Clementine HiRes 750-nm Mosaics

Information and Browser for CD Volume CL_6018

This CD is part of a 20 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 sub-polar mosaics are organized into twelve 30-deg wide longitude zones and two latitude zones of 80 deg extent, which defines 24 grids. This organization mirrors that of the Clementine UV/Vis basemap (CD-ROM volumes CL_3001-3015, available from the PDS), which provides the geometric control for the HiRes mosaics. Generally, the data products from a single grid fill a single CD, although where feasible the two latitude zones were combined into a single CD. The table shown below summarizes the contents of each CD volume.

The mosaics of each grid are tiled into convenient strips of approximately 1.75 deg latitude extent (2653 lines) and widths correponding to the tile's valid data extent, usually no more than about 300 pixels.

The HiRes 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 Sinusoidal Equal-Area projection at a resolution of 100 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.

You can view browse versions (reduced resolution images) of the mosaic tiles on this CD with UV/Vis basemap context with a graphics-based interface.

Image Display for Full Resolution Image Products

In addition to displaying reduced resolution 'browse' images, the text based interface also permits display of full resolution image products using a web-browser helper application. The program NASAView can be used for this purpose. NASAView is a PDS product display tool that runs on multiple platforms with a common graphical user interface. See the PDS Home Page for more information on NASAView and it's availability ( Once NASAView is installed on your system, it can be incorporated with your web browser as a helper application. Refer to your particular web browser documentation for information on helper applications.
