Overview

This lidar dataset was collected as part of an NCALM Seed grant for Chelsea Moran at the University of Arkansas. This dataset was collected to help understand the spatial and temporal distribution of large rock blocks and their control on landscape evolution in the Ozarks. The dataset was collected southwest of Harrison, Arkansas, over the Buffalo River.

Platform: Airborne Lidar
