OBJECTIVE To develop and map indices to illustrate variation in the cost and availability of healthy food. DESIGN Two contiguous wards in London were selected by virtue of their high Carstairs deprivation scores. A 2-km area was defined around a randomly chosen central point. All retail outlets selling food within the area were visited and their location recorded. A list of foods, acceptable ...

This paper introduces an urban simulation model for environmental health analysis (SIENA). SIENA is a novel tool to explore urban interactions and processes with regard to exposure assessments. It is based on urban structures and relationships observed in real-world cities making it a realistic representation of a functioning city. The development of SIENA involved identifying and quantifying f...

news. If you create conditions incompatible with life, the program lets you know your patient is dead, this is the MacMan equivalent of crashing your airplane in a flight simulator, and should this happen you merely start again, because there is no equivalent to reversing the program and resurrecting the dead. Some of the experiment options include: cutting the buffer nerves, resetting barorece...

Purpose – The purpose of this paper is to provide an overview of free and open source (FOSS) geographic information system (GIS) software within the broader contexts of the open source software movement and developments in GIS, and pose the question of whether libraries and academic departments should consider adopting FOSS GIS. Design/methodology/approach – The process of creating a basic them...

This chapter presents a programming-by-demonstration (PBD) approach to Geographical Information Systems (GIS). The aim of our approach is to enable non-specialist users to avail themselves of the software without having to resort to the help of expert users. We begin with a story of one group of non-specialist users who encountered difficulty with GIS software. Next we summarize findings of a s...

GIS (Geographic Information System) usability is one of the most significant factors of government sectors like the Ministry of Environment, Planning, Forestry, Fisheries, and so on. In this paper, we present a methodology for evaluating the usability of GIS software. We demonstrate how to find out the severity ratings of problems in GIS software. A sample GIS user Interface prototype is design...

The purpose of this paper is to develop the GIS educational environment in training program using open-source GIS software. First, we have verified the substitutability of laboratory exercise materials at our university from commercial GIS to open-source GIS software. Next, we grasp the improvement situation of the free spatial data that are opened to the public by the government and present th...

BACKGROUND Tuberculosis (TB) spread pattern is influenced by geographic and social factors. Nowadays Geographic Information System (GIS) is one of the most important epidemiological instrumentation identifying high-risk population groups and geographic areas of TB. The aim of this study was to determine the correlation between climate and geographic distribution of TB in Khuzestan Province usin...
