Access to Mars Global Surveyor data through the Planetary Image Atlas.

The Planetary Image Atlas was developed by the Imaging Node of the Planetary Data System (PDS) at JPL and the USGS in Flagstaff with support from the Solar System Visualization (SSV) task and the Multimission Image Processing Laboratory (MIPL) at JPL. The Atlas is designed to be a single interface, through which a user can search for, display, and download images and other ancillary data for many planetary missions. It will eventually replace existing Imaging Node image browsers and catalog search engines. Currently, the Atlas supports Galileo, Mars Pathfinder and Mars Global Surveyor. Older Imaging Node browsers, which provide access to data from the Clementine, Magellan, Viking Lander, and Viking Orbiter missions, are now being incorporated into the Atlas. Mariner 9 data are also being added to the system, along with several new features which will be available by the end of the year 2001. New Mars Global Surveyor datasets are being introduced to the Atlas in 2001 and 2002 as they are being released to the PDS. They include Mars Orbiter Camera (MOC) images, Mars Orbiter Laser Altimeter (MOLA) topography and a subset of the Thermal Emission Spectrometer (TES) data (Lambert albedo). We plan to add other products such as the MOLA gridded datasets and pulse widths, and the TES thermal inertia and dust opacity data, as they become available through the PDS. We plan to enable new search capabilities in the Atlas, including searches of MOLA and TES data based inside latitude-longitude boundaries and/or time domain (i.e., data corresponding to a MOC image or a particular event such as a dust storm). Users will receive output in text format. Some plotting capabilities will also be available. Currently, searches for MOLA topography data corresponding to a particular MOC images are operational. The databases are updated as soon as new data is released to the PDS from the instrument teams. In the long run, the Atlas will be able to output data in formats compatible with some of the Geographic Information Systems (GIS), such as ArcView. This resource can be used extensively by anyone interested in Mars data research and analysis. >http://www-pdsimage.jpl.nasa.gov/PDS/public/Atlas</a>
