Lesson 10c3: Clipping LAS Data and Creating Derivative Products in Global Mapper
By the end of this lesson, you will be able to load multiple LAS files, define and use a polygon area of interest to subset LAS files, and generate and export raster surfaces and contours derived from the LiDAR point cloud. If necessary, please review Lesson 10c1 for guidance with importing LAS files, filtering, and visualizing LiDAR point clouds in Global Mapper.
