DETERMINATION OF LANDMARK TOPOGRAPHY FROM IMAGING DATA

摘要

Viking, MOC and MOLA data are being used to construst high resolution topographic and albedo models of landmarks on Mars. These models can be reilluminated and correlated with in-flight images, acting as body-fixed navigation tie-points. A similar procedure, using sparse stereo points in place of MOLA data, is being used to map small bodies such as Phobos and Deimos.
