Greys River, WY (532 nm)

Overview

This dataset was collected as an NCALM Seed grant for PI Christopher Tennant of Idaho State University. The survey consists of two corridor polygons on the Greys River between Alpine, and Afton, Wyoming. The collection enables an evaluation of whether changes in hydraulic geometry at process domain boundaries are stepwise or gradational within a mountainous catchment.

This survey was performed with an Optech Titan multispectral airborne LiDAR sensor mounted in a twin-engine Piper PA-31-350 Navajo Chieftain (Tail Number N640WA).
