High resolution data updates to Living Atlas World Elevation Layers (Sept 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 are updated with a few high-resolution elevation datasets.

Terrain and TopoBathy layers are updated with:

TopoBathy layer is updated with:

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.

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.
