 This study examined the capabilities of Sentinel-2, S2, satellite data for mapping crop types and tree species. It found that S2 data can provide accurate and reliable crop and tree species maps when combined with other spectral bands. Additionally, it showed that the near-infrared, NIR, bands were less important than the red-edge and SWR bands for vegetation mapping.
