Abstract
The technology of augmented reality can significantly improve the presentation of national heritage. This technology provides quick and more intuitive information search about heritage site landmarks compared to classical technologies that use keywords or scrolling lists. In this paper, we present a mobile application based on geospatial augmented reality technology to present outdoor heritage sites. We provide a detailed description dedicated to the hybrid type of
AR tracking that uses ARCore Geospatial API. Also, we present the system's architecture and illustrate its application on the examples of monuments in the city of Niš.
