NIR spectroscopy is well-suited for fast and non-destructive species
identification
in situ. In many cases, field scans can provide the
detailed information not available from hyperspectral satellite or
flyover images.

By mapping an area using a full range spectroradiometer, like the
PSR+, a researcher can measure and discriminate between species.
Measuring reflectance, water absorption features at 970, 1200, 1450,
and 1950 nanometers can show different leaf/plant water content and
help identify the species. Using transmittance, separation of species
can be indicated at 1400 nanometers.

The PSR Series of spectroradiometers provides a full range
(350-2500nm) NIR instrument with the very high resolution and
exceptional signal-to-noise capabilities. Designed for fieldwork, the
PSR Series of agricultural spectroradiometers is lightweight, reliable,
stable, and rugged. It is easily used by one person and can be
configured with a GETAC microcomputer that collects scans and tags
them with GPS data, digital images, voice notes, altimeter readings
and more. Our DARWin SP Data Acquisition software (running on the
GETAC and the spectroradiometer) saves all the data as ASCII files.

When used with the optional EZ-ID and Custom Library Builder
software, researchers can build their own library of known species
quickly and easily and then match new scans to the known samples
for identification. EZ-ID runs on a tablet or laptop for field use.
