Software User Interface
The software interface brings image acquisition, data analysis, spectral-profile viewing, and scanning controls into the measurement workflow.
Typical Applications
Choose the model for the wavelength region required by the application. The visible-band examples below fall within the VS100 spectral range.
Agriculture
Crop stress and disease monitoring. Hyperspectral imaging detects spectral and spatial changes associated with pests, disease, and crop stress. Chlorosis and wilting produce distinct spectral signatures. Comparing healthy and affected vegetation can help identify disease type and assess severity.
Crop nutrient status monitoring. Hyperspectral remote sensing can assess nutrient status and crop growth to support timely management decisions. The contiguous bands and finer spectral resolution of UAV hyperspectral imaging provide more sensitive discrimination of crop responses across wavelengths than multispectral systems.
Forestry
Forest disturbance and fire monitoring. Vegetation-cover and soil-related spectral indices support forest-fire detection and burn-severity assessment, helping teams evaluate large areas rapidly.
Tree species classification. Continuous visible-to-near-infrared data capture subtle reflectance differences among leaves, bark, and other plant tissues. Band-specific features can help distinguish tree species, including those with similar leaf shapes.
Aquatic Environment Monitoring
Fine spectral resolution supports identification and estimation of chlorophyll, tannic acid, and suspended sediment in water. Hyperspectral data also support algal-growth monitoring and studies of phytoplankton distribution and fish-school location.
Chlorophyll shows strong absorption in the blue (400–500 nm) and red (600–700 nm) regions and higher reflectance at 700–750 nm. These spectral features can help estimate chlorophyll concentration and monitor trophic conditions and algal blooms.
Mineral Identification and Geological Exploration
Hyperspectral remote sensing identifies and maps surface mineralogy for mineral-resource exploration. Applications include hydrothermal alteration mapping and geochemical and geological mapping. Characteristic spectral responses help extract detailed information about mineral composition.
Camouflage Material Identification
Hyperspectral imaging uses spectral differences between objects and camouflage materials to detect concealed objects and distinguish material types. In defense-related applications, short-wave infrared hyperspectral imaging can also support identification of camouflage netting in complex field environments.
Research example uses a 400–2500 nm dataset. The listed camera configurations cover 400–1000 nm, 900–1700 nm, or 900–2500 nm.
