  1. "ETOPO 2022 is an updated topographic–bathymetric dataset at 15 arcsec global resolution that incorporates bare-Earth datasets with forests and buildings removed. ETOPO 2022 integrates more than a dozen source datasets for land topography, sea bathymetry, lake bathymetry, and ice-sheet bed elevation data, all of which have been carefully evaluated for quality, accuracy, and seamless integration."

    Quality controlled with nearly a trillion #ICESat2 #LIDAR shots.

    Did some successful microwave keyhole shots back in the day, using #SRTM data. This would have been even better.

  6. #ESA and #NASA satellites deliver first joint picture of #Greenland Ice Sheet melting

    #GlobalWarming is causing the Ice Sheet to melt and flow more rapidly, raising sea levels and disturbing weather patterns across our planet. Precise measurements of its changing shape are of critical importance.
    Scientists have now delivered the first measurements of Greenland Ice Sheet thickness change using #CryoSat2 and #ICESat2

  11. 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 doi.org/10.1038/s41597-024-030. Get it at doi.org/10.4121/21997565, or as an GEE asset `users/maartenpronk/deltadtm/v1-1`. #elevation #terrain
