01.11.2011 - Topography of Vesta’s equatorial region I

These Dawn FC (framing camera) images show part of Vesta’s equatorial region, which contains impact craters and troughs (linear depressions). The left image is an albedo image, which is taken directly through the clear filter of the FC. Such an image shows the albedo (eg. brightness/ darkness) of the surface. The right image uses the same albedo image as its base but then a color-coded height representation of the topography is overlain onto it. The various colors correspond to the height of the area that they color. For example, the white in the bottom right of the right image is the highest area and the blue areas in the central crater and the top of the right image are the lowest. Below the central crater there is a long low area running obliquely across the image (blue and green colors), which is not as clear in the left albedo image. The topography is calculated from a set of images that were observed from different viewing directions, these are called stereo images.
