High resolution data updates to Living Atlas World Elevation Layers (Oct 2019)

ArcGIS Living Atlas of the World provides foundation elevation layers and tools to support analysis and visualization across the ArcGIS platform. These layers get updated quarterly with high resolution elevation data from open sources and community maps program. In this release, world elevation layers are updated with a few high-resolution elevation datasets as below.

Terrain and TopoBathy layers are updated with:

TopoBathy layer is updated with:

In this release, approximately 346,000 square kilometers of new coverage of USGS 3DEP 1 meter has been added. The graphic below shows the new addition (magenta) along with previously available coverage (green).

Here are a few examples highlighting the improvements with before and after images.

Two Point Mountain, Idaho – highest peak of 3086 m (10124 feet) in the Boise Mountain depicted with USGS 3DEP lidar derived 1 meter in comparison to NED 10 meters

Terrain and TopoBathy layers have pre-defined pop-ups, which are enhanced to include many key metadata fields to help understand the datasets better. Default pop-up now also includes a SQL query syntax, which you can use (copy/paste) for definition query in the ArcGIS Desktop applications (Pro, ArcMap) to filter a dataset to work with.

These data updates will be rolled out to the other world elevation tiled layers – Terrain3D, TopoBathy3D, World Hillshade and World Hillshade (Dark) in the next quarter.

For more information about the various data sources available in World Elevation services, check out the Elevation coverage map. You can help improving these services by contributing high-resolution elevation data to Living Atlas of the World.

About the author

Rajinder has more than 16 years of experience in GIS and Remote Sensing. He came to Esri about 12 years ago and has worked with various teams in different capacities. In his current role, he leads the community elevation program at Esri and has wide experience in cartographic visualization, image processing, databases and geo-processing. By virtue of his strong research interest in terrain visualization, Rajinder has developed a multi-directional hillshade (esriurl.com/NextGenHillshade) algorithm to improve terrain visualization in Esri basemaps, which is also available as part of world elevation layers. He has also developed a fusion technique (esriurl.com/NAGIfusion) which maintains details and colors when integrating colored rasters with hillshades. Rajinder holds a Master of Science degree in Geoinformatics from the International Institute for Geo-Information Science and Earth Observation (ITC), The Netherlands, and a Bachelor of Science degree in Urban & Regional Planning from GND University, Amritsar, India.
