Data updates to Living Atlas World Elevation Layers and Tools (March 2022)

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:

Canada's HRDEM 1 meter coverage
New Zealand's LINZ 1 meter coverage

TopoBathy layer is updated with:

Ready-To-Use Elevation Tools:

Ready-To-Use Elevation Tools (ProfileViewshed and Summarize Elevation) are also updated with the USGS’s latest 1/3 arc second and 1 arc second datasets.

Let’s see a few examples highlighting the improvements.

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.
