Abstract

The graphical information system (GIS) is based on the distinction between data and information; data are collected facts, but information is only that data useful for a particular purpose and perceived as such by the user. The GIS increases both relevant information and its perception. The GIS is effectively used in semistructured decisions where it enhances the ability of the user to apply creativity and judgment in solving novel problems. An example illustrates the potential of the GIS to convey patterns, trends, and relationships, thereby enhancing the ability of the user to filter relevant information from extraneous data. Several graphic profiles of a bus route are contrasted with the corresponding tabular summary. All are derived from the same data, but because of data format they convey significantly different information.
