ISPRS 1999 Revision of the Mars Control Net and Global Digital Image Mosaic
In the late 1980s, the USGS, Flagstaff, produced the first in what would become a series of very large, global digital image mosaics of solar system bodies. This Mars mosaicked digital image model (MDIM) incorporated roughly 4600 Viking Orbiter images. The global mosaic, at a scale of 1/256 degree or ~231 m/pixel, was widely distributed on 6 CD-ROMs produced in 1991. As the highest resolution global map of Mars, the MDIM is vital for both scientific studies and planning of current and future missions. Unfortunately, it has significant shortcomings, particularly in the accuracy of geodetic control (i.e., the accuracy of feature positions). Geodetic accuracy is a particular concern for mission planning, which involves targeting of observations and navigation of landers to specific ground points.
