Visibility on Terrains
arXiv:2610.00796
Abstract
This chapter surveys terrain visibility models, algorithms, and applications. It introduces basic definitions, from line-of-sight, single-viewpoint viewsheds to cumulative and total viewsheds, on both Triangulated Irregular Network (TIN) and regular grid terrains. Reviews exact and approximate algorithms and highlights key application domains including archaeology, visual exposure to greenery, scenic route management, and land conservation.
