Using lidar to classify landslides

from GIS User

A new algorithm for automated landslide inventorying, named the Contour Connection Method, has been developed that relies on simplified morphological features for analysis. Previous landslide mapping techniques have included field inventorying, photogrammetry, and use of bare-earth lidar Digital Elevation Models to highlight regions of instability. However, many of these techniques do not have sufficient accuracy, resolution or consistency for inventorying landslide deposits on a landscape scale — with the exception being use of lidar bare earth digital elevation models. more
