Description :
This study used airborne laser altimetry (LiDAR) to examine the surface morphology of 2 canyon-rim landslides in southern Idaho. Specifically, the objectives are to develop the use of surface roughness and slope maps, semivariograms, and fractal dimensions using vector point LiDAR elevation data for identifying patterns in morphology, movement history, and material types for the active, smaller Salmon Falls landslide; and use these same morphometric parameters (surface roughness, semivariance, fractal dimension) to compare the active slide with the older and larger 1937 landslide.
