Abstract

During its year-long orbital survey of Asteroid 433 Eros (February 14, 2000 to February 12, 2001) the NEAR Shoemaker spacecraft returned over 160,000 images of the surface, obtained under a wide variety of viewing conditions and resolutions. To handle this large volume of images of Eros, we have utilized specialized techniques for projecting, mosaicking, and photometrically analyzing images of irregular objects. Local incidence and emission angles are calculated on a pixel-by-pixel basis from the global shape model to produce a normalized reflectance map of the entire asteroid. This map provides not only a medium resolution (∼ 10 m/pixel) scientific product in its own right but also a regional context for high-resolution (< 1 m/pixel) image sequences.
