The Fuji in World Wind

NASA World Wind is an open source - software for satellite and aerial images . The software makes it possible to display these images combined with elevation data on a virtual globe . It is possible to zoom in on any place on earth in 3D graphics and view it from all sides. The software was released in autumn 2004 under the free "NASA Open Source license v1.3". The image data was originally based primarily on the Landsat program.

The program also has extensive map material for the moon , Mars , Venus and Jupiter .

The further development and operation of World Wind were temporarily interrupted in May 2019.

Versions

application

An installable application from World Wind is available for Windows and Linux . DirectX and the .NET Framework are required for the installation .

The application offers various options for displaying your own data. There are functions to open KML and shapefiles as well as to integrate Web Map Services and Web Feature Services .

Extensions

NASA World Wind includes an open interface so that you can develop your own plug-ins . Add-ons expand World Wind with new models, additional image material and new functionalities. Typical examples are:

  • Points of Interest and Itineraries
  • Place names
  • High-resolution aerial and satellite images of selected areas
  • Interface to GPS receivers
  • Import of selected file formats

Java SDK

On May 8th, 2007 NASA released a Java Software Development Kit based on OpenGL . With this SDK, developers can use World Wind technology in their own, platform-independent applications.

Available records

NASA World Wind comprises models (so-called worlds ) and extensive images of the earth, the moon and selected planets. A total of approximately 4.6 terabytes of data is currently made available. They are continuously reloaded by NASA servers when a region of the world is to be displayed in more detail.

Coordinate linking

Tenerife from the west, with NASA World Wind

With the help of the worldwind: // scheme it is possible to specify any coordinates on the earth's surface as a reference. The following example shows a coordinate point in Lake Constance .

worldwind: //goto/world=Earth&lat=47.596363067627&lon=9.44736003875732&view=1.35181939601898
