This global digital map of Enceladus was created using data taken by the Cassini spacecraft, with gaps in coverage filled in by Voyager spacecraft data. The map is an equidistant projection and has a scale of 300 meters (980 feet) per pixel.
The mean radius of Enceladus used for projection of this map is 252 kilometers (157 miles).
This map is an update to the version released in December 2005. See PIA07777.
***ERRATA (2008-02-13): Longitude System Discrepancy***
The IAU (International Astronomical Union) cartography working group recommended to use the longitude system as defined by Davies and Katayama (1983). This recommendation is described in Seidelmann et al., 2007 and means that crater Salih should have a fixed longitude of 5 degrees West.
The ISS team was not aware of this recommendation during the preparation of the Enceladus atlas and noted now that there is a slight difference (about 0.9 degrees) between the longitudes given in this atlas and the IAU definition. Crater Salih is hardly visible in the Cassini images and it is therefore difficult to estimate the exact difference.
Fortunately, crater Salih will be imaged with better resolution during the upcoming Enceladus flybys in 2008. The ISS team will use these coming images to determine the exact shift between the current atlas and the IAU definition and will release a corrected (shifted) version of this atlas in 2009.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. 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.
