Abstract: This paper discusses the requirements for map images such that they are suitable for the construction of location-based services and applications such as mediascapes. We then detail a specific class of maps that satisfy many of these requirements but may lack coordinate information. We show that finding this information easily, quickly and accurately enough for the intended usage is an issue that has not yet been adequately solved. We then introduce a software tool designed to overcome this problem and explain the methods employed to mitigate errors inherent in the process, as well as a detailed description of the algorithm used. The results of a real world application of the tool are then evaluated.
