Collected in a single pass using ScanLook with only the Velodyne HD32 scanner,
this video shows the raw, unfiltered point cloud complete with pedestrians and traffic.
The data was captured during the busiest hours of the day to show how little shadowing results even in heavy traffic.
Results are accurate to a couple centimeters and the data is colored according to elevation.
Light Detection and Ranging is used to detect and measure the distance of an object or surface from an optical source.
LiDAR differs from photogrammetry in that photogrammetry uses passive light and LiDAR employs an active laser system.
LiDAR yields an intensity with the XYZ data to provide a black and white-like image.
