DFC30

This repository provides datasets used in the paper "JSPSR: Joint Spatial Propagation Super-Resolution Networks for Enhancement of Bare-Earth Digital Elevation Models from Global Data". This work selected (1) the Copernicus GLO-30 DEM (COP30) dataset as the low-resolution DSM source, (2) the Forest And Buildings removed Copernicus DEM (FABDEM) dataset and FathomDEM dataset as the comparison reference DTM source, (3) the HighResCanopyHeight dataset as the Canopy Height Map (CHM) source, and (4) 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 (DFC30.zip). The DFC30 dataset was preprocessed to 8 m and 3 m resolution samples for network training and evaluation, denoted as DFC30-8m (DFC30_8m.zip) and DFC30-3m (DFC30_3m.zip), respectively. Edit at 2026-01-21: a folder name error was found (DFC30_3m - Lorient - UrbanAtlas), "UrbanAtlas" should be renamed to "UA2012".
