The Chandra Source Catalog (CSC) contains multi-resolution, exposure corrected, background subtracted, full-field images that are stored as individual FITS files and as three-color JPEG files. In this poster we discuss how we took these data and were able to, with relatively minimal effort, convert them for use with the Google Earth (GE) application in its Sky mode. We will highlight some of the challenges which include converting the data to the required Mercator projection, reworking the 3-color algorithm for pipeline processing, and ways to reduce the data volume through re-binning, using color-maps, and special Keyhole Markup Language (KML) tags to only load images on-demand. The result is a collection of some 11,000 3-color images that are available for all the individual observations in the CSC Release 1. We also have made available all ~4000 Field-of-View outlines (with per-chip regions), which are trivial to produce starting with a simple dmlist command.
