Designing a GIS data model that can help analyze spatial and temporal patterns and interactions of human activities presents a challenging research topic. Due to a growing adoption of information and communication technologies (ICTs) in today’s society, an increasing number of human activities are performed in the virtual space. This paper presents a spatio-temporal GIS design to support explor...

We devised software tools to systematically investigate the contents and contexts of bacterial tRNA and tmRNA genes, which are known insertion hotspots for genomic islands (GIs). The strategy, based on MAUVE-facilitated multigenome comparisons, was used to examine 87 Escherichia coli MG1655 tRNA and tmRNA genes and their orthologues in E.coli EDL933, E.coli CFT073 and Shigella flexneri Sf301. O...

This study combines two luminous areas, geographical information systems ~GIS! and E-commerce system, and applies the combined technology in the business of construction material trading. In the era of electronic business, trades can be accomplished without limitations on time and space. The statement is true in principle only, but in reality, any kind of business activity must involve transpor...

TLA geographical information system (GIS) is a digitalised mapping process in which data from topographical maps, remote sensing satellite imagery, high-altitude photographs and other maps can be layered and analysed. GIS has been applied to a number of research disciplines because it is an effective means of relating data to geography. An important advantage of using GIS is that layers of unre...

Computer tools for spatial analysis of plant genetic resources data: 1. DIVA-GIS The DIVA-GIS software allows analysis of genebank and herbarium databases to elucidate genetic, ecological and geographic patterns in the distribution of crops and wild species. It useful for scientists who cannot afford generic commercial GIS software, or do not have the time to learn how to use it, and for others...

Geographic information systems (GIS) are being used with increasing frequency in environmental epidemiology studies. Reported applications include locating the study population by geocoding addresses (assigning mapping coordinates), using proximity analysis of contaminant source as a surrogate for exposure, and integrating environmental monitoring data into the analysis of the health outcomes. ...

This paper focuses on the use of geographic information system (GIS) in gender research and argues for the possibility that the tool has inherent biases with regard to data collection and representation. Introduction Given the mandate by large agencies to address gender in all development projects and the „Mainstreaming of Gender‟ at the World Bank, we can expect that new opportunities will eme...

Our objective in this paper is to argue for a new use of geographic information systemsö GIS in local planning as an auxiliary tool for decisionmaking. We review the use of the GIS technique in earlier research studies and represent the empirical findings from using GIS in a quality-of-life study in conjunction with an urban renewal project of a residential area in Stockholm County, Sweden. Spe...

1. Introduction Since early '90 GIS has become a sophisticated system for maintaining and analysing spatial and thematic information on spatial objects. The need for 3D information is rapidly increasing. 2D GIS analysis has shown its limitations in some situations, e.g. noise prediction models (noise spreads out in three dimensions) (Kluijver and Stoter, 2003), water flood models, air pollution...

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...
