Used with EZ-ID sample identification software and the Custom
Library Builder module, you can collect known scans and
create a library for comparison. The ability to create
site-specific library allows you to more accurately ,measure
your project area.

Most soil mapping projects start with hyperspectral images from
satellites or flyovers. For a complete and accurate understanding,
field spectroradiometers are needed to ground truth the
hyperspectral  images and to take soil measurements in areas, like
those covered with vegetation, where hyperspectral just doesn't

PSR+ spectroradiometer and the RS-3500 spectroradiometer are
well-suited for soil mapping applications especially in areas that are
not bereft of vegetation and dry. Our spectroradiometers can collect
and analyze the following soil parameters:
  • Soil moisture which can affect crop health, erosion, irrigation,
  • Soil texture - sand and clay can have a huge effect on soil
    health that affect composition, fertility, drainage and more
  • Minerals - identify minerals in the soil that affect composition
  • Organ matter in soil including biomass
  • Soil salinity- can indicate irrigation and fertilization problems
  • Degradation and contamination - whether from natural or man-
    made causes, including pertochemical/hydrocarbon seepage

The PSR+  and RS-3500 are agricultural spectroradiometers ideal for
soil mapping projects. Lightweight, with high resolution and
sensitivity they are easy for one person to use in the field and come
with a range of accessories. In standalone mode, the PSR+  can store
up to 1000 scans. Both systems when used with the GETAC handheld
microcomputer have unlimited scan storage plus a digital camera,
voice notes, GPS, and  altimeter.

When used with the EZ-ID sample identification system and Custom
Library Builder module, researchers can scan known samples and
build a site or project specific soil library to match against target

Soil applications include:
  • Topsoil fertility estimation
  • Erosion risk
  • Hydraulic properties
  • Soil degradation
  • Total and inorganic carbon
  • Total and mineralized nitrogen
  • Cation exchange capacity (CEC) as an indication of soil fertility
  • Moisture content
  • Indirect measurement of soil pH

The PSR+ 3500  is a field portable spectroradiometer for
remote sensing applications including soil mapping.
Researchers use the PSR+ to ground truth hyperspectral soil
images taken from satellites or to collect scans of soil
in situ for a more accurate soil map.
