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:
- Netherland’s (AHN3 and AHN4) lidar derived high-resolution DTM’s of 0.5 and 10 meters covering whole country of Netherlands. This has enhanced the resolution by six times than previously available ~3 meters data.
- SDFE’s lidar derived high-resolution DTM’s of 0.4 and 10 meters covering whole country of Denmark. This has enhanced the resolution by eight times than previously available ~3 meters data.
- Expanded coverage of USGS 3DEP 1 meter lidar derived DTM’s covering areas of the conterminous United States. In this release, approximately 376,000 square kilometers (~145,174 square miles) 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).
Ready-To-Use Elevation Tools:
Ready-To-Use Elevation Tools (Profile, Viewshed and Summarize Elevation) are also updated with 10 meter DTM’s of Netherlands and Denmark.
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.
