to evaluate land suitability of aq-qalla region for rainfed chickpea cropping, boolean logic and analytical hierarchy process (ahp) methods were used in geographic information system (gis). to achieve this, firstly, climatic and agronomical requirements of chickpea,were identified according to scientific resources. then, thematic requirement maps were provided. the studied environmental-compone...
the primary objective of the current study is to produce karstification potentiality maps in northeast of khuzestan province, iran, using both fuzzy logic and ahp models as an additional tool in hydrogeological research. geographic information systems (gis) and remote sensing (rs) are used to create two maps depicting the development of the karstification, consisting of five classes, showing th...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
An intelligent geoportal orchestrates (automatically coordinate) web services to prepare, discover and present information to the user. Implementations of web service standards by the Open Geospatial Consortium (OGC) and ISO/TC 211, Geographic information/Geomatics, such as, the Web Map Service (WMS), Web Feature Service (WFS) and Styled Layer Descriptor (SLD) enable the display of spatial data...
ii abstract the legend of human being’s refulgence was distorted completely in the age of modernity. this new age, had some drastic negative effects, besides its positive qualities. one significant negative effect of it was the emergence of neurosis in human beings. aldous huxley’s brave new world was one of the novels of the 02 th century that contained the prophecy of criticizing ...
Soil erosion and sedimentation processes can be considered as serious eco-environmentalproblems. This study aimed to estimate the basin-wide erosion using the Revised UniversalSoil Loss Equation (RUSLE). The soil erosion parameters included rainfall erosivity mapgenerated from the rainfall data, soil erodibility extracted from the soil map, land cover andmanagement map produced from supervised ...
To be successful in tree establishment, an assessment of land suitability would be necessary. The aim of this study was determining the potential habitats of three native tree species (Quercus persica, Pistacia atlantica, Amygdalous scoparia) in Siahkoh region of Ilam County, using Boolean method and Geographic Information Systems (GIS). For this regard, the slope, aspect and hypsometric maps o...
The notion of an object bearing information is central to the traditional situation semantics framework. Herein, this notion is extended to the realm of thematic maps as a vehicle for the formalization of their thematic content. Maps are the most acknowledged graphic representations of spatial phenomena. In the light of Situation Theory, we apply its evolution theory; Information Flow, to exami...
