Eel River Critical Zone Observatory July 2014 Lidar Survey (532 nm)
Dataset Identification:
Resource Abstract:
This dataset was collected using the Optech Aquarius ALTM, a hybrid laser mapping system which collects simultaneous land
and shallow water-depth measurements using a beam wavelength of 532 nm. This dataset was collected by NCALM for PI Dr. William
Dietrich, University of California, Berkeley. The Eel River CZO is a multi-disciplinary research collaborative based at the
University of California, Berkeley. CZO research explores how biotic and abiotic factors interact in the near-surface environment
(from bedrook to tree tops) and how these relationships impact environmental processes. The requested survey area consisted
of a 1 km wide corridor, running for approximately 115 km along the Eel river. This survey was performed with 3 airborne remote
sensing mapping systems. Two of these systems are LiDAR systems: 1) Optech Gemini Airborne Laser Terrain Mapper (ALTM) (serial
# 06SEN195) which is an infrared laser mapping sensor and 2) Optech Aquarius ALTM (serial # 11SEN279) 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 two 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). The third airborne sensor was for Hyperspectral
imaging. This portion of the survey was performed with a CASI-1500 - a push broom type hyperspectral imaging sensor sold by
ITRES. It is mounted on a vibration isolated mount together with the Gemini LIDAR sensor. Hyperspectral data are available
via this link.
