The French Institute of Cartography and start-up Extra are collaborating to develop a decentralized protocol for this purpose. The Circum protocol will merge LiDAR datasets from various providers, sell this data source to consumers, and redistribute the value back to the original providers. Circum uses blockchain technology and 3D surface reconstruction algorithms to carry out its mission. Learn about the protocol’s key mechanisms with the team at this conference.
