Updates to Living Atlas World Elevation Layers (Nov 2018)

ArcGIS Living Atlas of the World provides foundation elevation layers to support analysis and visualization across the ArcGIS platform. In this release, a new Dark Hillshade layer is introduced and world elevation layers (Terrain and TopoBathy) are updated with the following elevation datasets:

 Terrain and TopoBathy:

TopoBathy:

Here are a few examples showing improvements.

Nordrhein-Westfalen is the most populous state in Germany and with the addition of 1 m lidar derived bare earth elevation, it gains significant improvements over Airbus WorldDEM4Ortho 24 m data (which include trees/forest heights). The enhancements are specifically noticeable in urban areas and vegetation/forest areas. In the comparison below, forest areas are depicted as bare earth in the after image showing improvement.

Koln, Nordrhein-Westfalen, Germany – fine details depicted with 1 m lidar DTM over WorldDEM4Ortho 24 m

Vienna, Austria – Improvements shown with 1 m lidar DTM over 10 m Austria

South Sister, Oregon – highest volcanic peak at 10,363 feet (3,159 m) among Three Sisters depicted fully with 1 m NRCS DTM over previously mixed resolution of 10 m & 3 m 

These updates will also be rolled out to other world elevation derivative products – Elevation 3D (Terrain3D and TopoBathy3D) and World Hillshade by next quarter.

For more information about the various data sources available in World Elevation services, check out the Elevation coverage map. Esri will keep improving the World Elevation services, Tools and derivative products by including high resolution data from open source and the Esri Community Maps program. Additionally, to contribute high-resolution elevation data to Living Atlas of the World, check out the Esri Community Maps for Elevation program.

About

Rajinder has more than 15 years of experience in GIS and Remote Sensing. He came to Esri about 11 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.
