Description: This Lunar Orbiter global digital mosaic was constructed using data aquired by LO III, IV and V; High- and Medium- Resolution cameras that were projected to Equirectangular projection at 512 pixels/degree (~59.0 meters/pixel). A high pass boxfilter was applied to the individual frames before mosaicking in order to normalize the relative brightness. The results emphasize the high-frequency data by retaining only 10% of the low-frequency brightness variation. For further information, contact Tammy Becker (tbecker at usgs.gov)

These tiles are stored in a GIS-ready, 8bit GeoTiff with an embedded Lunar definition of 1737400.0 m radius in a geographic coordinate system at 0.0019 degrees/pixel (512 p/d or ~59m/p). The longitudes are in a -180 to 180 system to keep the near-side centered, although the quads are labeled with using 0 to 360 longitudes. Polar areas are available in geographic (lat/lon) and Polar Stereographic projection.
