Clementine Basemap Mosaic (version 2)


Description: These Clementine tiles represent the version 2 basemap mosaic (750nm with fill from other bands). This version supercedes the original "warp" basemap. More from the readme.

These are stored in a GIS-ready, 8bit GeoTiff with an embedded Lunar definition of 1737400.0 m radius in a geographic coordinate system at 0.0033 degrees/pixel (~303 p/d or 100m/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. The method used to convert from a 32bit to a 8bit image was to linearly stretch the data range from (0.048, 0.5) down to (1, 255) leaving 0 for NODATA. This resulted in some value saturation especially at the poles. Polar areas are available in geographic (lat/lon) and Polar Stereographic projection. Updated Apr, 2009.

Note: The other 16bit warped bases are still valid for spectral use (e.g. minreral maps).
