Fast approximation of visibility dominance using topographic features as targets and the associated uncertainty [PDF]

open access: yes, 2003
An approach to reduce visibility index computation time andmeasure the associated uncertainty in terrain visibility analysesis presented. It is demonstrated that the visibility indexcomputation time in mountainous terrain can be reduced substantially ...
