"NASA Learning Technologies (LT) is a NASA R&D effort for the engineering of teaching tools that deliver NASA content in the most engaging and dynamic manner possible. LT builds the pipeline and the delivery point for unencumbered access to the best data NASA has to provide.
World Windallows any user to zoom from satellite altitude into any place on Earth, leveraging high resolution LandSat imagery and Shuttle Radar Topography Mission (SRTM) elevation data to experience Earth terrain (or any planet with the data) in visually rich 3D, just as if they were really there. Virtually visit anyplace in the world. Look across the Andes, into the Grand Canyon, over the Alps or along the African Sahara."

Our aim here at Learning Technologies is to touch as many people as possible with our products, so making something work (and work well) with MS Windows is top priority. World Wind started it's life with a piece of software called Blue Marble Viewer(this was before I came onboard), which was based on Open Scene Graph.

This created a need for a stable MS Windows product with the same functionality of BMV. With extremely limited resources, C# seemed like the only option that would allow us to have a deliverable product. This leads me into the biggest advantage for using C#..."
