Abstract:
The information technology has developed manifolds, especially in last one decade. The base of any information technology depends largely upon the information inputs in form of a database and its suitable use. Large data sets can be handled on computers under the Data Base Management System using various softwares, however, these softwares can only tackle non-spatial data. To extract selective information relevant to the planning task with reference to the geo-referenced location, analyses of different thematic maps (spatial information) and integration of large amount of attribute data (non-spatial information) is required. This is possible through a comparatively new and sophisticated information technology, known as the Geographic Information System. This paper describes the underlying concepts and basics of Geographic Information System.
