InSAR images can be displayed in mapped views. Since there is no standard for InSAR interferogram image formats, they are treated like other images in the IDV for Earth-location.

The advantage of InSAR displays in the IDV is that you can include most any other geophysics data in the same display, and use the interactive 3D controls to find and show relations betweem the InSAR and other phenomena. You can also drape the imagery over 3D topograhic relief (high quality topography data is easily available with the IDV ; see Topography Data Sources for the IDV ).

The interferogram image shown here is provided to UNAVCO by John Bell, University of Nevada, Reno.
