Abstract

In 2001, geophysicist Dave McAdoo, viewing CSNB folded forms resembling Brazil nuts, observed that if a planet had been that shape, then the source map (Fig. 1.10c) would be an excellent 3D model for that planet. This led to CSNB mapping of asteroids (Clark 2002, 2003). When highly segmented CSNB maps of asteroids are folded, they produce reasonable, if not excellent, 3D representations; thus, CSNB mapping becomes a powerful 3D modeling, visualization and educational tool. We have used the CSNB approach to map and model asteroids to provide far more morphological insight than can be gained in the context of traditional flat (2D) map projections and regular plate (3D) models (Clark and Clark 2005, 2006a).
