 The study presents preliminary results of two classification exercises using Sentinel-2, S2, data for mapping crop types and tree species. In the first case study, an S2 image was used to map six summer crop species in lower Austria as well as winter crops slash bare soil. In the second case study, seven different deciduous and coniferous tree species were mapped in Germany. The study confirmed that S2 data can produce reliable land cover maps with cross-validated overall accuracies ranging between 65% tree species and 76% crop types. The red edge and shortwave infrared SWR bands were found to be important for vegetation mapping while the near-infrared bands were amongst the least important. The study also compared object-based image analysis, OBA, with classical pixel-based classification and found that they achieved comparable results, mainly for cropland. The full potential of S2 data could not be assessed due to single-date acquisitions, but the twin S2 satellites will offer global coverage every five days in the future, allowing for unprecedented spectral and temporal information with high spatial resolution.
