Features include, 3D virtual globe, 2D map with multiple projection choices (Mercator, Polar, UPS, Equirectangular), imagery and elevation import, extensible, data retrieval (via REST, WMS, WCS, WFS, Bing, User-Defined), decluttering, measurement, accurate line-ofsight, subsurface visualization, and more. Web WorldWind runs on any platform via a browser, i.e., Internet Explorer, Firefox, Chrome and Safari. WebWorldWind also provides platform independence, while accommodating any number of data types. It is written in JavaScript and provides the real world geographic context for spatial data and information visualization, using a rich set of shapes and graphic primitives. WebWorldWind is an application component, not an app in itself. Apps built with this web version are ideal for immediate social media type activity and also facilitate delivery of sophisticated data exchange scenarios such as weather and climate research, disaster response, personal navigation, and industrial-strength tracking for transportation, supply chain, aviation and satellites. The web version of NASA WorldWind (WebWorldWind) has made it possible for a whole new suite of applications for managing and sharing spatial data. This allows you to provide maximum value of the information to your user community. You decide how the data is accessed and experienced. Unlike other virtual globes such as Google Earth, NASA World Wind offers something very special, full control to customize the interface with any features or functionalities you might need. For developers, by simply updating the app on your server, the latest version of your application is now immediately available to your entire usercommunity. Without the need to install an application, spatial data can now be experienced via any web browser, mobile devices included. ![]() Recently, the accessibility of spatial data has dramatically improved. This presentation will demonstrate several NASA open source use cases for WorldWind technology that include advances being made to optimize access to NetCDF and HDF data via WebWorldWind.NASA WorldWind: Multidimensional Geospatial Web Platform The ability to see spatial data in its native context is essential for that data to be appreciated whether by the scientific community, policy and decision-makers or the general public. Federal Aviation Administration, FAA, uses WorldWind, as do applications currently being developed by the European Space Agency, along with several other US and European government agencies and industry partners. Illustrates how to import data from a Vector Product Format (VPF) database into World Wind. This example demonstrates how to look around a scene by controlling the views pitch, heading, roll and field of view, in this case by using a simple set of sliders. ![]() The next-generation National Airspace System (NAS) aviation management system for the U.S. Example of how to keep the view within certain bounds. This enable it to be continually optimized and feature-enriched in ways that allow applications based on this SDK (Software Development Kit) to benefit Earth Observation, especially Open Science, with minimal or no adjustment for the decade ahead. NASA World Wind: virtual globe for an open smart city.NASA WorldWind: Open Source Visualization Technology for Earth Observation NASA WorldWind: Open Source Visualization Technology for Earth Observation WorldWind, open source virtual globe technology for Java, iOS, Android and Web, is provided by NASA and is architected as API-centric modular componentry. ![]() Cite this article Brovelli MA, Kilsedar CE, Hogan PJ, Prestifilippo G, Zamboni G.
