Overview

The HD3 research facility has both a lab component with dedicated Geographic Information Systems (GIS) and image processing workstations, as well as a mobile component consisting of a spectroradiometer, multispectral agricultural camera, GPS units, and ruggedized laptops to accurately measure and record spectral signatures while in the field.

A unique component of the HD3 Lab is our access to a high resolution field spectroradiometer. This device allows users to identify specific spectral signatures of different vegetation species and landcovers at a resolution of 3.2 nm. This level of accuracy is crucial for building accurate spectral libraries, currently limited for several species throughout the Southeast. With a precise, all-inclusive spectral library, large scale vegetation analyses via airborne or satellite instruments are possible. From the perspectives of ecology and agriculture, the instrument is useful for applications and measurements including soil nutrient content, crop health and stress, water quality, and invasive species identification and extent.

The HD3 lab is currently testing the Tetracam ADC Lite multispectral camera which utilizes wavelengths from 520nm to 920nm for image collection comparable to Landsat TM2 (green), TM3 (red), and TM4 (near-infrared) with a 3.2 megapixel resolution. These wavelengths are ideal for processing reflected and absorbed light from vegetation and cropland, producing vegetation indices for measuring stressed vegetation, delineating forest canopy and landscape structure, and evaluating agricultural health. These indices include NDVI (normalized difference vegetation index) and SAVI (soil adjusted vegetation index – for sparsely vegetated regions with higher soil reflectance), as well as additional green and red ratios The ADC Lite is a compact, lightweight package, weighing roughly 630 grams (22 ounces), making it ideal for UAV platforms.

With multiple components including GIS workstations, a spectroradiometer, and a multispectral camera, the HD3 lab is the ideal facility in which to evaluate project feasibility and test prototype methodologies for product creation and data collection. Researchers at the HD3 lab collaborate with several groups and programs including NASA’s DEVELOP internship program, UAH’s SMAP Center, Atmospheric Science Department, Earth System Science Program, and Earth System Science Center. With close-knit relationships among researchers and scientists in a broad range of fields, HD3 is able to leverage existing strengths in geospatial analysis and remote sensing within all UAH entities.
