  • 16. 16What is Web World Wind? Web World Wind is a 3D virtual globe API for HTML5 and JavaScript. It is a library and API rather than a stand-alone application. This enables it to be included in any web page or web application as a component.
  • 17. 17How does it work? It has a WebGL internal core but provides a javascript interface to operate with it WWW is open source and available to download on github:  https://github.com/NASAWorldWind/WebWorldWind where also is possible to try different examples. red objects = the parts accessible from the APIs
  • 18. 18 ● High-resolution terrain and imagery, retrieved from remote servers ● Layers: they contain all the information displayed in the World Window. All imagery, shapes and decorations such as the compass are defined in layers. ● Supports REST, WMS and Bing ● Display multiple globes and maps on the same page How does it work?
