A rapid and flexible parallel approach for viewshed computation on large digital elevation
models is presented. Our work is focused on the implementation of a derivate of the R2 …

Microwave backhaul links are often used as wireless connections between
telecommunication towers, in places where deploying optical fibers is impossible or too …

Viewshed analysis is of great interest to location optimization, environmental planning,
ecology and tourism. There have been plenty of viewshed analysis methods which are …

We present a parallel GPU algorithm for computing viewshed using the radial-sweep
approach, and we are considering the case of in-memory execution. We compared our …

This article presents TiledVS, a fast external algorithm and implementation for computing
viewsheds. TiledVS is intended for terrains that are too large for internal memory, even more …

Existing intervisibility analysis methods suffer from computational inefficiency due to
redundant sampling points. To address this issue, we propose a new approximate method …

Let T be a terrain, and let P be a set of points (locations) on its surface. An important problem
in Geographic Information Science (GIS) is computing the visibility index of a point p on P …

Given a terrain T and a point v, the viewshed or visibility map of v is the set of points in T that
are visible from v. To decide whether a point p is visible one needs to interpolate the …

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 the …
