It combines multiple global elevation datasets including Copernicus DEM, ALOS World 3D, and object height models, and refines them using nearly 30 billion high-quality ground elevation points from ICESat-2 and GEDI. A two-stage random forest model ensures both global coherence and local accuracy, producing a bare-earth terrain model that minimizes the effects of vegetation, buildings, and DEM artifacts.</p> <p> For more details on this project see the following resources: <ul> <li><a href='https://zenodo.org/records/18887460' target='_blank'>GEDTM30 Zenodo Repository</a></li> <li><a href='https://codeberg.org/openlandmap/GEDTM30' target='_blank'>GEDTM30 Codeberg Repository</a></li> <li><a href='https://peerj.com/articles/19673/' target='_blank'>GEDTM30 Publication</a></li> </ul></p> <p><i>Disclaimer: This data product was generated using machine learning methods.
