Overview

NCALM logo

This lidar survey was taken by NCALM over a portion of the Snake River watershed in Wyoming for Dr. Carl Legleiter at the University of Wyoming. Two lidar sensors were used during the data collection: the Optech Gemini Laser Terrain Mapper and the Optech Aquarius Laser Terrain Mapper. This landing page is providing access to the data acquired from the Gemini sensor, which is an infrared laser sensor with a wavelength of 1064 nm. Data was collected in August 2012 over an area just north of the Jackson Hole airport.
