This week's module focused on how to generate DEM's, DSM's, and tree heights and densities from LiDAR data. The study area for this module is the Shenandoah National Park located in Virginia. This module introduced me to working with LAS datasets and LAS-related ArcGIS tools such as the LAS to MultiPoint tool or the LAS Dataset to Raster tool.
This layout contains the LiDAR scene as well as the DSM I had generated.
This layout depicts the tree height distribution in the quadrant. The graph tells us that most of the trees in the area are 54.69 ± 20.55 ft in height. There are very few trees taller than 90 ft in the area. There are a few “trees” with negative values, but these can be attributed to the man made features in the area.
And this is a layout of the canopy density of the quadrant. This layout clearly depicts the man-made features such as Skyline Dr to the east.
