Methodology family
Imaging spectroscopy
Techniques that exploit continuous or near-continuous spectral coverage across visible, NIR, and SWIR wavelengths to identify materials, gases, and surface composition from their spectral fingerprints.
Methodologies in imaging spectroscopy
- Hyperspectral classification Identifies surface materials or land-cover classes from full spectral fingerprints; good for geology, vegetation stress, and mineralogy mapping.
- SWIR absorption - global screening Wide-area survey for anomalous methane or CO2 concentrations at coarse spatial resolution; good for prioritising follow-up with finer sensors.
- SWIR absorption - point-source Detects gas absorption features (CH4, CO2, CO) at SWIR wavelengths from a single point or facility source; good for industrial emissions monitoring and leak detection.
- SWIR absorption - regional flux Estimates area-integrated greenhouse gas flux over agricultural, wetland, or basin-scale regions; good for national inventory support and carbon accounting.
