In Melbourne, Australia, Children’s charity Plan International worked with mapping company Crowdspot to create the Free To Be map.  Free To Be asked women to share their experiences of living and working in the city, pinpointing places on the map where they felt safe, happy or unsafe. The goal of the project was to gather data on sexual harassment and make the city a safer place for women and girls.

The information is being shared with the police service, public transport officials, bar owners, architects, the city council and others.

This seems like a valuable idea and resource for any major city. I’m not sure how you might monetise it, but company sponsorship and advertising seem the most obvious routes.
