'When was this photo really taken?' 'Does this location match the official story?' 'How has this landscape changed over time?' As journalists, we face these questions daily. But in today's digital world, answers often lie hidden in plain sight - in social media footage, satellite imagery, and countless other visual and spatial traces. While these materials traditionally served as illustrations for stories, they're now powerful sources of evidence themselves. Through mapping, OSINT techniques, and data analysis, digital breadcrumbs can be turned into investigative breakthroughs, transforming questions into revelations.
