To be able to utilise geographical data for analysis, one should know something about the quality of the data. In present geographical data standardisation proposals (SDTS, CEN TC287), several aspects of geographical data quality have been described, such as lineage (data collection and processing history), spatial accuracy, attribute accuracy, completeness, logical consistency and currency. Me...

Voronoi diagram on the earth surface is a powerful tool to study spatial proximity at continental or global scale. However, its computation remains challenging because geospatial features have complex shapes. This paper presents a raster-based algorithm to generate Voronoi diagrams on earth's surface. The algorithm approximates the exact point-to-point geographical distances using the cell-to-c...

Ecological destruction in human-dominated landscapes has significant impacts on environment sustainability internationally. Landscape planning can play a role in mitigating the effects of human-related activities. One element of landscape planning involves the analysis of the biological, spatial and social arrangement of areas in an urban environment and identifying characteristics that are und...

In this paper a coarse classification scheme is proposed to speed up the recognition process of machine printed Chinese character. Simple and stable features are extracted by encoding feature points into a codeword of length 16. Geometrically, the codeword represents the distribution of feature points among character strokes. Using these simple features to do coarse classification can eliminate...

Landscape features have been shown to strongly influence dispersal and, consequently, the genetic population structure of organisms. Studies quantifying the effect of landscape features on gene flow of large mammals with high dispersal capabilities are rare and have mainly been focused at large geographical scales. In this study, we assessed the influence of several natural and human-made lands...

It holds true that a flourishing fieldof Contrastive Rhetoric (CR) research has begun to address theway various text types and/or genres may differ across culturesand languages (Corner, 1996).  Very much in line withthis development, this study was an attempt to characterizethe linguistic structures of headlines in the sports section of 2 English newspapers: one non-Iranian (The Times) and one ...

OBJECTIVE While SLE is found worldwide, there is diversity in clinical presentation of the disease according to geographical variations. The aim of this study is to describe geographical distributions of childhood onset SLE within Oman to identify geographical clustering and to compare the demographic, clinical, and immunological characteristics of this cluster against the rest of Oman. METHO...
