Accessibility to goods and services is a complex notion which completely pervades territorial issues. Some aspects of accessibility are related to physical features and could be expressed using measurement units. Others are related to preferences that depend on values shared among people belonging to various social groups. These values are related to their specific constraints including economi...

Current work in modeling has focused on fuzziness as it applies to single entities. An application of fuzzy theory may be made to managing data sets and collections, thus treating the data sets as collection of fuzzy objects. The application of fuzzy theory to management of sets creates has not been fully explored. In the area of Geospatial Information Science (GIS), one can find many types of ...

This paper presents the methodology developed for the SOLARGIS project an EU JOULE project for the integration of renewable energies in dispersed electricity production, supported in a GIS platform. The paper discusses the methodologies for the assessment of the efficiency and market of isolated system for dispersed rural electrification. The models form a mix use of probabilistic and fuzzy set...

Land suitability evaluation in water scarce agricultural watersheds consists of assessment of land potential for various crops as well as surface water potential to identify the scope for supplementary irrigation. A large amount of information related to the crop land suitability can be conveyed through linguistic terms. Capability of fuzzy sets in modeling involving uncertainty and vagueness i...

Topological relations are one of the most fundamental properties between spatial objects. The topological relations between crisp spatial objects have been well identified. However how to formalise the topological relations between fuzzy regions needs more investigation. The paper starts from introduction of boundaries defined in the fuzzy topological space. By use of a definition formally equi...

the success of artificial recharge schemes requires the identification of suitable site. the use of fuzzy set theory in site selection projects allows the decision-makers to incorporate unquantifiable information into decision model. in this paper, site selection of artificial groundwater recharges using an integrated method of fuzzy topsis and ahp has been done in raster environment of gis. th...

The rapid development of computers and associated software during the last thirty years has led to the expansion (emergence) of Geographical Information Systems (GIS). Geographical information systems (GIS) are computer-based systems designed specifically to facilitate the digital storage, retrieval, and analysis of spatially-referenced environmental data. Coupled with ecological modelling, GIS...
