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.

I am a recent M.S. in Information Science graduate from the University of Tennessee School of Information Science. I was formerly a graduate research assistant funded by DataONE (Data Observation Network for Earth). Prior, I worked for four years as a content lead and biodiversity scientist with the U.S. Geological Survey's Biodiversity Informatics Program. Building on my work experience in biodiversity and environmental informatics, my work with DataONE focused on exploring the nature of scientific collaborations necessary for scientific inquiry. I also conducted research concerning user experience and usability, and assisted in development of member nodes with an emphasis on spatial data and infrastructure. I assisted with research designed to understand sociocultural issues within collaborative research communities. Through August 1, 2014, I was based at the Center for Information and Communication Studies at the University of Tennessee School of Information Science in Knoxville, Tennessee.
