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

Rosa Ruiloba; François De Vieilleville; Adrien Lagrange; Bertrand Le Saux; Mathieu Pierre-Philippe

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/).
