STK World Terrain
STK World Terrain
STK World Terrain is a high-resolution, worldwide terrain elevation tileset useful for Earth surface visualization and other uses. It continually grows in size and resolution as new sources of high-quality elevation data are found, acquired, and incorporated into the tileset.
Please send any feedback on this tileset to firstname.lastname@example.org.
Sources of elevation data
STK World Terrain currently includes elevation data from the following sources.
|Source||Coverage||Approximate Maximum Spacing Between Height Samples|
|National Elevation Dataset (NED)||United States||10 meters to 30 meters|
|USGS SRTM 1 Second Global||Approximately -60 to 60 degrees latitude||30 meters|
|CGIAR SRTM||Approximately -60 to 60 degrees latitude||90 meters|

STK World Terrain is provided for use in any application and for any purpose, including both commercial and non-commercial purposes, subject to the following conditions:
- You may not copy, store, or redistribute any portion of the tileset for use in an offline, disconnected, or local environment. Client-side and proxy-based caching are allowed as long as it is a general caching mechanism caching other internet traffic as well, not just STK World Terrain data.
- You may not put an unreasonable burden on the STK World Terrain server(s). If you're concerned that your use may be deemed unreasonable, please contact AGI to discuss it.
- You must clearly display the attribution for this dataset, "© Analytical Graphics, Inc., © CGIAR-CSI, Produced using Copernicus data and information funded by the European Union - EU-DEM layers
- You agree that STK World Terrain is provided as-is and at-will, and will not hold AGI responsible for anything bad that happens as a result of your use of the tileset or your inability to use the tileset.

Offline and disconnected use
To host this tileset on your own infrastructure, you need STK Terrain Server. STK Terrain Server enables use of this tileset in an offline or disconnected environment, such as on a private network disconnected from the Internet. It also allows you to host the tileset closer to your users in order to improve performance, to overlay this tileset with your own terrain data, to create an entirely independent tileset from your own data, and to maintain full control over uptime and availability.
