Requirements


Displays the default globe with its default layers. Includes capabilities such as a compass and status bar that are common to most applications, and presents Earth within a star field and with an atmosphere. Only 6 lines of code are required to instantiate everything seen here.


Demonstrates loading, displaying, and interacting with KML content in WorldWind.


Features a WMS layer panel that allows you to access any WMS server and layers.

To add a server, click on the + tab and enter a url. After the WMS discovery process, the list of available layers is displayed. Select one to add it to the current globe layer list. Unselect it to remove it.


Enables a user to install image data and elevation data from a file on the local hard drive. Data can be installed as a full pyramid of tiles or as a partial pyramid.

Installing a full pyramid takes longer and consumes more space on the user’s hard drive, but has the best runtime performance. Installing a partial pyramid takes less time and consumes less space on the user’s hard drive, but requires that the original data not be moved or deleted.


Demonstrates how to use the SectorSelector utility to save a selected region of surface imagery and elevations to a GeoTIFF file.


Demonstrates high resolution imagery (0.2 meters per pixel) and elevation data (1.6 meters per pixel) served by the WorldWind WMS, and visualized by the WorldWind Java client.


Demonstrates visualization of common rigid shape types in WorldWind Java. Includes six rigid shape types: Box, Cone, Cylinder, Ellipsoid/Sphere, Pyramid, and Wedge.


Shows visualization of textured 3D buildings with WorldWind Java SDK Extruded Shapes.


Demonstrates visualization of common terrain following shapes in WorldWind Java. Includes five surface shape types: SurfacePolyline, SurfaceQuad/SurfaceSquare, SurfaceEllipse/SurfaceCircle, SurfaceSector, and SurfacePolygon.


Demonstrates the WorldWind Java controlled airspaces tookit.

Airspaces feature 3D volumes controlled by geographic coordinates and upper- and lower- altitude boundaries. Airspaces optionally conform to the terrain as you move them. They demonstrate what’s possible in terms of dynamic manipulation of data in 3D space.


Demonstrates visual representation of scalar values over a grid of geographic positions. AnalyticSurface supports dynamic scalar data by providing a simple, high throughput rendering pipeline for the application.

This demonstrates two unique surface types:

  • A dynamic surface representing random altitudes over the Coast of Florida, USA.
  • A static surface representing annual precipitation in Washington State, USA.

Illustrates how applications can display video on the globe’s surface.


Demonstrates use of WorldWind browser balloons to display HTML, JavaScript, and Flash content to the user in the form of a screen-aligned balloon. There are two browser balloon types: ScreenBrowserBalloon which displays a balloon at a point on the screen, and GlobeBrowserBalloon which displays a balloon attached to a position on the Globe.


Allows you to experiment with the multiple options of WorldWind Java annotation feature.

Annotations are text labels with support for multiline text, simple HTML and many styling attributes such as font face, size and colors, bubble shapes and background image.


Demonstrates the use of WorldWind annotations to create simple user interfaces embedded into the WorldWindow.


Shows visualization of the Military Grid Reference System (MGRS) as a graticule overlayed on the globe’s surface.


Shows the terrain profile layer in action with its various controls. Allows a view of a realtime section profile graph for any place on the planet, at any scale - continent, country or mountain range… just by moving the mouse.

It proves particularly useful to explore the ocean floors where the bathymetry data reveals important geologic features.


Shows the latest earthquakes over a flat world projection. Allows you to see the whole globe at once while retaining the capability to zoom onto the surface and still experience 3D terrain.


Shows anaglyph stereo viewing capability. It allows you to explore the world in ‘real’ 3D using red and cyan glasses with the red filter over the left eye.

To get a comfortable experience use the slider to adjust the interocular distance.


Demonstrates WorldWind Java SDK support for rendering globes in multiple application windows. WorldWind automatically shares resources wherever possible across multiple windows in a single runtime environment.


Demonstrates how applications can keep a set of moving objects in view.


Allows you to interactively draw a path over the terrain surface.

It demonstrates how an application can use and consume mouse events before they get to the default view input handler.


Demonstrates runtime construction of 3D shapes using the WorldWind Java controlled airspace shapes.

  • New shape - Click the “New shape” button. When “Auto fill new shapes” is checked a default shape is created automatically
  • Select a shape - Left mouse button click
  • Delete a shape - Select the shape, then press the delete key.
  • Move a shape or move a control point - Drag the shape or control point with the left mouse button
  • Resize a shape - Hold the Shift key and drag any control point with the left mouse button
  • Create a control point - Hold the Alt key and click the left mouse button
  • Delete a control point - Hold the Ctrl key and click the left mouse button

User Created Application Examples


GLIDER (Globally Leveraged Integrated Data Explorer for Research) is a NASA ACESS funded project managed at UAHuntsville ITSC. The goal of this project is to integrate three existing applications, namely WorldWind, Interactive Visualizer and Image Classifier (IVICS) and the Algorithm Development and Mining (ADaM) toolkit into a single seamless tool for research and education community. GLIDER will be a complete comprehensive, easy to use tool for thematic information extraction from NASA imagery.


ESA EOLi (Earth Observation Link) is the European Space Agency’s client for Earth Observation Catalogue and Ordering Services.

Using EOLi, you can browse the metadata and preview images of Earth Observation data acquired by the satellites ENVISAT, ERS, Landsat, IKONOS, DMC, ALOS, SPOT, Kompsat, Proba, JERS, IRS, Nimbus, NOAA, SCISAT, SeaStar, Terra/Aqua.

By default, EOLi-sa uses a 2d drawing mode. To enable WorldWind, click on the layered map icon in the upper right for map settings. Then choose Orthographic or Plate Carrée (new 3D map) for a projection.


‘Fly’ an F-16 and immerse yourself in the cockpit as it maneuvers over the terrain. All made possible through a collaboration between NASA WorldWind, Oracle and DiSTI. Here together you’ll see these three powerful technologies—NASA’s WorldWind, Oracle’s Java Open GL and DiSTI’s new GL Studio for Java—converge to enable Java developers to leverage spatial data in a 4D world with incredible virtual reality.

JSatTrak is a Satellite tracking program written in Java. It allows you to predict the position of any satellite in real time or in the past or future. It uses advanced SGP4/SDP4 algorithms developed by NASA/NORAD to propagate the satellite orbits.

The program also allows for easy updating of current satellite tracking data via CelesTrak.com. Because this application was written in Java, it should run on almost any operating system or directly off the web using java web start!

Version 3.0 requires Java 1.6 - and uses NASA’s WorldWind Java SDK (included) and JOGL for 3D rendering (included for win).
