This dataset was collected as an NCALM Seed grant for PI Jason Alexander, University of Wyoming, for the purpose of quantifying the relationship between channel morphology and the topography of large emergent sandbars.
This survey was performed with 2 different LiDAR systems: 1) Optech Gemini Airborne Laser
Terrain Mapper (ALTM) which is an infrared laser mapping sensor and 2)
Optech Aquarius ALTM which is a hybrid laser mapping system as it
collects simultaneous land and shallow water-depth measurements. It operates in the green
spectrum, thus enabling it to penetrate water. These LiDAR mapping systems along with an
Optech 12-bit full waveform digitizer were mounted consecutively in a twin-engine Piper PA-
31-350 Navajo Chieftain (Tail Number N154WW).
LiDAR data acquisition and processing completed by the National Center for Airborne Laser Mapping (NCALM). NCALM funding provided by NSF's Division of Earth Sciences, Instrumentation and Facilities Program. EAR-1043051.
