Burn Scar Identification with a Field Spectroradiometer

Burn scar measurements provide important information for researchers studying agriculture, vegetation, soil and climate change. Typically burn scar information is taken from satellite, flyover or UAV scans. The data captured by these systems requires field validation. A field spectroradiometer such as the Spectral Evolution SR-6500, RS-8800, NaturaSpec™, PSR+ or RS-3500 can be used to acquire spectral data that supports, contradicts or fills-in the missing data for hyperspectral burn scar measurements.

Data acquired in the field can be enhanced using a number of Vegetation Indices, including the Normalized Difference Vegetation Index (NDVI), Soil Adjusted Vegetation Index (SAVI) and Enhanced Vegetation Index (EVI) all of which are available in our DARWin SP Data Acquisition software. Other Vegetation Indices like the Normalized Burn Ratio (NBR) can also be used along with different algorithms and programs like ENVI since all spectral data is saved as an ASCII file.

Spectral Evolution field spectroradiometers are rugged and reliable instruments with no moving optical components for in situ measurements. They offer high resolution/high sensitivity for accurate and precise spectra.

All Spectral Evolution instruments include DARWin SP Data Acquisition software that captures all spectra and metadata and stores it in an ASCII file for use with other analysis software programs. DARWin software also includes pull-down menu access to 19 vegetation indices including NDVI.

In addition, optional EZ-ID software allows you to capture spectra from known samples and build your own library to match target samples against.

All instruments are available with a range of accessories including multiple lens sizes, pistol grip, backpack, tripod and other accessories. Contact us today for additional information or to receive a quote.
