GIS-based visibility analysis

M Gillings, D Wheatley - Archaeological Spatial Analysis, 2020 - taylorfrancis.com
In this chapter we examine critically the role of GIS in the study of vision and visibility. We
begin with a brief outline of the ways in which visual characteristics have been integrated …

On the complexity of minimum-link path problems

I Kostitsyna, M Löffler, V Polishchuk, F Staals - arXiv preprint arXiv …, 2016 - arxiv.org
We revisit the minimum-link path problem: Given a polyhedral domain and two points in it,
connect the points by a polygonal path with minimum number of edges. We consider …

Practical approaches to partially guarding a polyhedral terrain

F Kammer, M Löffler, P Mutser, F Staals - Geographic Information Science …, 2014 - Springer
We study the problem of placing guard towers on a terrain such that the terrain can be seen
from at least one tower. This problem is important in many applications, and has an …

A faster algorithm to compute the visibility map of a 1.5 D terrain

M Löffler, M Saumell, RI Silveira - Abstracts 30th European …, 2014 - upcommons.upc.edu
Given a 1.5 D terrain, ie, an x-monotone polygonal line in R 2 with n vertices, and 1 mn
viewpoints placed on some of the terrain vertices, we study the problem of computing the …

Distributed multi-agent deployment for full visibility of 1.5 d and 2.5 d polyhedral terrains

A Ma, J Cortés - Journal of Intelligent & Robotic Systems, 2020 - Springer
This paper presents deployment strategies to achieve full visibility of 1.5 D and 2.5 D
polyhedral environments for a team of mobile robots. Agents may only communicate if they …

Visibility-based distributed deployment of robotic teams in polyhedral terrains

[PDF][PDF] Geometric Algorithms for Trajectory Analysis

F Staals - 2015 - fstaals.net
Movement is a phenomenon that we encounter every day. Almost everyone and everything
in our world moves: we walk to go shopping, we cycle to work, we drive to the gym, and we …

Realistic terrain features and the complexity of joint viewsheds

GT Meijer - 2020 - studenttheses.uu.nl
Computing viewsheds from different viewpoints is an important procedure with many
applications in multiple Geographic Information Science (GIS) fields. While much research …
