There has been a rapid expansion in the range of applications utilizing sophisticated geographic information systems. These expanding applications have spawned a parallel increase in demands for information regarding the "quality' of the data in the information system. Initially this concern has focused on the products of government organizations such as Statistics Canada, and the response has been to determine some level of confidence in the accuracy of the digital position of the points. While the positional accuracy of points is important, it is not a sufficient measure of accuracy for all applications. A range of accuracy issues exists, with the complexity of these issues inextricably related to the complexity of the information being extracted directly from the GIS, or indirectly through post processing. -Authors
