Light Detection and Ranging (Lidar) data is a different kind of remote sensing data that will allow the user to visualize, analyze, and extract a digital elevation model (DEM), slope and aspect, height of trees, 3D building views, etc. In the United States, the U.S. Geological Survey is collecting high-resolution Lidar data and making them accessible to the public. In this class, students will learn how to download Lidar data and then visualize and analyze it, and extract and create DEMs and 3D building data.
