Geographic information system (GIS) refers to a system that is designed to capture, store, manipulate and analyse geographical data. This type of information system is used for planning and designing layout for land use and management. The data collected and stored by the GIS can be used for varied purposes ranging from transport, disease-outbreak analysis, draught analysis, land occupancy, etc.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
