Alright!! So, I was able to do some over focusing on the LIDAR stuff, and came up with some rather valuable resources that have already saved me time. I hope this helps you, and that we can grow our shared LIDAR knowledge together!
Firstly, I was able to find free software, that is ONLINE, so your computer is burning up as little as possible. POTREE allows us to view point data in a 3d model, as well as create models based on data gathered.
A walkthrough based on data gathered from OpenTopography, can be found at .
Also, you can get a link to POTREE data provided by the USGS national LIDAR map at their site, this is very convenient for quick looks. Anything more invasive you will have to watch the video, learn to input raw data, and create your own maps.
Here is an example of a point of interest identified by the basic Vermont LIDAR imagery provided by their website. This is the same information used by POTREE to create a 3d image, only in a more manageable 2d format.
Here you can clearly identify the logging roads on the landscape, as well as the point of interest that appears to be a square...thing. It stands out from the rest of the hillside when viewed, and seems to have building foundation qualities.
This is where the POTREE application becomes invaluable in further digital identification. With this application I was able to pull up a 3d image of the hillside, and strip away layers of the trees, shrubs, and surrounding ground to reveal what had truly made this interesting impression.
Now, with the 3d image, you can clearly see that it is very unlikely there is a foundation here, and that there appears to have been a rather sizeable tree that was blown over, pulling up its roots and creating a depression at its base. Even with the fairly certain information, I will still be confirming this with boots on the ground in the spring.
I hope this has helped, and let me know what you think!!
