Gravity map

[1] Other methods include analysis of artificial satellite orbital mechanics, which can allow comprehensive gravity maps of planets, as has been done for Mars by NASA.

[1] Gravity maps, in a 'heat' context, typically represent intensity being representative of concentrations of mass in a given area, which correlates to that area having a stronger gravitational field; an example would be a mountain range.

[3] In the inverse, geological structures such as oceanic trenches or landmass depressions such as those caused by glaciers or fault lines will depict lower gravitational field values, due to the lower underlying amount of mass in the area.
