and architectural plans in the process of visualization is a considerable limitation and can be applied only in the testing phase of navigation systems. Indoor plans created by graphic designers also limit the functionality of the system. For this reason, it is necessary to apply GIS vector data models and cartographical methodology in the development process of maps dedicated to indoor navigation purposes. Moreover, what poses a vital issue is the presentation of a building at many levels of detail (data generalization) and appropriate symbolization designed for displaying on the small screen of a mobile device during the user's movement. In a spatial database, apart from a classic navigation graph, additional vector data of probable indoor movement traces should be saved, which would allow for generation of navigation directions as well as optimal cartographical visualization of calculated routes.
