The Imaging Node maintains and distributes the archives of
planetary image data acquired from NASA's flight projects with the
primary goal of enabling the science community to perform image
processing and analysis on the data. The Node provides direct and
easy access to the digital image archives through wide distribution of
the data on physical media (CD- and DVD-ROM) and through on-line
remote-access tools by way of Internet services. The Node provides
digital image processing tools and the expertise and guidance
necessary to understand the image collections.
The data collections, now approaching five terabytes in volume,
provide a foundation for remote sensing studies for virtually all the
planetary systems in our solar system (except for Pluto). The Node is
responsible for restoring data sets from past missions in danger of
being lost. The Node works with active flight projects to assist in
the creation of their archive products and to ensure that their
products and data catalogs become an integral part of the Node's data
collections.
On-Line Capabilities:
Many of the image data sets available through the Node reside on
CD-ROM data volumes and are accessible via World Wide Web services (with
few exceptions as indicated below under Data Holdings). The web
services allow users to browse the image collections, order data
products, extract documentation and ancillary data, and obtain
processing software. The user resource link for the Imaging Node page
is shown below.

NASA Planetary Photojournal
The Photojournal, developed in collaboration with the Solar System
Visualization Project and JPL's Media Relations Office (formerly the
Public Information Office), enables easy access to NASA's archive of
publicly released planetary images for viewing and use by the public,
scientists, educators and publishers. The site features thumbnail and
browse-size versions of the images for viewing, captions and ancillary
information, direct digital downloading in a variety of formats and sizes,
and links to vendors for ordering photographs, slides and CD-ROMs.
The Photojournal can be accessed at the following URL.

Planetary Image Navigators
The Node is working in a collaborative effort with the Geosciences and
Engineering Nodes and the Interactive Planetary Atlas project to establish
a Web service for search and retrieval of the image data collections.
Images can be selected based on geographic location, the camera
operating modes, viewing conditions, and other observational
parameters, utilizing either a map-based or forms-based interface.
Resulting images can be displayed, downloaded directly, or ordered to
be delivered by ftp (file transfer protocol) or on CD-ROM media. The
image navigators for the Clementine and Viking Orbiter missions are
operational and can be reached through the Imaging Node Home Page.
