Overview: The validity of a decision is a function of the reliability of the data from which it is derived. Spatial data now plays a core activity in most, if not all organizations. GIS derived results invariably impact negatively or positively on operational and planning decisions. Logically this implies that careful use of GIS-supplied information requires an accuracy assessment of all data involved. This paper from International Federation of Surveyors explores a cognitive process, the balance (or trade - off) effect that has been shown to influence good decision-making. A brief analysis of elements of data quality is given.
