The smallest scale topographic map of the Iani Chaos region on Mars. The scale is just 1:50 000. The contour lines are now only 50 meters apart. At these smaller scales, more textural details of the surface can be recognised. Credit: Map Compilation: Technische Universitä´ Berlin, 2006; Image Data: ESA / DLR / FU Berlin (G. Neukum)
