WorldWind is a free, open source API for a virtual globe. WorldWind allows developers to quickly and easily create interactive visualizations of 3D globe, map and geographical information. Organizations across the world use WorldWind to monitor weather patterns, visualize cities and terrain, track vehicle movement, analyze geospatial data, and educate people about the Earth.
Because WorldWind is completely open source, extending the API is simple and easy to do. This creates a powerful platform for giving any application the means to express, manipulate and analyze spatial data. WorldWind technology can be incorporated into a wide range of applications, including Windows, Mac, Linux, web, and mobile devices.
WorldWind is different from a 3D globe like Google Earth because it is not an application. Instead, it is an SDK (software development kit) that software engineers can use to build their own applications. WorldWind provides a geographic rendering engine for powering a wide range of projects, from satellite tracking systems to flight simulators.
With WorldWind handling the hard work of visualizing geographic data (generating terrain from elevation models, selecting and displaying images from imagery servers, etc), software engineers are free to focus on solving the problems specific to their own domains and quickly building whatever geospatial applications they choose.
Develop a world-class WorldWind application for your Android phone or tablet. Instructions, tutorials, and examples are available on the project's home page. The WorldWind Android GitHub repository contains the library and code.
WorldWind's source code, official releases, engineering roadmap, issue tracking and more are hosted by GitHub and managed by the NASA WorldWind development team.
