This CD is part of a 22 volume set that contains the 750-nm "Clementine HiRes Mosaic" of Earth's Moon covering sub-polar latitudes from 80 deg S to 80 deg N, and the poles above 80 deg. The HiRes mosaics use images from the Clementine HiRes camera taken with the 750 nm ("D") filter. The sub-polar mosaics are mapped in the sinusoidal equal-area projection at a resolution of 20 meters per pixel, while the HiRes polar mosaics employ the stereographic projection at a scale of about 30 meters per pixel at the pole.
The polar mosaics cover latitudes above 80 degrees. The mosaics are divided into square tiles 2250 pixels (approximately 2.2 deg) on a side, which nominally covers the polar region with 100 tiles. Two mosaics were generated for each pole: one using data from the north periapsis phase of the mission, the other using data from the south periapsis phase. This yields mosaics of generally uniform resolution, exposure, gain and offset. The following table summarizes the polar coverage
The HiRes polar mosaics are geometrically and photometrically tied to the UV/Vis Basemap Mosaic, which is a radiometrically and geometrically controlled, photometrically modeled global image mosaic compiled using images from the 750 nanometer filter observations of the Clementine Ultraviolet / Visible camera. The basemap mosaic is mapped in the orthographic projection at a resolution of 150 meters per pixel.
A detailed description of the Clementine HiRes Mosaic with information about the organization and compilation of the database is provided in the file volinfo.htm . Please refer to this document for more information.
The image files are organized according to NASA's PDS standards. An image file (tile) comprises a PDS labeled file containing an "image object". Software tools such as ISIS enable users to manipulate the images. ISIS may be obtained from the USGS Astrogeology Team.
