The problems of land degradation and soil loss are among the major problems of watersheds in Iran. For erosion and sediment estimation one can use statistical and empirical methods. For doing this, land unit map and the map of effective factors should be prepared. For erosion and sediment estimation one can use statistical and empirical methods. However, these empirical methods are usually time...

ABSTRACT. ––Land suitability assessment in a Geographic Information System (GIS) environment is formulated as a multi-criteria decision making (MCDM) problem. Different MCDM approaches are developed to combine factors in a suitability analysis of land for potential land uses. These MCDM approaches are used to develop a generic suitability index. Approaches include both qualitative and quantitat...

various criteria are involved impacting trend of art and literature in a society. socio-political infrastructure and changes within it are of the parameters affecting literature in a society. in 19th century in iran, literature and poetry in particular was reformed fundamentally under impact of socio political structure. courtier poetry was replaced by practical protest one to achieve this whil...

The evaluation of land quality plays an important role in the study of land resources. Some software of GIS was applied to evaluate land quality in recent years. There is some limitation in Appling GIS to evaluate land quality directly. GIS combined with MCE (Multi-Criteria Evaluation) can eliminate limitation existing in using GIS singly. In this thesis key technology of evaluating land qualit...

Information quality (IQ) is one of the most important aspects of information integration on the Internet. Many projects realize and address this fact by gathering and classifying IQ criteria. Hardly ever do the projects address the immense difficulty of assessing scores for the criteria. This task must precede any usage of criteria for qualifying and integrating information. After reviewing pre...

The assessment of Small Hydro Power (SHP) sites for project planning and development represents a relatively high proportion of overall cost. A high level of experience and expertise is required to accurately conduct this multidimensional assessment at both pre-feasibility and feasibility analysis stage. A variety of multi-criteria decision analysis or making (MCDA or MCDM) methods as well as c...

Formal methods are mathematical techniques use in design, development and verification of software and hardware system. Geographic information systems GIS use to collect, store, analyze and present spatial informations. GIS databases are usually very complex to design. Formal methods can play an important role in their design. In the paper, the authors investigate an approach of formal specific...

Land allocation priorities to urban green cover are usually neglected particularly in the countries of developing economies such as Turkey. Lack space can cause many social and physical problems among residents. Therefore, planning policy should incorporate suitable land cities optimise benefits obtained from spaces. suitability analysis is a commonly used methodology which provides framework f...
