Introduction to GIS © 2007 Austin Troy Source: adapted from UC Berkeley GIS Center What is GIS? (some boring definitions) The complete sequence of components for acquiring, processing, storing and managing data (Star and Estes, 1990) It is a configuration of computer hardware and software specifically designed for the acquisition, maintenance and use of cartographic data, (Tomlin, 1990) It is a set of computer tools for collecting, storing, retrieving at will, transforming and displaying spatial data from the real for a particular set of purposes, (Burrough et al. 1998) A system of hardware, software, data, people, organizations and institutional arrangements for collecting, storing, analyzing and disseminating information about areas of the earth.
