Software for Oelsmann et al. 2026 Nature Communications This dataset accompanies the Nature Communications article: Oelsmann, J. et al. Subsidence more than doubles sea-level rise today along densely populated coasts. Nature Communications (2026). Article DOI: https://doi.org/10.1038/s41467-026-72293-z Source data The original input datasets are not republished in this Zenodo record. They are available from their original repositories and were processed, interpolated, or aggregated onto the DIVA coastal grid as described in the associated article and github repository.

InSAR data were used where available for major coastal cities, deltas, Europe, the United States, New Zealand, and China. GNSS estimates were used in additional densely populated areas and remote islands where appropriate. OE24 was used for remaining coastal segments, and GIA estimates were used where OE24 was unavailable. All datasets were mapped to DIVA coastal segments. High-resolution InSAR data were first interpolated or aggregated on the high-resolution DIVA grid and then averaged to the lower-resolution global coastal-segment grid used for the main analysis. The uncertainty variable combines available formal uncertainties with cross-validation and spatial uncertainty terms for InSAR-based estimates, and uses the published uncertainty estimates for OE24 and GIA where applicable. Software and reproducibility The software used to process the input datasets, combine VLM sources, generate the final coastal-segment products, and reproduce the main and supplementary figures is provided in a separate GitHub repository archived on Zenodo.
