Human elements of trust and data misuse in open maps

Professor Lynne Coventry explores how participatory mapping like OpenStreetMap empowers communities but faces cybersecurity threats, highlighting the need for trust, awareness, and resilient strategies against data manipulation and malicious attacks.

This talk presents how the National Trust is using OpenStreetMap relations and working with others to promote a common representation to describe walking trails.
