The SAR images are black and white images, which show the surface features using the intensity of radar return (echo), either due to surface roughness or orientation. [7] For SAR imaging, spacecraft do not point directly downward (nadir) but slightly to the side—anywhere from about 10° to 45°.
The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the surface lies within an elevation of -1.0 and 2.5 km) [1] that preserves geologic structures for long periods of time.

Water on Venus is the hypothesis that for 2 billion years, a shallow liquid water ocean may have covered the surface of Venus. [1] It is thought that dry land lying near the equator would have limited the evaporation of oceans and the greenhouse effect , allowing liquid water on Venus.

The surface of Venus is comparatively flat. When 93% of the topography was mapped by Pioneer Venus Orbiter, scientists found that the total distance from the lowest point to the highest point on the entire surface was about 13 kilometres (8.1 mi), about the same as the vertical distance between the Earth's ocean floor and the higher summits of the Himalayas.
These three features are now the only ones on Venus that do not have female names. [48] First view and first clear 180-degree panorama of Venus's surface as well as any other planet than Earth (1975, Soviet Venera 9 lander). Black-and-white image of barren, black, slate-like rocks against a flat sky. The ground and the probe are the focus.
