WorldWindJS

Important News

Mitigation efforts are underway to ensure that WorldWindJS based projects are insulated from the effects of the NASA WorldWind project suspension.

A community supported and enhanced Web WorldWind library

WorldWindJS is a fork of the popular Web WorldWind library from NASA (with contributions from ESA). This fork provides a release channel for builds based on the latest fixes and features from WebWorldWind's develop branch plus several "cherry-picked" enhancements from the WorldWind community.

This fork exists to support the development of several personal projects, including:

• Explorer - the WorldWind Explorer
• WMT v2.0 - Wildfire Management Tool v2.0 (under development)
• Bible Atlas - Geography and cartography of the Holy Land (under development)
• worldwind-react-globe - A React component for Web WorldWind
• worldwind-react-globe-bs4 - React Bootstrap4 UI components for Web WorldWind
• worldwind-react-app - A geo-browser web app using Web WorldWind with React and Bootstrap 4

WorldWindJS is made available in the spirit of the NASA motto: For the benefit of all. Show your support for this project by giving it a star!

Enhancements include:

• A template for creating geo-browser web apps with Bootstrap and Knockout (apps/worldwind-app-template).
• Keyboard navigation controls for the globe
• Improved the resolution of Bing imagery
• Support for a translucent night-image
• Removed dependency vulnerabilities
• Fixed WMTS tile geo-registration

Migrating from NASA WebWorldWind

• The WorldWindJS npm package is available in the npm repository.
• WorldWindJS is available on the unpkg and jsDelivr CDNs. See CDN providers in the wiki for examples.
• The project supports npm dependencies on its git repository: See npm dependencies in the wiki for examples.
• The JS libraries (production and debug) and the image resources are available in the GitHub releases.

Changes from WebWorldWind release 0.9.0

• NavigatorState has been deprecated. Its properties have migrated to DrawContext.
• Added the HeatMap from the WorldWind NASAWorldWind/feature/heatmap branch.
• Added the ShapeEditor from the WorldWind NASAWorldWind/enhancement/shape_editor_refactoring branch.

Changes from the WebWorldWind develop branch

• WorldWindJS is a drop in replacement for WebWorldWind's worldwind.js and worldwind.min.js libraries built from the WebWorldWind develop branch. There are no changes to the API other than additions.

Web WorldWind

Web WorldWind is a 3D planetary globe engine built in JavaScript for the web, developed by NASA. The European Space Agency has provided valuable contributions to this platform since 2015. Web WorldWind provides a geographic context complete with terrain, and a collection for shapes for displaying and interacting with geographic or geo-located information in 3D and 2D in any modern web browser. High-resolution terrain and imagery is retrieved from remote servers automatically as needed, while enabling developers to include their own custom terrain, imagery, 3D shapes, and position markings.

The project's website, worldwind.arc.nasa.gov has setup instructions, developer guides, API documentation and more.

Get Started

The Web WorldWind Developer's Guide has a complete description of Web WorldWind's functionality. In there, you will find many Web WorldWind resources, including a user guide and documentation for every module file. For complete beginners on WorldWind, the Get Started tutorial is the place to go.

The latest Web WorldWind release provides many simple examples showing how to use most of Web WorldWind's functionality, as well as more involved small applications for reference on how to use Web WorldWind in domain-focused GIS development.

Building

Install NodeJS. The build is known to work with Node.js 12.18.0 LTS.

• npm install downloads WorldWind's dependencies and builds everything

• npm run build builds everything

• npm run doc generates the WorldWind API documentation

• npm run test runs WorldWind's unit tests

• npm run test:watch automatically runs WorldWind's unit tests when source code changes

• npm version <newversioo> changes the version number in package.json

• npm publish publishes the build to npm
