The applications and applets here demonstrate some of World Wind’s rich capabilities. Also see World Wind Europa Challenge site for a collection of applications created by the World Wind Europa Challenge teams.
World Wind demos applications and applets require Java 7 update 13 or later.
World Wind Demo Applications
This is the most basic usage of the SDK. It displays the default globe with its default layers. It 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. It requires only 6 lines of code to instantiate everything seen here.

Demonstrates loading, displaying, and interacting with KML content in World Wind.
> KMLViewer.jnlp – launch with Java Web Start.
WMS Layer Manager
This example application demonstrates the SDK WMS capabilities. It 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 the server url. After the WMS discovery process, the list of available layers will be displayed. Select one to add it to the current globe layer list. Unselect it to remove it.
> WMSLayerManager.jnlp – launch with Java Web Start.
Installing Images and Elevations
The World Wind Java Installing Imagery And Elevations Demo enables a user to install image data and elevation data from a file on the local hard drive. This 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.

GLIDER – Globally Leveraged integrated data explorer for research
GLIDER (Globally Leveraged Integrated Data Explorer for Research) is a NASA ACESS funded project. The goal of this project is to integrate three existing applications, namely World Wind, 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.

Media Watch on Climate Change – Knowledge Planet
“The Knowledge Planet applet shows that virtual globes are not only suited to explore geographic maps, but can also serve as rendering engines for other types of imagery. It visualizes large document collections using a landscape metaphor. The peaks of the virtual landscape indicate abundant coverage on a particular topic, whereas valleys and oceans represent sparsely populated parts of the information space.”
“The Media Watch on Climate Change is developed as part of the IDIOM (Information Diffusion across Interactive Online Media) research project. The consortium partners behind the project share an interest in the determinants and impacts of anthropogenic climate change, and in the potential of three-dimensional interface technology to support communication and collaboration in virtual communities.”
