A comparison of the MOLA topographic profile data with existing digital
topography indicates the presence of both systematic and significant local
and regional differences. These differences are in part related to the
coordinate system and parameters defining these datasets but also to the
data originally used in the development of the models. The relationship
of the MOLA topography to the 6.1 mbar atmospheric pressure surface, the
USGS maps, and Viking image datsets will be discussed.
