I discovered  geomorphological mapping quite recently to be honest.

Geomorphology is part of the broad range of disciplines that fall under the general heading of earth sciences,

including geology & geography. 

But here, it's not about landform mapping but more emotional mapping based on environmental unconscious perceptions.

I image a full geometric description of  imaginary landforms.

Each black mark is organized into hierarchically arranged classes with spatially & emotionally variable properties
and geometric relationships.
