Sentinel-1 and Sentinel-2 database for refugee camps detection

This database was generated by AGENIUM Space in the framework of the CORTEX project (https://esacortexproject.agenium-space.com/) funded by ESA. Database of pairs of Sentinel-1 and Sentinel-2 images (https://www.copernicus.eu/en, https://scihub.copernicus.eu/) which contain the same region where a refugee camp (from those identified by the UNHCR) is present. Original Copernicus images were acquired between 2017 and 2019. The Sentinel-1 images come from the IW mode and are GRD product from both ascending and descending orbits. The Sentinel-2 images are surface reflectance products (L2A). The initial targeted application is to perform style transfer to generate a Sentinel-2 lookalike from a Sentinel-1 image. The database focuses on refugees’ camps in the Middle East area. As said, the locations of 39 camps were retrieved from the UNHCR (United Nations refugee agency) website (https://www.unhcr.org/). More details are provided in attached document S1-S2-RefugeeCamps-DB-description.pdf This work is funded by a contract in the framework of the EO SCIENCE FOR SOCIETY PERMANENTLY OPEN CALL FOR PROPOSALS EOEP-5 BLOCK 4 issued by the European Space Agency.
