WizAnn Radius Maps Application - The complete tool for pointing and revising the Radius Maps for the Knowledge of London. When studying to become a licensed London taxi driver you will be required to search the quarter mile radius at the start and finish of each bluebook point. The app contains all radius maps in both bluebook order and geographical order, so regardless of the way you choose to study them you will be able to make good use of this tool. The points are displayed clearly on colour maps and the filters are in plain view and easy to operate. Revision is straight forward and you can create custom revision lists. The search function allows you to search for any specific point in the maps.
