CLEMENTINE HIRES MOSAIC

These mosaics cover sub-polar regions between 80 deg S and 80 deg N with the sinusoidal equal area mapping at 20 m/pixel, and the polar regions above 80 deg with a stereographic mapping at 30 m/pixel resolution at the poles.

The geometric control is provided by the 100 m/pixel USGS Clementine Basemap Mosaic (PDS CD-ROM Volumes CL_3001-3015) compiled from the 750 nm Ultraviolet/Visible Clementine imaging system and, for the polar mosaics, from the 150 m/pixel polar basemap mosaic. Calibration was achieved by removing image nonuniformity largely due to the HiRes system's light intensifier. Also provided are offset and scale factors which transform the 8-bit HiRes data to approximate photometric units, achieved by a fit of the HiRes data to the corresponding UV/Vis basemap, which is photometrically calibrated.
