While the map has long been the primary means of conveyance for geographical information, augmented reality is increasingly seen as a viable alternative because of its ability to present information from an intuitive perspective to the user. Within the realm of GIS, several examples of augmented reality apps already exist, but they are typically focused on answering a specific visualisation problem. This dissertation project aimed, instead, to produce a universal visualisation tool for geographical information in augmented reality, similar to how traditional GIS software is used in varying analytical and visualisation roles. A proof of concept android app was written using Arthur’s Seat in Edinburgh, Scotland as a case study area. This underwent user testing in the field. Results showed great value in computationally re-projecting geographical information onto the landscape in augmented reality versus a user attempting to do so with a 2D map. Yet user opinion varied on which types of geographical information were most useful to visualise in augmented reality, supporting the need for a universal visualisation tool. Presenting geographical information in augmented reality has the enormous benefit of minimising the effort required to accurately translate information on to the landscape, thereby leaving users free to consider issues of analysis rather than issues of accurate translation.
