Higher resolution hyperspectral sensors yield greater precision for remote sensing classification applications, producing more information from every pixel generated in an image than ever before. To help maximize the full potential of these next generation sensors, measurements from ground based instrumentation need to meet or exceed the sensor’s spectral resolution. In the absence of this resolution equality, data is interpolated during post processing and vital spectral information can be smoothed and lost.

The enhanced spectral resolution of the ASD FieldSpec® 4 Hi-Res NG spectroradiometer has been designed to meet the rigorous demands of the next generation hyperspectral imaging systems such as AVRIS-NG and HySpex ODIN-1024. In addition to superior spectral resolution, the ASD FieldSpec 4 Hi-Res NG (like all ASD range spectroradiometers), incorporates graded index InGaAs photodiode SWIR detectors to provide the smallest available spectral sampling interval in a field portable device with 1,875 measured wavelengths over the full 350 to 2,500 nm spectral range, ensuring detection of even the most subtle spectral features.
