The Wall Street Journal featured a health article on the need to map automated external defibrillators for heart attack response, “The Device that Saves Lives, But Can Be Hard To Find”. Like many health saving devices, such as fire hydrants, many locations aren’t compiled in one easy to access location. The University of Pennsylvania and the Robert Wood Johnson Foundation used crowd sourcing and public participation to map AED locations. The project was called The My Heart Map Challenge , which utilized cash rewards to develop a smartphone app. They are currently creating a toolkit that other municipalities and cities can use to hold their own challenges.
