CLEMENTINE UVVIS DIGITAL IMAGE MODEL

Clementine UVVIS Digital Image Model

Information and Browser for CD Volume CL_4044

This CD is one of 78 CD volumes that contain the full resolution Clementine UVVIS Digital Image Model (DIM) of Earth's Moon. This multispectral lunar DIM is a radiometrically and geometrically controlled, photometrically modeled global image mosaic compiled using more than 400,000 images from multiple filter observations of the Ultraviolet/Visible (UVVIS) camera onboard the Clementine Spacecraft. The DIM mosaic is mapped in the Sinusoidal Equal-Area projection at a resolution of 100 meters per pixel requiring approximately 68 gigabytes of digital storage. This database is partitioned into quads or "tiles" equivalent to the previously released Clementine 750-nanometer Basemap Mosaic (PDS volumes CL_3001 through CL_3015). Tiles are stored as image files of approximately 2100 pixels on a side. Pixels are 16-bit signed integers. A phase angle image database, at equivalent resolution, accompanies the UVVIS DIM. Additional CD volumes will contain supplemental ancillary information and reduced-resolution planetwide coverage at 0.5, 2.5, and 12.5 km/pixels. The full-resolution tiling and CD volume archive scheme is available here (Adobe PDF Format). A volume-quad locator map is also available (locator requires JavaScript enabled browser).

A detailed description of the Clementine UVVIS DIM 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 Clementine UVVIS Mosaic was compiled for the National Aeronautics and Space Administration (NASA) by the United States Geological Survey (USGS) under the direction of Eric M. Eliason (USGS) and Alfred McEwen (University of Arizona). Mark Robinson (Northwestern University) provided tremendous support and expertise in the compilation of the UVVIS DIM mosaic. Ella Lee and Tammy Becker headed the USGS technical group responsible for its compilation. Cartographic and archive design, data conversion for PDS compliance, and production of the CDs were performed by Chris Isbell. The Lunar Geometric Control network was derived by Mert Davies and Tim Colvin (both from the RAND Corporation). Generation of the UVVIS DIM is a very complex process that involves and depends on an extended number of people. See the acknowledgements section of the document/volinfo files for a complete list of those who contributed.

The Clementine UVVIS DIM can be obtained by contacting the Planetary Data System (PDS) Imaging Node. For more information contact Eric Eliason, U.S. Geological Survey, 2255 North Gemini Drive, Flagstaff, AZ 86001 [telephone: (520) 556-7113, e-mail: eeliason@usgs.gov].

The image files are organized according to NASA's PDS standards. An image file (tile) is organized as a PDS labeled file containing an "image object". Additionally, each image file is associated with an Integrated Software for Imagers and Spectrometers (ISIS) "qube object" detached label. This detached label allows for images to be accessed and processed in the ISIS system (available through the USGS, Flagstaff, AZ). Within ISIS, users should reference the detached label file when accessing image files on this CD set. Other access tools are available that support the Clementine UVVIS DIM. A software tool called "MapMaker" enables users to extract seamless mosaics of images for any latitude-longitude region and at a variety of scales in different map projections. MapMaker, available for distribution through the PDS Imaging Node, can output images in a variety of formats common to the user community (gif, jpeg, tiff, PDS). Also, see the "NASAView" discussion below in the "Image Display for Full Resolution Image Products" section.

Digital storage requirements for the full resolution image products range from ~35MB to ~55MB. These images have the 'img' filename extension and are found in the 'data' directory.

Image Display for Full Resolution Image Products

In addition to displaying reduced resolution 'browse' images, the graphics based interfaces provided above are also designed to allow for display of full resolution image products through the use of 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. The current version (V2.5.2 as of release date of this CD) of NASAView supports only single band PDS images. The UVVIS DIM products are multi-band image cubes and currently cannot be accessed within NASAView. A new version of NASAView that will support multispectral data is planned for release in late summer 1999. See the PDS Home Page for more information on NASAView and it's availability (http://pds.jpl.nasa.gov/). The PDS Home Page will lead you to the site for direct access to NASAView which is (as of release date of this CD) http://pds.jpl.nasa.gov/license.html. Once the proper version of NASAView is installed on your system, it can also be incorporated with your web browser as a helper application. Refer to your particular web browser documentation for information on helper applications.
