The visual impact of crop shelters in the rural landscape is paramount importance for sustainability planning. It utmost to protect a beautiful characterized by archaeological sites and natural ecosystems but it also fundamental preserve key economy based on agriculture. To there need understand its units assess feasibility application character assessment (LCA) at local scale adaptation higher...

This paper describes a new parallel raster terrain visibility (or viewshed) algorithm, based on the sweep-line model of [Van Kreveld 1996]. Computing the terrain visible from a given observer is required for many GIS applications, with applications ranging from radio tower siting to aesthetics. Processing the newly available higher resolution terrain data requires faster architectures and algor...

In coastal communities with uniform flood risk, amenity value is comprised of two components – view and access. Having controlled for view, it is assumed that any residual amenity value represents the benefit derived from households from accessing the beach for leisure or recreational purposes. However, as properties closer to the beach typically have improved viewsheds, the two amenities are h...

This paper describes a means for linking Ž eld and object representations of geographical space. The approach is based on a series of mappings, where locations in a continuous Ž eld are mapped to discrete objects. An object in this context is a modeler’s conceptualization, as in a viewshed, highway corridor or biological reserve. An object can be represented as a point, line, polygon, network, ...

A suite of recently developed statistical methods to estimate the abundance and density unmarked animals from camera traps require accurate estimates area sampled by each camera. Although viewshed is fundamental achieving estimates, there are no established guidelines for collecting this information in field. Furthermore, while complexities detection process motion sensor photography generally ...

In this study, we developed a 3D-model-based technology that can evaluate solar access by analyzing radiation and shade to find the optimal location for system. We an algorithm quickly calculate viewshed applying ray-casting technology, which is useful in field of computer graphics. To apply unmanned aerial vehicle (DJI MAVIC 3) was used create 3D model taking 320 photos Kangwon National Univer...
