 # DeltaDTM Global coastal digital terrain model
 
-DeltaDTM is a global coastal Digital Terrain Model (DTM) with a horizontal spatial resolution of 1 arcsecond (∼30 m) and a vertical mean absolute error (MAE) of 0.45 m overall. It improves upon the accuracy of existing global elevation datasets by correcting Copernicus DEM with spaceborne lidar data from the ICESat-2 and GEDI missions. This correction process involves bias correction, filtering of non-terrain cells (e.g., vegetation and buildings), and gap filling using interpolation. DeltaDTM specifically focuses on low-lying coastal areas (below 10 m above Mean Sea Level) that are particularly vulnerable to sea-level rise, subsidence, and extreme weather events.
+DeltaDTM is a global coastal Digital Terrain Model (DTM) with a horizontal spatial resolution of 1 arcsecond (∼30 m) and a vertical mean absolute error (MAE) of 0.43 m overall. It improves upon the accuracy of existing global elevation datasets by correcting Copernicus DEM with spaceborne lidar data from the ICESat-2 and GEDI missions. This correction process involves bias correction, filtering of non-terrain cells (e.g., vegetation and buildings), and gap filling using interpolation. DeltaDTM specifically focuses on low-lying coastal areas (below 30 m above Mean Sea Level) that are particularly vulnerable to sea-level rise, subsidence, and extreme weather events.
 
 DeltaDTM is a valuable resource for a wide range of applications, including coastal management, flood modeling, and adaptation planning. Its improved accuracy enables more precise assessments of coastal flood risks and supports the development of effective mitigation and adaptation strategies. The dataset is freely available in the public domain and can be easily accessed and utilized by researchers, policymakers, and coastal communities.
