A visual analysis is useful to assess potential impacts our surroundings. There has been tremendous progress toward the optimization, accuracy, and techniques of these analyses. Viewshed analyses are a common type analysis. The purpose this study was identify optimal trade-off between number viewpoints needed generate an accurate viewshed for given route. In study, we focused on identifying how...

We present an approach to determine the credibility of content provided within a visual VGI source such as Flickr. We propose analysing the variability of selected user and photo metadata of geotagged Flickr photos with the location correctness of these images, which is our reference quality measure. These observed user and photo metadata can help to infer the credibility of contributors.

With the increased availability of user generated data, assessing the quality and credibility of such data becomes important. In this article, we propose to assess the location correctness of visually generated Volunteered Geographic Information (VGI) as a quality reference measure. The location correctness is determined by checking the visibility of the point of interest from the position of t...

The Battle of Midway (June 4 – 6, 1942) is considered one of the pivotal naval encounters of the Second World War. The battle has been examined in detail within both popular and scholarly literature, and a common opinion found in virtually all of these examinations is that Japanese search efforts on the morning of June 4, which were intended to determine if any U.S. naval forces were present, w...

Abstract Relationships between body shape and escape performance are well established for many species. However, organisms can face multiple selection pressures that might impose competing demands. Many fishes use fast starts escaping predator attacks, whereas some species of gobiid have evolved the ability to climb waterfalls out predator-dense habitats. The ancestral ‘powerburst’ climbing mec...

BACKGROUND The influence of visual exposure to health-related behaviours, such as smoking, is increasingly acknowledged in the public health literature. Social contagion or normalisation is thought to operate through the visibility of those behaviours. There has been a lack of systematic and comprehensive approaches to quantifying visual exposure to these behaviours over a relatively large geog...

A lot of research has been conducted on achieving realistic fluid simulations: waves, flow, waterfalls, etc. This paper focuses on a less talked about aspect of fluid simulation: the behavior of liquids in zero gravity. Unlike in most other situations which are dominated by gravity, surface tension becomes the key phenomenon of the simulation. A spring-connected system of particles is used to m...

Diatoms are mostly aquatic plants, growing in various environmental conditions and habitat. Because of their high sensitivity to variations rapid response degradation, they used as biological indicators. This study aimed analyses the physicochemical parameters diatoms assemblages waterfalls. will allow determining key factors that responsible for both Podostemaceae spatial temporal distribution...
