Dimap’s Hyperspectral suite uniquely covers the wavelength range from 400nm to 12000nm, is highly sensitive and extremely stable

 

Dimap combines leading-edge sensors from multiple manufacturers, integrated into a single platform giving greater flexibility and the highest performance compared to sensors from a single source.

 

Dimaps main advantages:

 

The visible near-infrared, VNIR (400 to 1000nm), is a push broom scanner of the highest resolution (1600 pixels) cross-track assuring a high spatial resolution With 160 bands for detailed spectral signatures. This enables higher flying altitudes maintaining the highest spatial resolution while minimizing acquisition costs.

 

The VNIR spectrometer is mainly used for vegetation and aquatic system analysis, but can also provide cost-effective mapping of iron ore deposits.

 

The short wave infrared, SWIR (1000 to 2500nm), is also a push broom scanner providing diverse operational capabilities, a compact sensor with high spectral stability. This provides cost-effective service with no compromise on the quality even under difficult conditions like high altitude applications or helicopter installations.

 

This sensor is mainly used for mineral mapping of most mineral deposit types but can also support target recognition.

 

The Thermal Longwave Infrared Hyperspectral sensor, TIR (7700 to 12000nm), is a Fourier transformation spectrometer combined with special stabilization for up to

 

400 bands maintain a superior signal-to-noise ratio, which is unavailable in other Hyperspectral sensors covering these wavelengths.

 

This TIR allows excellent discrimination of minerals and the detection of various gases like SO2, CO2, NOx, Ozone, and pipeline gases.

 

The field spectrometer, ASD FieldSpec, is used for standard ground truthing which allows the direct implementation of the selected spectra from 350 to 2500nm into the Hyperspectral processing workflow.

The Hyperspectral Laboratory employs a calibrated lighting system modeling a Planck curve between 400 and 2500nm to ensure an absolute clean spectral sample using the VNIR and SWIR Hyperspectral sensors.
