This dataset contains part of the results of the SD4EO project, including images corresponding to the use case of human settlement monitoring. The dataset contains images that have been simulated corresponding to different sensors of the Sentinel 2 satellites. Each image in the dataset includes pixel-level labels for each element present in the image, ensuring perfect accuracy due to the synthetic nature of the images. This eliminates common errors in manual or semi-automatic labeling processes. Multispectral images includedSentinel 2: Images from bands 2, 3, 4 and 8.

This tool will be soon available to enable the generation of new datasets. This research work has been funded by the European Space Agency (ESA) under the FutureEO program and the SD4EO project (Contract No.: 4000142334/23/I-DT), supervised by the ESA Φ-lab.
