Module 2: Wetland Delineation
Hello all, This week's lab, we learned about some of the applications of LiDAR in forestry and wetland conservation. We used data in the lab to create a density of vegetation map within the boundary of Shenandoah, Virginia. We also used this data to create a distribution of tree height graph showing that the average tree height could be skewed due to the few outliers of trees above 100 ft. As seen in the graph below, most of the vegetation falls between about 45 and 75 ft. Negative values indicate man-made structures. Some of the skills we learned in this lab were how to download data from USGS, Virginia.gov, or other source websites and turn it into usable map elements in ARCGIS, creating map elements such as DSM and DEM used for LiDAR analysis, and how to use LiDAR to calculate various keys of interest such as biomass and vegetation height. Some errors I found I ned to correct were to make sure I was inputting the input and output items correctly. I found out during the CO...
