LiDAR (Light Detection and Ranging), is a remote sensing method that uses a pulsed laser to measure distance to an object or surface. LiDAR has been collected in 2010 and 2017 via aerial capture resulting in 3D point clouds of the City. Today, these datasets and derived products are used by several city agencies for use in storm surge modeling, change detection, and countless other projects and initiatives.
