    Produced by TastyFreeze in GEO 409, Fall 2019 for the Department of Geography, University of Kentucky. Elevation data derived from lidar point cloud (source: KyFromAbove, kyfromabove.ky.gov). Hillshades were created from a bare-earth DEM and a canopy DSM and displayed with transparency over a 2016 NAIP aerial photograph. Cliff heights were estimated with a focal statistics function that locates elevation ranges greater than 40 feet within 10-foot radius of any cell in the bare-earth DEM.
