Multispectral vs. Hyperspectral Imaging – Enhancing Vegetation Mapping Accuracy

8/1/2023

Data from multispectral satellite constellations like Landsat and SPOT have long been utilized for land use mapping and vegetation classification. Sentinel-2 builds on this legacy, providing similar moderate-resolution data acquired in broad spectral bands that cover visible, near infrared, and short-wave infrared wavelengths. Even though...
