Technologist Ed Parsons, Dr Ollie Ballinger and Dr Pragya Agarwal join cultural geographer Mike Duggan in this panel conversation to explore how maps and cartography is being used to reveal what those in power would rather keep hidden. From exposing environmental injustice and geopolitical cover-ups to challenging propaganda and reclaiming erased histories, this conversation uncovers the radical potential of mapping. Together, they examine how cartographic tools, are being used to hold truth to power, uncover hidden inequalities, and challenge dominant narratives.

    His work blends satellites, code, and unconventional datasets to uncover how power and conflict shape the world. After completing a PhD at Oxford on the drivers of insurgent recruitment in Turkey, he began developing open-source tools that turn images and radar data into evidence – from mapping bomb damage to tracing environmental destruction. As a Tech Fellow at Bellingcat, he wrote and built investigations that pushed the boundaries of open-source research.
