Saddled with the burden of increasing poverty among majority of their populace, many African countries are initiating various Poverty Alleviation Programmes (PAP). Many of these programmes however miss out the influence of geography and spatial variables as determinants of poverty, that is, the spatial dimension of the problem of poverty. Attempts are increasing being made to use GIS for povert...

numerous algorithms have been proposed to solve the shortest-pathproblem; many of them consider a single-mode network and crispcosts. other attempts have addressed the problem of fuzzy costs ina single-mode network, the so-called fuzzy shortest-path problem(fspp). the main contribution of the present work is to solve theoptimum path problem in a multimodal transportation network, inwhich the co...

In the broad area of life sciences Landscaping can minimize the visual and physical impact of a building or development through masking the bulk and scale, and affect the microclimate, such as reducing the heat of the summer sun and absorbing storm water. A good understanding of the site and its surrounds is essential for a successful landscape design. Site analysis puts the site in its context...

How to build an image interpretation expert system and other relevant expert systems within a knowledge-based pictorial information system is an ad hoc theme in geographical information system(GIS) field. It plays an important role in building a synthetic information system and in enhancing the GIS system performance. In this article, we present a forestry regional resource planning sub-system,...
