Lidar Density, How Much Is Enough?

When it comes to lidar, how much density do we really need, and will even more density be needed in the future? How do we quantify and report density? National programs are moving from 8 points-per-m2 to 20 points-per-m2 and even higher density requirements are emerging globally. Some infrastructure applications are now requiring well over 100 points-per-m2. What is the likely limit as density requirements continue to evolve? A panel of experts discuss the current and future requirements for lidar densities for their applications and customers, and just how many points will be ‘enough’ in the future.
