Creating task-specific maps with map content transformations

Abstract

Many mobile applications rely on maps in some form. However, the kind of map that is needed depends on the application and also on the user. However, conventional mapping systems employ on a one-size-fits-all approach, settling on compromises that work reasonably well for many applications. In order to deliver the exact kind of map that is required in a specific situation, we introduce a method that transforms OpenStreetMap data according to scripts that can be specified by the user. The result has the same data format as the original, but is adapted to the specific use case that the writer of the script had in mind. Thus, different representations of the same base data can be constructed when it is needed. As an example case of a user group that can profit from such content transformations, we conducted a user study with blind people which shows that they can benefit from transformed maps.
