relative accuracy
[accuracy] A measure of positional consistency between a data point and other, near data points. Relative accuracy compares the scaled distance of objects on a map with the same measured distance on the ground.
Relative Accuracy
Accuracy of these maps is determined by the mapmaker and the value of this accuracy is judged by the user of the map. For simple directions, a user may not value extreme accuracy.
relative accuracy The degree to which map features are shown with the correct distances and directions from each other.
Relative accuracy is basically a measure of the normal deviation between two objects on a map and is normally described in terms of + or - the number of measurement units (normally inches or feet) the feature is located apart from its neighboring map ...
The relative accuracy of height values resulting from the global-geopotential-model method are dependent on the grid spacing of the geopotential model used.
The grouping of observations into control and check points is useful for estimating the relative accuracy of the geometric transformations.
Relative accuracy is a measure of the accuracy of individual features on a map when compared to other features on the same map.
Different maps differ in the relative accuracy of the depiction of the area, the shapes of objects, actual distances, and compass direction.
DOP: Dilution of Precision is a term used to describe the relative accuracy of a GPS position.
When satellites are spread across the sky far from each other, the triangulation calculations result in precise locations.
Without an understanding of the relative accuracy and interpolation error of the base maps, one cannot be sure of the recommendations and decisions derived from the interpolated data.
Striking a balance: absolute and relative accuracy within a utility GIS

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.
A measure of the geometric quality of a GPS satellite configuration in the sky. HDOP is a factor in determining the relative accuracy of a horizontal position. The smaller the DOP number, the better the geometry.
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 ...
According to the information provided by NIMA, the model has the absolute accuracy of 30m, while the relative accuracy is better than 20m.
With this application, measurement-based land records are efficiently used to maintain parcels and related features, supporting a single standard of absolute and relative accuracy across all your GIS data.
land use and/or infrastructure master plans, or environmental impact assessments. A recommended standard in this case would be all control points having an absolute accuracy of 5 feet or better and all referenced points having a relative accuracy of ...
