23.02.2012 - Apparent brightness and topography images of Cornelia crater

The left-hand image is a Dawn FC (framing camera) image, which shows the apparent brightness of Vesta’s surface. The right-hand image is based on this apparent brightness image, which has had a color-coded height representation of the topography overlain onto it. The topography is calculated from a set of images that were observed from different viewing directions, which allows stereo reconstruction. The various colors correspond to the height of the area. The white and red areas in the topography image are the highest areas and the blue areas are the lowest areas. It is clear from both of the images that the two craters are depressions, which have lower elevations than the surrounding areas. But, the topography image shows that the left side of the image has a higher elevation than the right side, something that is not clear in the apparent brightness image.
