Overview

NCALM logo This dataset was collected using the Optech Gemini Airborne Laser Terrain Mapper (ALTM) using a beam wavelength of 1064 nm.

This dataset was collected as an NCALM Seed grant for PI Jason Alexandra, University of Wyoming.

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).
