MyOMap
MyOMaps is an application that lets you load an orienteering map into your smartphone and use the GPS capability of the phone to participate in the event. Of particular interest is the ready availability of permanent courses in many of Melbourne's parks. These can be loaded into the application - no need for a paper map.
