Team Digitally Recreating Venice To Preserve It

They have used a LiDAR (light-detection and ranging) scanner, which sends out a pulsed laser light towards the target object and measures the time it takes the laser to return. It calculates the distance the light has travelled, and plots that point in a digital 3D space. The LiDAR has recorded inscriptions so high up they cannot be read from the ground. – The Art Newspaper
