This application demonstrates JWAVE's ability to process large amounts of live data in the form of global weather information and ship locations at sea. This JWAVE demo allows personnel onboard ocean-going vessels to retrieve information in their Web browser and illustrates how JWAVE can be used to create and distribute visual data analysis applications.

The application shows a map of the Earth. You can view the position of ships in the fleet, wind direction, atmospheric pressure and tropical storms. You can manually enter the center latitude and longitude you wish to view or you can click on the map to set these fields interactively. You can zoom in and out to see different areas of the map and have it drawn from multiple projections.

Directions

1. Click on the map to select the point you wish to view or manually enter the longitude and latitude by typing them in the Mapping text fields.
2. You can zoom in and out by typing in a number from 0 to 50 in the Zoom Factor text field. (0 is the entire globe and 50 zooms in the closest.)
3. Select the projection you want from the Projection pull-down menu. (Note: You will not be able to interact with the map if you select the Satellite projection.)
4. Select what you wish to view -- air pressure contours, wind velocity vectors, tropical storm icons, and fleet ship position information -- by checking the appropriate check box.
5. If the Tropical check box is selected and the map updated, clicking on a tropical storm icon displays detailed information about the storm, position, path and strength. (There is a storm displayed between Iraq and Iran.)
6. If the Position toggle is selected, the location and four-letter abbreviation for each ship in the fleet is displayed. If the button is deselected, no ship positions will be displayed, but you will be able to select individual ships in the tab view to the right.
7. Press the Plot button to update the display based on the selections you made.
