In this paper, we introduce LagunAR, a mobile outdoor Augmented Reality (AR) application for providing heritage information and 3D visualization on a city scale. The LagunAR application
was developed to provide historical information about the city of La Laguna in the XVI century, when
it was the main city in the Canary Islands. The application provides a reconstructed 3D model of the
city at that time that is shown on a mobile phone over-imposed on the actual city using geolocation.
The geolocated position is used also for providing information of several points of interest in the city.
The paper describes the design and implementation of the application and details the optimization
techniques that have been used to manage the full information of the city using a mobile phone as a
sensor and visualization tool. We explain the application usability study carried out using a heuristic
test; in addition it is probed by users in a qualitative user test developed as preliminary research.
Results show that it is possible to develop a real-time application that shows the user a city-scale 3D
model and also manages the information of the points of interest
