 This study examined the capabilities of Sentinel-2S2 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 SWIR bands for vegetation mapping.
