Jules Verne Voyager Jr. Introduction

The JVV Jr. is an interactive map tool developed by UNAVCO with support from NASA and the National Science Foundation for the study of global-scale geodynamic processes. The imagery is taken from the Jules Verne Voyager, a map-making tool that uses the Generic Mapping Tool kit (GMT). JVV Jr. credit and copyright information is listed 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, Big / small maps, Print / save, World Map, See in JVV, 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 updated periodically as new features and information are added.


Getting started...

You can change the map display by clicking on one or more items in the base map, features, and velocities list boxes.

Make changes: Once you've made your selections, you must click on the Make Changes button to activate them. (Pressing the Enter key may work on some systems.)

Zooming on: You can zoom in on an image by clicking directly on it. Four zoom levels are currently available. Clicking near the edge of the map may pan to a neighboring region instead of zooming in.

Zoom out: Once you have zoomed in on a world map, click on the Zoom Out button to move out (up) a level.

Panning: Clicking near the edge of the map may pan to (move you to) a neighboring region.

World map: This button redisplays the world view of the map that you have chosen, with the selected features and velocities still displayed.

Legend on / off: This button opens the Legend window, which displays your curent selections and has an interpretative legend for each selection. The information updates whenever a new map is displayed. Clicking on the Legend On/Off button opens or closes the Legend window.

Big / small maps: The maps come in two sizes, the default being the larger size. (The smaller version is intended for those with smaller monitors or slow internet connections. )

See in JVV: Clicking this buttons displays the current map and overlays in the Jules Verne Voyager, the high precision interactive map tool developed by UNAVCO, from which the JVV Jr. imagery was taken. Voyager was developed to help scientists better visualize the inter-relationships of geophysical and geologic processes, structures, and measurements with high-precision GPS monument data and solutions on Earth. It has since been extended to include other planets and moons and is expected to have data for most major bodies of the Solar System.

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: This button opens this Overview page. You can access the other sections by clicking on the buttons at the top of this window or the main JVV Jr. window.

Printing / save: This button allows you to save and print the map currently displayed. The map will open in its own window. (Be patient as this can take several seconds.) Once the image loads, select File, then Print from your browser.
