>SpecTIR SWIR Sensor

Technology
SpecTIR owns and operates 2 VNIR/SWIR instruments with a spectral range of 450 to 2450 nm, and a stand alone VNIR sensor with a range of 450 to 1000 nm. The spatial range is from 0.5 m to 5 m, and the sensors can be operated in the land based mode for static data collections.

All systems are calibrated using in-house NIST traceable calibration equipment, and have been fitted with state of the art navigation systems that are coupled with differential airborne GPS and enhanced IMUs. The sensors are operated by an experienced team of dedicated data collection personnel. SpecTIR maintains both east and west coast sensor operations and offices to provide complete coverage of the US, as well as international markets. Standard data products are comprised of calibrated radiance and reflectance files with accompanying georeferencing files. Options include a mosaic of the flight lines and exploitation of the imagery.

Sensor Overview
The HyperSpecTIR suite of instruments have a spectral range of 450nm to 2450nm and consist of 227 spectral channels. These instruments can be operated in the ground static-horizontal operation mode, as well as in airborne mode is used to support very high resolution visible, near infrared, and short wave infrared hyperspectral data products. The spatial resolution ranges from 0.1 -3m in the static ground collections to 0.25-5m from airborne collections.

The SpecTIR VNIR Sensor has a spatial resolution from .5m to 5m, with a spectral range of approximately 450 to 1000nm. It is a commercial off the shelf system available world wide. Products from the VNIR sensor range from level 1 imagery which consists of individual flight lines that have been radiometrically calibrated, geometrically corrected and navigated. The level 2 data has been further processed to include a mosaic of the flight lines. Finally, the level 3 data has been analyzed and combined with ground truthing to provide client specified classifications and can be fused with other data sets. The compact size of this system makes this a strong candidate for use on light and unmanned aircraft.

The SpecTIR SWIR Sensor has a spatial resolution of 1.31m at 1000 meters of altitude and a spectral range of 970 - 2,450nm. The spectral resolution and number of spectral channels is user selectable during collections with a maximum 254 number of bands.
