Filled and empty lakes on Titan
These images provide a view of filled and empty lakes on Saturn's moon Titan as observed by the international Cassini mission.
The top (A) panel shows a Cassini RADAR image obtained using the instrument's Synthetic Aperture Radar (SAR) Imager. In the second panel from top (B) a digital terrain model is shown with black contour line and a colour scale indicating altitude on top of the RADAR SAR image (shown in grey scale); filled lakes are indicated with blue contour lines and empty lakes with yellow lines. The third panel from top (C) shows the emissivity measured by Cassini, along with contours from the digital terrain model and indications of filled and empty lakes.
The filled lakes in panel B enclosed in the white solid frame are shown in greater detail in panels D and E in the bottom left part of the image, where rampart features are shown in red. The empty lakes in panel B enclosed in the white dashed frame are shown in greater detail in panel F in the bottom right part of the image.
