ESA-NASA Web World Wind is a free, open source API for a virtual globe. World Wind allows developers to quickly and easily create interactive visualizations with a 3D globe for mapping geographical information. https://nasaworldwind.github.io/
Organizations around the world use World Wind to monitor weather patterns, visualize cities and terrain, track the movement of planes, vehicles and ships, analyze geospatial data, and stated simply, educate people about the dynamic nature of life on Earth. The features and benefits of ESA-NASA Web World Wind are straightforward and rich. World Wind is fully open source, therefore extending the API is simple and easy to do. Developers can create powerful platforms that give any application the means to express, manipulate and analyze spatial data. World Wind technology can be incorporated into Windows, Mac, Android and Linux applications, via web pages and web applications, as well as mobile applications alike. Build whatever virtual globe app you want.
ESA-NASA Web World Wind is different from other 3D globes like Google Earth because it is not a completed application targeted at end-users. Instead, it is an SDK (Software Development Kit) that software engineers can use to build their own applications. The SDK contains the World Wind API, examples and demos. The API provides the virtual globe. Examples and demos show how to use World Wind code in order to create a wide range of web apps, from satellite tracking systems to flight simulators.
World Wind takes care of the heavy-lifting for visualizing geographic data (generating terrain from elevation models, selecting and displaying images from imagery servers, etc), software engineers are free to focus on solving problems specific to their own domains and quickly build whatever geospatial applications they choose.

Web WorldWind is a partner of EarthServer-2 and provides a frontend engine to all its services (http://earthserver.eu/services). Large datasets ingested in rasdaman and queried via OGC standards such as Web Coverage Service (WCS) and Web Coverage Processing Service (WCPS) are easily visualised on a globe, regardless of where you are in the Solar System, whether on Earth, the Moon or Mars.
The Earth Observation Data Service - http://eodataservice.org - is one of the EarthServer-2 services that provides efficient and fast extraction from large volumes of spatio-temporal datacubes as well as on-the-fly processing capabilities: discovery, access, visualization and download tools are made available on top of the 3D virtual globe powered by ESA-NASA Web World Wind, the natural environment where the Earth Scientists find easy-to-use service functionalities to dynamically interact with Earth Observation products.
A large variety of EO products observed by satellite instruments operated by the European Space Agency (ESA) and National Aeronautics and Space Administration (NASA), as well as Essential Climate Variable (ECV) developed under international initiatives (Climate Change Initiative, Global Climate Observing System, Global Precipitation Climatology Project, ...) are available to provide an empirical basis for understanding past, current, and possible future climate variability and change.
You can join the EO Data Service community and see how easy and fast it is to support applications for pollution monitoring, weather, agricolture, ocean, climate health, land cover analysis.
For out-of-this-world applications of WebWorldWind and EarthServer/rasdaman technology, you can check PlanetServer, the Planetary Science Data Service of EarthServer. A description of its features is available here. All the code of PlanetServer is openly available on https://github.com/planetserver.
