Spectral geology from the air.
Most surface materials — clays, iron oxides, carbonates, sulphates, hydroxides, vegetation under stress, hydrocarbon seeps — carry diagnostic spectral signatures in the VNIR and SWIR range. Hyperspectral imagery resolves those signatures at survey speed.
Our pushbroom VNIR-SWIR systems capture 270+ contiguous spectral bands at sub-metre ground resolution. Atmospheric correction, geometric correction, and spectral library matching are applied per project objective — whether that's alteration mapping for mineral exploration, dryland vegetation health, or seep detection over hydrocarbon plays.
Output is a classified surface map tied to your coordinate system, supported by spectral end-member library and per-pixel classification confidence.
Mineral alteration map
VNIR-SWIR classification separating clay, iron-oxide, and carbonate signatures — draped over hillshade for structural context.
Vegetation index map
Radiometric calibration → atmospheric correction (FLAASH/QUAC) → geometric correction → spectral unmixing → end-member library matching → per-pixel classification + confidence.
From spectra to classified surface map.
