DFC30

We selected (i) the Copernicus GLO-30 DEM (COP30) dataset as the low-resolution DSM source, (ii) the Forest And Buildings removed Copernicus DEM (FABDEM) dataset as the reference DTM source, and (iii) the GRSS Data Fusion Contest 2022 (DFC2022 or grss_dfc_2022) dataset as the high-resolution image, DTM and land use mask sources to build a dataset for real-world DEM SR problems, denoted here as DFC30 (DFC2022 + FABDEM + COP30, low-resolution at ~30 m).
