Remote sensing spectral bands
WebMar 1, 2008 · While most sensors aforementioned collect multispectral images with dozens of spectral bands, hyperspectral imagery acquired by some other sensors may have hundreds of spectral bands. Note that the principle for mapping vegetation cover from remote sensing images relies on the unique spectral features of different vegetation types. WebNov 12, 2024 · We addressed these questions using remote sensing data collected with consumer-grade cameras with four spectral bands and 10 cm spatial resolution on an unmanned aerial vehicle (UAV), airborne imaging spectrometer data (AVIRIS-NG) with 372 bands and 2.5 m spatial resolution, and a fused data product of both datasets.
