Visibility analysis of landmark-based navigation
… the chromatic art gallery problem in which the visibility graph of the landmarks is required to be connected. The chromatic art gallery problem can be phrased in terms of a landmark placement problem combined with a graph coloring problem. The landmarks are placed such that each point in the …

Automatic tool path generation for multi-axis machining
… CAD/ CAM system. We perform the accessibility analysis in two stages. First, we triangulate the surface of the workpiece and perform a visibility analysis from a discrete set of orientations arranged on the Gaussian Sphere. This analysis is performed in object space to ensure reliability. For …

Fantastic hillforts and where to find them: a region-based landscape analysis of the Iron Age in Britain and the methods we use to assess the past
… research schools, and more importantly my own analysis, have been combined and presented in synthesis, to emphasise the connectivity between these two methods, much like the regional connectivity being investigated. I performed visibility analysis on the two regions– one of the most popular …

GPS augmentation using digital spatial data
… modelling and prediction of GPS satellite visibility using DSMs; and prediction of GPS multipath effect using DSMs and building footprints. These experiments are closely related to each other in the sense that GPS and spatial data are combined to provide value-added information for improved …

Adaptive Processing of Laser Scanning Data and Texturing of the Segmentation Outcome
… procedure is implemented while investigating the visibility of the laser scanning-derived surfaces in the existing images using a newly-developed visibility analysis/occlusion detection technique. The feasibility of the proposed processing and texturing approaches is verified using simulated and …

Visibility computation through image generalization
… the image generalization paradigm for computing visibility. The paradigm is based on the observation that an image is a powerful tool for computing visibility. An image can be rendered efficiently with the support of graphics hardware and each of the millions of pixels in the image reports a …

Visible Dead: Ancestral Landscapes in Prehistory between the Mediterranean and the Near East
… a semantic approach to movement, and a cache of visibility analyses within a 3D GIS to verify the visual impact of the selected necropolises from reconstructed optimal path networks.

Castles and Communities: Using the taskscape to explore the attitudes, activities, and lived experience of wider communities in castle landscapes between 1050 - 1550.
… the landscape is modelled using a retrogressive analysis of historic maps and LiDAR imagery. Portable Antiquity Scheme data, excavations, and historical and archaeologically attested sites and places are then integrated into a model of the physical and social topography of the medieval world. …
