Collection Overview: This lidar dataset was collected as part of an NCALM Seed grant for Mariel Nelson at the University of Texas at Austin. This dataset was collected to help characterize alluvial channel bank erosion with time-lapse airborne and UAV lidar. The dataset was collected northeast of Houston, TX, over the Trinity River.
