“UNAVCO Rules” Ruler details

The "UNAVCO Rules" Ruler is a lenticular ruler which shifts images at it rotates. This ruler has four images showing: the UNAVCO logo with the "Face of the Earth" image, gps plate motions, earthquakes, and plate boundary strain rates.

Jules Verne Voyager is a high-precision, interactive map visualization tool designed to help scientists, educators, and students study global-scale geodynamic processes and visualize the relationships between and among processes, natural Earth structures, and features (faults, earthquakes, and volcanoes, etc.), and science measurements (GPS plate motion data, etc.).

Voyager works equally well for visualizing other planets and moons, and we are collecting a set of data for most major bodies of the Solar System. See our Solar System Portal or the Jules homepage menu for current links.

With this Java-based tool, users can view a variety of base maps including satellite mosaics, topography, geoid, sea-floor age, and strain rate. Because Jules Verne Voyager generates a map from the data for each request, this tool is appropriate for researchers and individuals who have the time to wait for the server to generate the map and transmit it to the user.

Also available are geographic and geophysical overlays such as political boundaries, rivers and lakes, National Earthquake and Information Center earthquake and volcano locations, stress axes, and observed and modeled plate motion and deformation velocity vectors representing a compilation of 2933 geodetic measurements from around the world.

Create Your Own Map!

For teachers, students, and others who want to explore earthquake and volcano locations, GPS data, the age of the ocean floors and other data, we have two tools for you: Jules Verne Voyager, Jr., which provides a world view, and EarthScope Voyager, Jr. which provides a closer look at selected areas of the United States. A list of these tools is available on UNAVO's Education and Outreach Jules Verne Voyager Map Tools page.

Ruler image details

Image 1:
This image is from the dataset taken from the Earth edition of Jules Verne Voyager is ARC Science Simulations' "Face of the Earth" image which shows the Earth's surface in natural colors with atmospheric bluing removed.

Image 2:
The vector arrows are plate motion velocities determined from GPS data at selected IGS sites around the world in a "no-net-rotation" reference frame called ITRF2000; see also UNAVCO's GPS Site Motion Vector/Crustal Velocity Archive.

Image 3:
This image shows of 40 years of NEIC earthquake hypocenters. The depth of the events is indicated by color:
green = shallow, magenta = very deep; see Jules VerneVoyager Earthquake Depth page for more details.

Image 4:
The dataset shown in this image is from the Global Strain Rate Map Project. It shows the "magnitude" of the lithospheric strain rate as the 2nd invariant of the model's strain rate tensor, demonstrating that the zone of deformation at plate boundaries can be quite broad. The colors indicate the magnitude of the strain rate:
magenta = very high strain rates, blue = very low strain rates; see Jules VerneVoyager Global Strain Rate Ancillary Information page for more details. For more information on strain, visit the Strain Rate Models Archive
