NASA World Wind
World Wind是一套有趣的程式，大約260MB，透過這套程式的3D引擎，可以讓你從外太空看見地球上的任何一個角落。
結合線上的資料庫，World Wind最高的解析度可以達到每像素代表15公尺，也就是說一些比較大的街道可以看得一清二楚，而且包含除了可見光以外的影像。
此外，透過其中的功能，你可以進行一趟地球的3D飛行之旅，體驗飛過聖母峰的感覺。
另外，透過即時動畫形成的模組，你可以即時體驗颶風如何席捲佛羅里達州，或是氣候的變化情況。
另外一個模組可以即時顯示目前地球上發生的火災、空氣污染等等資訊。
此外，各國天氣與國界分布，當然都可以輕而易舉的取得。
注意，這套程式需要較好的電腦設備，下載前請參考下面的系統需求：

World Wind Notes
World Wind benefits most from a video card with 3d acceleration. If you don't know your machine comes with one, it is likely to have one built in if the machine was purchased within the past two years.
World Wind requires DirectX 9b and the .NET Runtime environment to be installed. These have been included in the World Wind installer
World Wind comes with a certain amount of data you can zoom into. After a certain point, World Wind will begin to download more images automatically.
At this point, your Internet connection can make a big difference
