This example shows the sensitivity of the length of the shadow of a hill as a function of the distance from the terminator.

It's also an example of a long-baseline observation, which is useful to dermine the height of a mountain by measurements of the observed parallax.

These crops of equirectangular maps derived from PJ57 image JNCE_2023364_57C00025_V01 and PJ58 image JNCE_2024034_58C00029_V01 have a resolution of 30 pixes per degree, and are displayed with north to the right.
