Using GIS, Lidar, and Drone Imagery to Visually Represent Landslide Cutback at Deer Run Heights, Jeffersonville, VT

Completed December 14, 2018

 

The landslide located off of Deer Run Heights in Jeffersonville, VT is continuing to be monitored since its original event. While multiple aspects are being studied, this research project attempts to visualize the data in order to demonstrate the cutback that has occurred. This will be completed by creating GIS data with the collected cutback measurements combined with Lidar data to demonstrate the landscape.

Research Objective: To visually demonstrate the cutback at the Deer Run Heights landslide site through maps, video, and 3D models that will be shared with the town of Jeffersonville, the Vermont Geological Survey, and displayed on Dr. Leslie Kanat’s website regarding this landslides research.
