Abstract
Two research projects are in progress at the University of Western Ontario in the area of lunar and planetary cartography. The first addresses a problem unique to space exploration, the mapping of bodies with extremely irregular shapes. Shapes are determined by modifying a triaxial ellipsoid until its limb and terminator reproduce those seen in all available images, given appropriate orientation and lighting. Morphographic map projections are used for maps of such bodies. The second project involves documenting the history of lunar and planetary cartography, supported by bibliographic research and collection of contemporary maps. Part of this work involves identifying very old lunar maps. Possible examples include rock carvings 4500 years old from Knowth, Ireland and sections of medieval mappaemundi.
