Geographical Information System (GIS) applications that process large amount of data require intensive usage of hardware capabilities provided by distributed platforms, such as the Grid infrastructure. Due to the constant demand of data availability and data sharing, without concerning its format and size, a new software solution is needed. GreenLand is a system capable to provide such a soluti...

When facing local environmental issues, maps are a very effective tool. They can help in collecting facts about an area, bring issues to the table, allow for comparison between areas, act as a tool of communication with local decision makers, and identify key issues for action. While the maps on their own do not alter the power relationships within which communities live their lives, many studi...

In 1997 the National Science Foundation launched the Varenius Project with the aim of advancing geographic information science (Goodchild et al., 1999). Varenius incorporated three components: computational, cognitive, and societal. In a review paper titled “Geographies of Information Society,” Sheppard et al. (1999) explored the third (societal) component with the aim of introducing the key re...

Nowadays the use of remote sensing and Geographic Information System (GIS) is one of the most powerful cost effective tools to identify and discover the available groundwater resources. In this paper, Lithological Units, Lineaments, Slope, Topography, Drainage density, Vegetation and Isohyets lines have been achieved by stations and through remote sensing and GIS techniques. All layers of diffe...

Introduction: Soil has an important role in nutrient cycle and an important function in storage, refinement, and movement of nutrients for the living and non-living parts. Soil pollution of heavy metals and elements is one of the common pollution impacts of human activities, especially industry. Realization of distribution pattern of these elements and their anthropogenic sources is a major par...

This research presents the geotechnical zoning map of district 1 in Shiraz municipality with focus on municipal deep excavation hazard assessment on data from 160 boreholes. For this purpose, the mechanical properties are determined according to the results of direct shear, uniaxial, and SPT tests and then excavation hazard assessment with depths of 3, 6 and 9 m, in situations where the excavat...

The understanding of inland wetlands’ distribution and their level of vulnerability is important to enhance management and conservation efforts. The aim of the study was to map inland wetlands and assess their distribution pattern and vulnerability to natural and human disturbances such as climate change (temperature increase) and human activities by the year 2080. Inland wetland types i.e. for...
