Here is a mosaic of Xanadu that includes:
  • Section of Oct 2007 Titan Map (PIA08399)
  • T47 SE Xanadu - Hotei Arcus mosaic
  • T13 SAR RADAR Swath (PIA08552)
  • T3 SAR RADAR Swath (left part from VP's website)
  • T20 SAR distant targeted look (also from VP's website)
  • PIA10654 SAR image of tectonic ridges in NW Xanadu

Attached Image

Some of the higher latitude swaths were skewed slightly by myself to try to better fit the ISS projection. There are mismatches, particularly for the non-equatorial swaths. The resolution is approximately 6 km/pixel.

A higher resolution (ca. 1.4 km/pixel) jpeg can be downloaded here (WARNING: 7 Mb file)

This will be a handy basemap for Xanadu mosaics and the upcoming RADAR releases.

Mike -- can you post a version of the VIMS/radar blink comparison with the VIMS image fully opaque? I've found that when you do a blink comparison with one image translucently overlaid over the other, the translucency makes it hard to determine which things really are a synchronicity between the images.

Anyway, awesome work. Thanks!

Sure. Here it is (I toned down the saturation to a more reasonable level for a fully opaque image):

(click to animate)

Warning: The eye tries to make a "jump" between the RADAR-dark area and the VIMS blue area. But it is the RADAR-bright areas S of the RADAR-dark areas that line up with the VIMS blue areas. (so...Titan's Blue Ridge mountains?) This is why I prefer the translucent image above. Use the mouse cursor to serve as a placemarker on the blinked images.

(In fact, when I first read these articles a while ago, my eyes were guilty of making the same jump: doing the overlay exercise really helped me understand the text.)
