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.
- Land Information New Zealand’s (LINZ) 1-meter DTM’s covering partial areas of New Zealand
- Land Burgenland’s 50-centimeter DTM’s covering state of Burgenland, Austria
TopoBathy layer is updated with:
- Swisstopo’s 1-3 meters swissBATHY3D bathymetric datasets covering lake beds of Switzerland
- USGS’ 1-3 meters CoNED topobathymetric datasets covering partial coastal areas of California, Chesapeake Bay, New Jersey/Delaware, Mobile Bay, Tampa Bay and North Carolina.
Let’s see a few examples highlighting the improvements.
