One of the main objectives of this family of standards is to
enable geographic data to be shared and widely available in and
across application domains. As this objective becomes realised
it will increasingly be important to data users to determine fitness
for use. Part 13 provides guidelines to data producers for describing
the quality of their data; the quality information may be used
by data users attempting to determine whether or not specific
data is of sufficient quality for their particular application.
Two components of data quality are identified. Data quality overview elements providing informative non-quantitative information that may be subjectively evaluated, and data quality elements providing quantitative quality information that reports how well a dataset meets the criteria set forth in its product specification. Data quality elements include the quality components of completeness, logical consistency, positional accuracy, temporal accuracy, thematic accuracy and allow for the creation of additional user defined components. Each component is comprised of several aspects called data quality sub-elements. Data quality information for each data quality sub-element is reported in several parts, including a data quality scope, data quality measure, data quality evaluation procedure, data quality result, data quality value domain, and data quality date.
The metadata schema given in 15046-15 is the mandatory method for reporting data quality information.
