The city of Espoo has launched a trial where citizens use their smartphones to help local authorities identify road infrastructure that needs to be fixed.

By using their phone cameras, residents can take photographs of problems they spot while on the move and upload them online using Mapillary – an app that lets people share images and tag their geographic location.

Once the pictures are uploaded on the map, the application blurs the face of pedestrians and car number plates to ensure privacy and security.
