1、 Definition of airborne hyperspectral imaging

Airborne hyperspectral imaging is a remote sensing technology that combines imaging technology with spectral analysis. It uses aircraft or drones equipped with hyperspectral imaging equipment to collect spatial and spectral information of target objects in continuous spectral bands (usually covering visible light to short wave infrared regions), forming a three-dimensional data cube (two spatial dimensions+one spectral dimension) that integrates spectra.

Core features:

·High resolution:Spectral resolution reaches the nanometer level (usually<10nm), capable of capturing subtle spectral differences

·Multi band:Obtain dozens to hundreds of consecutive narrowband information, far exceeding that of ordinary cameras

·Unified Graph:Each pixel has a complete spectral curve, which enables accurate identification of material composition

2、 Key points for purchasing
