Best of Two Worlds: Combining High and Low Resolution to Compute Viewsheds on terrains
Laura Toma
The viewshed of a point on a grid terrain , viewshed, is defined as the set of grid points in that are visible from . We describe a novel algorithm for computi…

A Comparison of I/O-Efficient Algorithms for Visibility Computation on Massive Grid Terrains
Herman Haverkort, Laura Toma
Given a grid terrain T and a viewpoint v, the viewshed of v is the set of grid points of T that are visible from v. To decide whether a point p is visible one needs to interpolate…
