Understanding Gully Erosion With LiDAR

In this research summary these authors from the U.S. Agricultural Research Service explain the work they have been doing with LiDAR to better understand gully erosion processes.

In this study, the effect of point sampling density was investigated at individual gully scales. Overall guiding principles were developed for multi-temporal gully surveys based on various levels of ground-based LIDAR sampling points and relief variation (low, moderate, and high). For each level considered, an analysis of the full dataset was compared to reduced datasets.
