OnEarth KML layers The Tiled WMS is used to provide data using the KML 2.1 onRegion update.

http://OnEarth.jpl.nasa.gov/OnEarth_GlobalMosaic.kml is the tiled version of the global 15m Landsat 7 derived WMS Global Mosaic. This is the pseudocolor style, pansharpened, using both infrared and visual bands.

http://OnEarth.jpl.nasa.gov/OnEarth_GM_Visual.kml is the tiled version of the global 15m Landsat 7 derived WMS Global Mosaic, visual. This is the visual style, which uses color derived from the red green and blue spectral and brightness from the panchromatic band.
