More About GIS Error, Accuracy, and Precision | GEOG 469

The Importance of Error, Accuracy, and PrecisionSome Basic DefinitionsTypes of ErrorSources of Inaccuracy and ImprecisionThe Problems of Propagation and CascadingBeware of False Precision and False Accuracy!The Dangers of Undocumented DataUntil quite recently, people involved in developing and using GIS paid little attention to the problems caused by error, inaccuracy, and imprecision in spatial datasets. Certainly, there was an awareness that all data suffers from inaccuracy and imprecision, but the effects on GIS problems and solutions was not considered in great detail. Major introductions to the field such as C. Dana TomlinGeographic Information Systems and Cartographic Modeling (1990), Jeffrey Star and John EstesGeographic Information Systems: An Introduction (1990), and Keith ClarkeAnalytical and Computer Cartography(1990) barely mention the issue. This situation has changed substantially in recent years. It is now generally recognized that error, inaccuracy, and imprecision can "make or break" many types of GIS projects. That is, errors left unchecked can make the results of a GIS analysis almost worthless. The irony is that the problem of error is it devolves from one of the greatest strengths of GIS...Get price
