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.
- Poland’s LiDAR derived high-resolution DTM’s of 1 meter covering most of Poland. This brings 24 times more details than previously available data.
- Ordnance Survey of Northern Ireland’s (OSNI) 10 meters DTM covering entire country of Northern Ireland.
- Land Information New Zealand’s LiDAR derived 1 meter DTM’s covering partial areas of New Zealand. In this release, 11,751 sq kms of new data was released bringing total coverage to 70,650 sq kms (see map below).
- Expanded coverage of USGS 3DEP 1 meter lidar derived DTM’s covering areas of the conterminous United States. In this release, approximately 156,000 sq kms (~ 60,231 sq 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).
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
Tautuku, Otago, NewZealand – details depicted in hilly region with LINZ 1-meter DTM in comparison to 24 meters WorldDEM4Ortho
Hot Springs, South Dakota, USA – details in urban area depicted with USGS’ 3DEP 1 meter data in comparison to 10 meters
