NASA World Wind

What is NASA World Wind?

• A richly interactive 3D planetary visualization tool.

• Smart client architecture.• Portal for NASA data.• Integrates data from a

variety of sources.

Why NASAWorld Wind?

• NASA has a great wealth of planetary science data

• Standards-based and highly extensible .NET3D planetary viewing tool– Earth…Moon…Mars…

• Supports research, academia, education and public awareness

Smart Client Technology

• Algorithms optimize the integration and seamless blending of multiple data sources

– Combine diverse data formats of broad ranging resolutions

– Data is streamed simultaneously from multiple servers

Extensible Technology

• API architecture provides for a fully configurable client

– Unlimited customization via plug-ins

• E.g., Real-time tracking of the International Space Station, etc.

– Unlimited functionality via XML files and plug-in modules without any need to change the code

• Digital Aeronautical Flight Information (NGA)

Plug-In Example

• Air Traffic Control

– Flight path visualization

– Air traffic patterns and other 3D simulations readily shared and analyzed

– Provide more intuitive views than traditional projection, e.g., polar routes

Planetary Science

• International 10-week 10th-grade curriculum on the origin of life developed via Space Act agreement with Australia & the U.K.

• NASA Earth Science curriculum development

Education Significance

Humanitarian Significance

• UN Division of Early Warning and Assessment– World health, agricultural support,

drought forecast, etc.

• US Agency for International Development– SERVIR MesoAmerica Project

• World Wind used at the presidential decision-making level for Costa Rica and Panama regarding the Sixaola River, their international border, where flooding caused the ‘border’ to change.

International Significance

Press

International computer magazines: Germany, Poland, Greece, Italy, China, Japan, Hungary, Netherlands, U.K., Spain, etc.

Total Use

• >100,000 new unique IPs per week

• >1 million downloads a month

• >100 requests for imagery per second

Open Source Benefits
