CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Map of Titan - April 2011

This global digital map of Saturn's moon Titan was created using images taken by the Cassini spacecraft's imaging science subsystem (ISS).

The images were taken using a filter centered at 938 nanometers, allowing researchers to examine variations in albedo (or inherent brightness) variations across the surface of Titan. Because of the scattering of light by Titan's dense atmosphere, no topographic shading is visible in these images.

The map is an equidistant projection and has a scale of 2.5 miles (4 kilometers) per pixel. Actual resolution varies greatly across the map, with the best coverage (close to the map scale) along the equator near the center of the map at 180 degrees west longitude and near the left and right edges at 0 and 360 degrees west longitude. The worst coverage is on the leading hemisphere (particularly around 120 degrees west longitude) and in some northern latitudes. Coverage in the northern polar region continues to improve as the north pole comes out of shadow after Titan's northern vernal equinox in August 2009. Large dark areas, now known to be liquid-hydrocarbon-filled lakes, have been documented at high latitudes (see PIA11146).

This map is an update to the version released in February 2009 (see PIA11149). Data from the last two years, including the most recent data in the map from April 2011, have improved coverage in the southern trailing hemisphere and over portions of the north polar region.

The mean radius of Titan used for projection of this map is 1,600 miles (2,575 kilometers). Titan is assumed to be spherical until a control network -- or model of the moon's shape based on multiple images tied together at defined points on the surface -- is created at some point in the future.

The Cassini Solstice Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.

Hello Weasel.
If I recall, that round structure is believed to be an impact crater. the only visible evidence of impact on Titan, so far. if i am not mistaken, clouds do not show up at the wave lengths where these images are taken.
you are dead right about this being a wonderful mosaic.

Is the ringed spot at about 25/85 a large storm cloud? Wonderful mosaic of an immensely interesting and unique satellite.
