assessing the quality of groundwater is important to ensure the sustainablesafe use of these resources. however, describing the overall water quality condition isdifficult due to the spatial variability of multiple contaminants and the wide range ofindicators (chemical, physical and biological) that could be measured. therefore, in thiscase study, some water quality parameters including na, mg,...

strategic environmental assessment can be viewed as a process to integrate the concept ofsustainable development into planning. in this context, sea can be regarded as a method that regulates theplanning process to a state of sustainable development. however, to reach that goal it is necessary to achieve full integration of planning and the sea process.therefore this paper considers the integra...

Introduction Geographic information systems (GIS) are not exactly new to the social sciences—the UK's Economic and Social Research Council funded a network of GIS-based laboratories at UK universities in the late 1980s and early 1990s, and the U.S. National Science Foundation's Directorate for Social, Behavioral, and Economic Sciences funded the National Center for Geographic Information and An...

Web-based geographic information system (GIS) technology, or web-based GIS, offers many opportunities for public planners and Extension educators who have limited GIS backgrounds or resources. However, investigation of its use in planning has been limited. The study described here examined the use of web-based GIS by public planning agencies. A 2013 web-based survey of 274 public planning agenc...

BACKGROUND Despite the demonstrated utility of GIS for health applications, there are perceived problems in low resource settings: GIS software can be expensive and complex; input data are often of low quality. This study aimed to test the appropriateness of new, inexpensive and simple GIS tools in poorly resourced areas of a developing country. GIS applications were trialled in pilot studies b...

Background: Land use suitability assessment is a key factor in any urban and suburban planning and decision-making processes. The assessment is evaluated by a series of criteria involving socio-economic needs. To deal with the conflicting, disproportionate and multiple criteria, land usage will be characterized with respect to the preferences and importance. Meanwhile, many spatial decision pro...

Since 1996 GRASS is used in GIS classes at the Dipartimento di Ingegneria Civile ed Ambientale of the Università di Trento. This paper describes the potential of this GIS, with freely available code, in Geographical Information Systems education, both for university courses and professional training. The use of GRASS offers several advantages: the software is accessible without licensing worrie...

The building of virtual reality system for the opencast mine is a complicated and systemic project. The building process of virtual system includes data collection, GIS geodatabase, model designing and raster textures making. GIS data is from field survey, maps, and remote sensing images. The import phase is the building of kinds of models in different environment. This paper introduced several...

In this paper I will show how social network analysis techniques can be used for understanding GIS diffusion at a national scale. In particular, two network models, cohesion and structural equivalence, are explored in the context of the emerging Greek GIS community. A map of this community based on GIS teams and linkages is put forward, and two social constructs, institutional setting and disci...
