Clouds of Neptune
This Voyager 2 high resolution color image provides obvious evidence of vertical relief in Neptune's bright cloud streaks. These clouds were observed at a latitude of 29 degrees north near Neptune's east terminator, the "line" on a planet where daylight meets darkness.
The resolution of this image is 6.8 miles per pixel. The width of the cloud streaks range from 31 to 124 miles, and their shadow widths range from 18 to 31 miles. Cloud heights appear to be around 31 miles.
