In an effort to contribute to the conceptualization of the burgeoning field of Volunteered Geographic Information (VGI), we propose to review selected definitions and debates around Geographic Information Systems (GIS). “Traditional” geographic information emerges from the interplay of the components of GIS: hardware, software, data, and application, and it is shaped by the processing of geogra...

Objective: To identify the spatial distribution and prevalence of speech disorder in Iran. Materials and methods: First, the prevalence of speech disorder in 2006 and 2011 was mapped via GIS for each province. Moreover, the prevalence of this disorder was calculated and classified according to age, sex, and residential area. Results: The prevalence in the majority of provinces indicated an over...

GIS elemental unit representations of spatial data are often defined in terms of points, lines and areas. However, another type of spatial data that is becoming frequently captured, but as yet is largely ignored in GIS, is that of video. While digital video recording is a commonly encountered medium in modern society and encompasses many forms, from simple personal camcorders through to sophist...

GIS managers traditionally consider three perspectives of the nature of GIS when introducing GIS into an organization. When the GIS is developed to address focused and well de® ned problems of the organization, these perspectives adequately describe the changing identities of GIS in the study of its di€ usion. However when the GIS is developed to address strategic, but vaguely de® ned problems,...

The Paraffin Safety Association (PASASA) of Southern Africa is a non-profit organisation established in 1996 to ensure that paraffin/ kerosene use is safe for low-income households. PASASA achieves this through strategic partnerships, research and promotion of safe practices through health education and policy interventions. One of the many challenges that PASASA is trying to overcome is the la...

Between 2006 and 2012, a rabies control programme has been conducted in the area of Lake Turkana in northern Kenya. Spatial data obtained for this project were analysed with the aim of assessing the importance of dog home ranges with the view of possible overlapping between dog populations from adjacent localities. In contrast to our expectation of the maximum home ranges of dogs in the harsh s...
