The Jules Verne Voyager Jr. is an interactive map tool developed by the UNAVCO Facility with support from the National Science Foundation for the study of global-scale geodynamic processes. The imagery is taken from the Earth and ILP_GSRM bodies of Jules Verne Voyager, a map-making tool that uses the Generic Mapping Tool kit (GMT). JVV Jr. credit and contact information is at the bottom of this page.
This page provides an overview of how to use the JVV Jr. It also describes the buttons in the JVV Jr. box on the left (Info/Help, To Education Site, Legend On/Off, World Map, Smaller/Bigger Maps, Zoom Out and Make Changes). You can access this help system by clicking on any of the menu buttons at the top of the screen or the Intro/Help button. Note that the site is under development and will be updated as new features and information are added.
You can change the map display by clicking on one or more items in the base map, features, and velocities list boxes. Then click on the map for the new display in a different region or click the Make Changes button to remain in the current region.
Base Maps: The JVV Jr. opens with a map of the world displayed. You can change the map by selecting another map in the Select a Base Map list box. Once a map is selected, a thumbnail view will display to the right. If you preview a number of maps, be sure that the one you want to view is highlighted at the end. For more information on the maps, access the Select a Base Map page above.
Add Feature(s): You can add one or more features by holding down
the CTRL key on PCs or the Command key on Macs and clicking on several features.
To deselect a feature, click on the highlighted item again. If you only
have one feature selected, click on No Features to deselect it. Note that
the feature will appear on all subsequent maps until deselected. For more
information on the features, access the Add Features
Add Velocities: You can overlay velocities on your base map, showing the direction and rate of plate movement. First, select a plate in relation to which the velocities will be drawn. Then, select the type of data to be displayed (model, observational, or both). Note that in browsers other than Netscape 4x, the data types will not display until you have selected a plate. To change your selections, choose another item in the list box or click on No Plate Velocities to turn them off. Click on the radio buttons to switch between Model, Observational, or both types of data. Note that the velocities will appear on all subsequent maps until deselected. For more information on the velocities, access the Add Velocities page above.
Make Changes: Click this button to view the current region with the new map and overlays you have selected.
Zooming In: Click directly on the map to zoom in. Three zoom levels are currently available. Clicking near the edge of the map may take you to a neighboring region rather than zooming in to the current region.
Zoom Out: Once you have zoomed in on a world map, clicking on the Zoom Out button will take you out (up) a level.
World Map: This button displays the orignal map of the whole earth with the selected base map, features and velocities still displayed.
Legend On/Off: This button turns the legend window on or off. The legend window shows your current selections and has an interpretive key for each base map, feature, and velocity selected. The information updates whenever a new map is displayed.
Smaller/Bigger Maps: The maps are available in two sizes; clicking on this button toggles between them. (The smaller set is intended for those with small monitors or slow internet connections.)
To Education Site: This button links to the Exploring Our Dynamic Planet website with curriculum and other materials related to exploration of the JVV Jr. imagery and GPS. The first unit is on measuring plate tectonics and is designed for high school and undergraduate Earth science courses.
Info/Help: The Info/Help button opens the JVV Jr. help window to this introductory page. To access the other help pages, either click on the buttons at the top of this page, or the buttons at the top of the main JVV Jr. window (Select a Base Map, etc.).
Printing the maps: To print a map, click on the Print link. This will up a new window with an image of the map alone. This will take several seconds, so be patient. Once the image loads, select File->Print from your browser.
