RAQ: Getting Started With LiDAR

Start with a free sample file LiDAR (Light Detection And Ranging) is a technology that essentially takes pictures using laser pulses instead of visible light. You've likely heard about LiDAR in the context of self-driving cars, since the returning laser pulses from a car mounted LiDAR system produce a point cloud telling the car about objects around it in three dimensional space. By using a LiDAR system mounted on an aircraft, the three dimensional information can be used to create topographic maps of the terrain below. Bare earth elevation models are available on MapWarehouse in GeoTiff format. They are easy to use and highly accurate at +/- 10cm. Download the sample file and follow along with the video below to get started with LiDAR.
