[coordinate systems] The degree to which the position of an object on a map conforms to its correct location on the earth according to an accepted coordinate system.
Absolute Accuracy: Exact correspondence between the location of features in map data and their actual positions on the earth.
Refers to the position of an object position in relation to a control survey network. (See also Accuracy and Compare with Relative Accuracy.)
Absolute Coordinate ...
Absolute accuracy refers to the relationship of a point in the database to its actual location on the globe.
Relative accuracy refers to the relationship of one point in the database to another point in the same database.
The degree to which the position of an object on a map conforms to its correct location on the earth according to an accepted coordinate system.
This absolute accuracy estimate assumes that the fixed (existing) control is superior to the survey being performed and that any position misclosures at connecting points are due to internal observational errors and not the existing control.
Absolute accuracy is a measure of the location of features on a map compared to their true position on the face of the Earth.
It is not used in situations where absolute accuracy is required. However, it does produce a compromise image which minimizes distortions in area, direction, and distance and therefore gives an excellent overall sense of the area being mapped.
Closeness of results of observations, computations, or estimation of spatial features to their true value of position. "Absolute Accuracy" is the differential between the actual real world location of a point on the surface of the earth and its ...

According to the information provided by NIMA, the model has the absolute accuracy of 30m, while the relative accuracy is better than 20m.
When data is captured, the user should consider if the data should be captured with either a relative accuracy or absolute accuracy, since this could not only influence how information will be interpreted but also the cost of data capture.
accuracy, absolute The accuracy of a map in representing the geographic location of an object relative to its true location on the surface of the Earth. Absolute accuracy is based on geographic coordinates.
