The balance between data quality and user's information needs : thinking strategically for rational decision-making
Chigiinge, Francis
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 organisations. 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. Furthermore, the accuracy and quality of data required for different applications is not usually homogeneous, implying that there is a general lack of specified standards of accuracy in GIS data. This calls for the need to determine the reliability of data, which can conveniently be done through considerations of data quality versus the userrs needs. Arriving at a useful, meaningful decision will depend on striking a convenient balance between data quality and userrs needs. This paper 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.
