    Accuracy Versus Precision; The Target AnalogyQuantifying Accuracy and PrecisionAccuracy and Precision in Binary ClassificationAccuracy and Precision in Psychometrics and PsychophysicsAccuracy and Precision in Information SystemsSee AlsoReferencesExternal LinksAccuracy is the degree of veracity while precision is the degree of reproducibility.[citation needed]The analogy used here to explain the difference between accuracy and precision is the target comparison. In this analogy, repeated measurements are compared to arrows that are shot at a target. Accuracy describes the closeness of arrows to the bullseye at the target center. Arrows that strike closer to the bullseye are considered more accurate. The closer a systemmeasurements to the accepted value, the more accurate the system is considered to be. To continue the analogy, if a large number of arrows are shot, precision would be the size of the arrow cluster. (When only one arrow is shot, precision is the size of the cluster one wouldexpect if this were repeated many times under the same conditions.) When all arrows are grouped tightly together, the cluster is considered precise since they all struck close to the same spot, if not necessarily near the bullseye. The measurements are...

  • DATA ACCURACY AND QUALITY

    AccuracyQualityPositional AccuracyAttribute AccuracyLogical ConsistencyCompletenessErrorThe fundamental issue with respect to data is accuracy. Accuracy is the closeness of results of observations to the true values or values accepted as being true. This implies that observations of most spatial phenomena are usually only considered to estimates of the true value. The difference between observed and true (or accepted as being true) values indicates the accuracy of the observations. Basically two types of accuracy exist. These are positional and attribute accuracy. Positional accuracyis the expected deviance in the geographic location of an object from its true ground position. This is what we commonly think of when the term accuracy is discussed. There are two components to positional accuracy. These are relative and absolute accuracy. Absolute accuracy concerns the accuracy of data elements with respect to a coordinate scheme, e.g. UTM. Relative accuracyconcerns the positioning of map features relative to one another. Often relative accuracy is of greater concern than...

    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...
