IML Critical Zone Observatory, Sangamon River, IL Aug 2014 (1064 nm)

Overview

NCALM logo CZO 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 by NCALM for PI Dr. Praveen Kumar, University of Illinois. The Sangamon River area is part of the Intensively Managed Landscapes (ILM) Critical Zone Observatory (CZO).

The requested survey area consisted of two connected rectangles enclosing approximately 198 square kilometers along with their associated watercourse corridors. The project rectangles are located 20 km west of Champaign. IL. The entire enclosed area of these 2 rectangles was surveyed with the Gemini (1064 nm, NIR instrument); the enclosed watercourse corridors illustrate where Aquarius (532 nm instrument) data was also collected.

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 is available via this link.
