Blue Marble Twelve Month

This example application gives you access to the twelve month of the Blue Marble Next Generation dataset for the year 2004.

It also lets you play an animation of the full twelve month cycle, showing how the Earth face changes over the year, as seen from space.

> BMNGTwelveMonth.jnlp - launch with Java Web Start.

World Wind Web Service Catalogs

The World Wind Web Service Catalogs application provides easy access to geospatial imagery via web service catalogs. NASA's Earth Science Gateway catalog, and the Naval Research Laboratory's Geospatial Information Database (GIDB) Portal System are included as examples.

This application utilizes OGC Catalog Service support built into World Wind Java.

> WorldWindCatalogs.jnlp - launch with Java Web Start.

Cascade Volcanoes Tour Applet

This page shows a World Wind applet controlled from HTML hyperlinks in the page body text.

In this example all the specific elements - text labels and view positions, are controlled from the HTML and Javascript code within the page. The same java applet could be used for many other purposes without any change.

Javascript Location-marks Applet

This page allows you to save the view current location into a list of favorite places.

When double clicking on a location in the list, the view is sent flying to the position and angle it had when you saved that location. The list is saved into a permanent cookie on the local computer and will be retreived the next time you come back.

Air Search And Rescue

This application helps search and rescue planners determine the best places to search after a plane goes missing.

Using last known positions from ground radar and other sources, planners are able to reconstruct an aircraft path and study it's position relative to the ground from any view point including that of the pilote.
