False-colour oblique view of Lakshmi Planum, part of the Ishtar Terra 'continent' of Venus. This view is from a point 25 degrees above the horizon and is looking north. The image was made by combining a shaded relief map based on Venera 15/16 and Pioneer Venus (spacecrafts) altimetry with a colour-coded radar brightness image made by the Arecibo Observatory. The large, purple area is Lakshmi Planum which has two major volcanic calderas; Sacawajea (right) and Colette (left). Along the top of the plain is the line of the Akna Montes (orange), with the massive Maxwell Montes (also orange) at far right. The vertical scale of this view has been exaggerated by a factor of 50.
