Here's a new take on using map-based search to help travellers, albeit by tapping into what can go wrong.
Pickpocketmap shows the hotspots where tourists have had items stolen with details of when and where the incident took place.
The site was inspired by a tourist from the US who, after being robbed in Paris, was told that it happens every eight minutes.
Pickpocketmap relies on Twitter to find reports of theft and then extracts the location information to plot the incident on a map.
Tourists don't need a twitter account to report an incident as a 'new incident' form is supplied on the home page of the website.
The service also provides a list of the top 10 cities with the most reported incidences of theft and allows tourists to find out more information.
The hope is that by using the service, travellers will become more vigilant.
