High resolution data updates to Living Atlas World Elevation Layers and Tools (December 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 datasets.

Terrain and TopoBathy layers are updated with:

New Zealand coverage
USGS 3DEP 1m coverage

Let’s see a few examples highlighting the improvements.

Gdynia, Poland – improvements over Gdynia region depicted with lidar derived 1-meter DTM in comparison to 24 meters WorldDEM4Ortho

Ready-To-Use Elevation Tools:

Ready-To-Use Elevation Tools (ProfileViewshed and Summarize Elevation) are also updated with 10 meter DTM’s of Northern Ireland.

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.

To see the coverage extents of each source comprising World Elevation services, check out the Elevation coverage map.

You can help in improving these services by contributing high-resolution elevation data to Living Atlas of the World. To participate and learn more, check out the Esri Community Maps for Elevation program.
