NASA World Wind（有直译为世界风者），是NASA发布的一个开放源代码的地理科普软件，由NASA Research开发，NASA Learning Technologies来发展，它是一个可视化地球仪，将NASA、USGS以及其它WMS服务商提供的图像通过一个三维的地球模型展现，近期还包含了火星和月球的展现。

用户可在所观察的行星上随意地旋转、放大、缩小，同时可以看到地名和行政区划。软件还包含了一个软件包，能够浏览地图及其它由因特网上的OpenGIS Web Mapping Service提供的图像。

World Wind is an open-source (released under the NOSA license) virtual globe first developed by NASA in 2003 for use on personal computers and then further developed in concert with the open source community since 2004. The original version relied on .NET Framework, which ran only on Microsoft Windows. The more recent Java version, World Wind Java, is cross platform, a software development kit (SDK) aimed at developers and, unlike the old .NET version, not a standalone virtual globe application in the style of Google Earth. The SDK includes a suite of basic demos, available at goworldwind.org. The World Wind Java version was awarded NASA Software of the Year in November 2009. The program overlays NASA and USGS satellite imagery, aerial photography, topographic maps, Keyhole Markup Language (KML) and Collada files.
