Press Release:
Validate Hyperspectral Data With A Spectral Evolution Field Spectroradiometer

Haverhill, MA – May 14, 2020 – Satellite and airborne hyperspectral imaging is a technology used in a wide range of remote sensing and geological applications. Ground truthing provides the ability to check and fine-tune the results of hyperspectral activities. Spectral Evolution designs and manufactures field portable spectroradiometers, spectrometers and accessories to make field research easier, more reliable, and more
accurate.

Hyperspectral imaging allows researchers to detect patterns and identify surface materials from a distance. Hyperspectral image data can be collected from satellites, airplanes, or UAVs. Hyperspectral imaging systems acquire images in over one hundred contiguous spectral bands. Hyperspectral imaging collects data to generate a data cube that can reveal objects and information. Each scanned area leaves a unique spectral signature, also called a spectral reflectance curve, in various bands of the spectrum, based on its spectral reflectance. Hyperspectral imaging can provide important information on vegetation health whether measuring crops, fields, or forest canopies and can identify minerals in surface features including outcrops, pits and benches.

Applications of hyperspectral imaging in remote sensing and geological remote sensing
include:

• Agriculture: crop stress, yield prediction, soil quality, fertilization/over
fertilization
• Forestry: forest species identification, canopy studies, pest identification
• Environmental: wetlands monitoring, land degradation, climate change effects
• Marine ecology: impact of runoff, eutrophication and harmful algae
• Geology: mineral identification, lithography, alteration mapping

Spectral Evolution’s spectrometers and spectroradiometers are single point systems that cover the full VNIR and SWIR spectral range from 350-2500nm. Remote sensing models include the SR-6500, RS-8800, RS-5400, PSR+™, RS-3500 and PSR-1100f. For mineral identification we offer the oreXpress™, oreXplorer™ and oreXpert™. These instruments are designed for field use – rugged design and construction, no moving parts, lightweight and powered by lithium-ion batteries. Our instruments will typically deliver better spectral resolution and signal to noise capabilities than hyperspectral imaging cameras. Our field portable spectrometers and spectroradiometers deliver measurements that can be used as ground truthing datasets to validate the data produced by hyperspectral imaging systems. Ground truthing is a necessary step in improving the accuracy and analysis of data collected via hyperspectral imaging and corroborates or contrasts with hyperspectral images from satellites and UAVs that can be affected by environmental conditions, ground cover and other field variabilities. Ground truthing can provide a true measurement of a research area.
