Land use/cover change is a major global environmental change issue and projecting these changes is essential for the assessment of environmental impacts. In this study, a combined use of satellite remote sensing, geographic information systems (GIS), and markov chains stochastic modelling techniques were employed in analysing and projecting land use/cover changes. The results indicate that ther...

The aim of the present study was to identify geographical areas and time periods of potential clusters of dengue cases based on ecological, socio-economic and demographic factors in northern Sri Lanka from January 2010 to December 2013. Remote sensing (RS) was used to develop an index comprising rainfall, humidity and temperature data. Remote sensing data gathered by the AVNIR-2 instrument onbo...

Increasing frequency and quality of remote sensing observations created strong demand for high-quality retrieval of thematic information as input for analysis, modeling and decision-making purposes. Furthermore there is growing need to integrate the processes associated with analysis of remote sensing imagery into the workflow of landscape management systems. To meet those demands, research has...

This paper describes a methodology for modelling light pollution using geographical information systems (GIS) and remote sensing (RS) technology. The proposed approach attempts to address the issue of environmental assessment in sensitive suburban areas. The modern way of life in developing countries is conductive to environmental degradation in urban and suburban areas. One specific parameter ...

Introduction: Geographic information systems (GIS), and more specifically remote sensing, have been used within the geosciences for well over two decades. In that time, the ability to handle a variety of increasingly voluminous data (both vector and raster) has allowed continued data analysis and exploitation within mainstream GIS. The uptake and use of GIS has not been mirrored within the plan...

ABSTRACT: GIS can significantly contribute to correct interpretation of the signatures of slicks visible on synthetic aperture radar (SAR) images, providing a basis for analysis. Proposed geoinformation approach to oil spill mapping is presented. It includes integration of the geographical, remote sensing, oil & gas infrastructure data and slick signatures, detected in SAR images, in GIS. Vario...

Soil is one of the most important natural resources covering a large area of the land surface. Soil plays a vital role in biosphere processes, such as energy balance, hydrology, biochemistry, and biological productivity. It supports plants that supply foods, fibers, drugs, and some other human needs. Conversely, desert regions include about one third of earth lands and these regions have increa...

This Methodolical Review describes how health geomatics can improve our understanding of the important relationship between location and health, and thus assist us in Public Health tasks like disease prevention, and also in better healthcare service planning. The reader is first introduced to health geography and its two main divisions, disease ecology and healthcare delivery, followed by an ov...

Background: Since hurricane Katrina, developer and planners are looking at a tools and sustainable ways to minimize vulnerabilities in events of disasters especially along the coast. In this setting, remote sensing and Geographic information systems (GIS) have the capacity to provide valuable and timely information about coastal resources, and form an important basis for sustainable planning fo...
