Web World Wind

3D virtual globe API for JavaScript, developed by NASA. Provides a geographic context, complete with terrain, for visualizing geographic or geo-located information in 3D and 2D. Web World Wind provides high-resolution terrain and imagery, retrieved from remote servers automatically as needed. Developers can provide custom terrain and imagery. Contains a rich set of features for displaying and interacting with geographic data and representing a wide range of geometric objects. More information at worldwind.arc.nasa.gov.
