Data for the strain image display is on the UNAVCO Catalog:
In the IDV use menu choice Data->New Data Source->From a Catalog. Enter at Catalogs:
http://geon.unavco.org/unavco/catalog.xml
Click on the button left of "Global Strain Rate Map Project Data (GSRM)." In the list that appears click on the item "Europe plate reference frame global velocity vectors" and click the "Add Source" button. Repeat with item "GSRM global strain grid" (the strain rate grid for an image).

Bundle file to load strain grid and vectors, and make this display.

The Global Strain Rate Map (GSRM) data is provided by Corne Kreemer.

Data provided by R. L. Smith, University of Utah; ; see University of Utah Publications on Geophysical and Geological Studies of the Yellowstone Hotspot and the Yellowstone Volcanic System and Surrounding Area.

You can plot the location of volcanos and this week's earthquakes using the main menu commands
"Displays -> Locations -> Earth -> Earthquakes" and
"Displays -> Locations -> Earth -> Volcanos." Display controls let you change point symbols, colors, and plot density (cluttering) as usual. The earthquake lable lists magnitude; in the display control's "Locations" tab you can see depths listed, and in the "Selected" tab panel you can see more data about an earthquake including a web link to the USGS Earthquake Center data page for that event.

The volcano data is from the Smithsonian Global Volcanism Progam, http://www.volcano.si.edu. In the display control's "Locations" tab you can see all numerical data, and in the "Selected" tab panel you can read all about a volcano, including a photograph.

The sample image to the left (click for full size) also has the JPL "Blue Marble" earthsurface image (see next).

You can select and display many data sets available online via WMS web map servers. In the Dashboard "Data Chooser" select "catalogs" and enter
http://www.unidata.ucar.edu/georesources/idvcatalog.xml
Explore the many choices got by clicking "Web Map Servers." There are the JPL "Blue Marble" composite cloud-free earth ssurface image, today's images from NASA TERRA and AQUA satellites (from JPL), shaded topography images of many resolutions, named thermal feature locations, and much more.

Hold the mouse pointer over any catalog item to see a very complete description about the data, in most cases.

You can adjust transparency of any image display with the display control's "Transparency" slider.

One advantage of using data from a WMS is that the data resolution increases as you zoom in.

If the catalog display list gets confused, reenter the catalog's URL.

The sample image to the left (click for full size) has a shaded and colored topography image plus a rivers image.
