I'm happy to announce a new version of our global coastal DTM: DeltaDTM v1.1. 🎉 Now up to 30 m (was 10 m) above the EGM2008 geoid, with improved accuracy across the board. Specifically we now use CopernicusDEM 2023_3 (was 2022_2) as the input and add another year of @NASA #ICESat2 data. The method stayed the same and is described in https://doi.org/10.1038/s41597-024-03091-9. Get it at https://doi.org/10.4121/21997565, or as an GEE asset `users/maartenpronk/deltadtm/v1-1`. #elevation #terrain

I am very happy to announce DeltaDTM, a cutting-edge global coastal Digital Terrain Model (DTM) made by @deltares which was just published in Nature Scientific Data https://www.nature.com/articles/s41597-024-03091-9. Other coastal elevation models are often based on older data, or commercial in nature. DeltaDTM is the most accurate thus far, and free for everyone (CC-BY licensed). This publication is the first paper of my PhD research on creating better global elevation models using #NASA #ICESat-2 and #GEDI data.
