THEMIS infrared geodetically controlled mosaics, updated spacecraft pointing and orientation information (i.e., preliminary smithed SPICE kernels), and supporting documentation are available for download and public use from the United States Geological Survey (USGS) Astrogeology Science Center.  Nine daytime infrared and eight nighttime infrared mosaics are currently available, with additional mosaics being released each January and July until a global product is completed.  These mosaics are tied to a known coordinate system (USGS Viking Orbiter Mars Digital Image Model 2.1), and images are spatially adjusted to align feature boundaries and orthoprojected at 100 m/pixel scale.  This process results in sub-pixel registration between images and the daytime IR and nighttime IR mosaics to be well-registered to one another. These products enhance our knowledge (e.g., position, precision, and accuracy) of image placement and the location of small-scale surface features, and will benefit the current and future orbital acquisition of data, the planning of spacecraft and surface operations, and allows for easier and improved intercomparison of all Mars data sets.
