The World Elevation services provide online access to global collections of multiresolution, multisource elevation data. This collection includes data with resolutions ranging from over 200 km to less than 1 meter. The services provide a single endpoint for desktop and web applications to access elevation values and derived products.
You can use it in your desktop and web applications
These image services support visualization and analysis, with different services optimized for different purposes. They provide access to the elevation data (raw data) or products (for example, hillshade) you require, without having to store, compile, and process the source data on your local machine. They are available on ArcGIS Online. You can access them individually or search for the World Elevation group to access the entire collection.
The image services provided for visualization can be used as base images in your Desktop applications, such as ArcMap, or web applications to support the other data. The recommended services include
The image services provided for analysis can be used by applications that will use the image service as a source for their own analysis or use the elevation data to process other imagery, such as performing an orthorectification. The recommended services for analysis include
There are several example applications available on ArcGIS Online to demonstrate how you can work with the World Elevation image services. One such example would be the World Elevation Reviewer, which is a sample web application created using Microsoft Silverlight for exploring the World Elevation services.
You must be a member of the ArcGIS Online group to access this link.
The source elevation data is comprised of the best publically available elevation data and samples from commercial vendors. The data providers include:
The data sources include lidar, NED, SRTM, GMTED, GEBCO bathymetry, and EGM2008. They range in resolutions from over 200 meters to less than 1 meter. Not all datasets cover the entire Earth’s surface.
