Data updates to Living Atlas World Elevation Layers and Tools (December 2021)

ArcGIS Living Atlas of the World provides foundation elevation layers and tools to support analysis and visualization across the ArcGIS system. These layers get updated quarterly with high resolution elevation data from federal agencies, open sources, and community maps program. Esri is providing these datasets as ready to use services that benefit the GIS community and extend the use of data in new and innovative ways. In this release, world elevation layers and tools are updated with a few high-resolution elevation and bathymetry datasets.

Terrain and TopoBathy layers are updated with:

3DEP 1m coverage update

TopoBathy layer is updated with:

Ready-To-Use Elevation Tools:

Profile tool has been updated with GEBCO 2021 grid for 500 m (15 arc second) DEM Resolution option.

Let’s see a few examples highlighting the improvements with before and after images.

These data updates will be rolled out to the world elevation tiled services – Elevation 3D (Terrain3D and TopoBathy3D) and Hillshade (World Hillshade and World Hillshade (Dark) ) by the next quarter.
