World Wind can be expanded by using one of many add-ons - small extensions that add new functionality to the program. Many people using the applications are adding their own data and are making them available through various sources, such as the World Wind Central or blogs mentioned in the link section below.Īll images and movies created with World Wind using Blue Marble, Landsat, or USGS public domain data can be freely modified, re-distributed, and used on web sites, even for commercial purposes. In addition, WW has bathymetry data which allows users to see ocean features, such as trenches and ridges, in 3D. This means one can view topographic features such as the Grand Canyon or Mount Everest in three dimensions. World Wind uses digital elevation model (DEM) data collected by NASA's Shuttle Radar Topography Mission (SRTM), National Elevation Dataset (NED) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). Microsoft has allowed World Wind to incorporate Virtual Earth high resolution data for non-commercial use. The resolution outside the US is at least 15 meters per pixel. The resolution inside the US is high enough to clearly discern individual buildings, houses, cars (USGS Digital Ortho layer) and even the shadows of people (metropolitan areas in USGS Urban Ortho layer). X ( DirectX 3D polygon mesh) models and advanced visual effects such as atmospheric scattering or sun shading. Other features of World Wind.NET included support for. This is an example of how World Wind allows anyone to deliver their data. World Wind.NET provided the ability to browse maps and geospatial data on the internet using the OGC's WMS servers (version 1.4 also uses WFS for downloading place names), import ESRI shapefiles and kml/kmz files. Five million place names, political boundaries, latitude/longitude lines, and other data can be displayed. Users could interact with the selected planet by rotating it, tilting the view, and zooming in and out. All these worlds are available in the File menu. Apart from the Earth there are several worlds: Moon, Mars, Venus, Jupiter (with the four Galilean moons of Io, Ganymede, Europa and Callisto) and SDSS (imagery of stars and galaxies). NET-based version was an application with an extensive suite of plugins. The latest Java-based version (2.0), was released in April 2014.
NASA WORLD WIND TUTORIAL LICENSE
Though widely available since 2003, World Wind was released with the NASA Open Source Agreement license in 2004. The program overlays NASA and USGS satellite imagery, aerial photography, topographic maps, Keyhole Markup Language (KML) and Collada files.
NASA WORLD WIND TUTORIAL SOFTWARE
The World Wind Java version was awarded NASA Software of the Year in November 2009. The SDK includes a suite of basic demos, available at. NET version, not a standalone virtual globe application in the style of Google Earth. The more recent Java version, World Wind Java, is cross platform, a software development kit (SDK) aimed at developers and, unlike the old. NET Framework, which ran only on Microsoft Windows. World Wind, with 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.
