This means one can view topographic features such as the Grand Canyon or Mount Everest in three dimensions. WorldWind 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 WorldWind 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 WorldWind.NET included support for. This is an example of how WorldWind allows anyone to deliver their data. WorldWind.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.

As of 2017, a web-based version of WorldWind is available online. Organizations around the world use WorldWind to monitor weather patterns, visualize cities and terrain, track vehicle movement, analyze geospatial data and educate humanity about the Earth." It was first developed by NASA in 2003 for use on personal computers and then further developed in concert with the open source community since 2004. WorldWind allows developers to quickly and easily create interactive visualizations of 3D globe, map and geographical information. According to the website ( ), "WorldWind is an open source virtual globe API. NASA WorldWind is an open-source (released under the NOSA license and the Apache 2.0 license) virtual globe.
