UGA LiDAR project for Smokies – highest granularity?
Hi Tommy and Marguerite,
Thanks for the explanations.
The LiDAR point cloud data from The National Map is the first actual LiDAR dataset I have interacted with, so I was not sure what to expect.
The local news covered the project a few years back; Tom Colson was quoted saying "you could see a boulder resting against a tree."
From that I was optimistic the project data might produce a visualization something like this:
Wishful thinking: In that visualization, I noticed today you can actually see several tripods set up within the forest collecting data.
As I got better at using ccViewer I got closer to the kinds of visualizations your report demonstrated.
I grew up in Gatlinburg so there are a lot of features I recognize (I went to school at the elementary school downtown which has distinctive "pods.")
I also downloaded a software called mPointCloudViz <http://www.pointcloudviz.com/> that can drape the .03 m orthoimagery over the point cloud data.
Basically I was looking at this data to see if I could help me tease out certain tree species, specifically HWA damaged hemlock trees.
I was hoping the LiDAR data might offer a way to "fact check" accuracy of photo interpretation work pinpointing the location of hemlock trees, without actually going into the field.
Thanks again for taking a moment to explain what "classification" means.
