| Data Set Abstract |
This CD contains portions of the Clementine HiRes Lunar Mosaic, a
geometrically controlled, calibrated mosaic compiled from
non-uniformity corrected, 750 nanometer ('D') filter
high resolution observations from the HiRes imaging system
onboard the Clementine Spacecraft. 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. |
