Data quality and positional accuracy.
Metadata object are described in the OpenGIS® Metadata (Topic 11) specification. The following table shows the class hierarchy, together with a partial view of aggregation hierarchy:
Interface Summary Interface Description AbsoluteExternalPositionalAccuracyCloseness of reported coordinate values to values accepted as or being true. AccuracyOfATimeMeasurementCorrectness of the temporal references of an item (reporting of error in time measurement). CompletenessPresence and absence of features, their attributes and their relationships. CompletenessCommissionExcess data present in the dataset, as described by the scope. CompletenessOmissionData absent from the dataset, as described by the scope. ConceptualConsistencyAdherence to rules of the conceptual schema. ConformanceResultInformation about the outcome of evaluating the obtained value (or set of values) against a specified acceptable conformance quality level. CoverageResultResult of a data quality measure organising the measured values as a coverage. DataQualityQuality information for the data specified by a data quality scope. DomainConsistencyAdherence of values to the value domains. ElementType of test applied to the data specified by a data quality scope. FormatConsistencyDegree to which data is stored in accordance with the physical structure of the dataset, as described by the scope. GriddedDataPositionalAccuracyCloseness of gridded data position values to values accepted as or being true. LogicalConsistencyDegree of adherence to logical rules of data structure, attribution and relationships. NonQuantitativeAttributeAccuracyAccuracy of non-quantitative attributes. PositionalAccuracyAccuracy of the position of features. QuantitativeAttributeAccuracyAccuracy of quantitative attributes. QuantitativeResultInformation about the value (or set of values) obtained from applying a data quality measure. RelativeInternalPositionalAccuracyCloseness of the relative positions of features in the scope to their respective relative positions accepted as or being true. ResultBase interface of more specific result classes. ScopeDescription of the data specified by the scope. TemporalAccuracyAccuracy of the temporal attributes and temporal relationships of features. TemporalConsistencyCorrectness of ordered events or sequences, if reported. TemporalValidityValidity of data specified by the scope with respect to time. ThematicAccuracyAccuracy of quantitative attributes and the correctness of non-quantitative attributes and of the classifications of features and their relationships. ThematicClassificationCorrectnessComparison of the classes assigned to features or their attributes to a universe of discourse. TopologicalConsistencyCorrectness of the explicitly encoded topological characteristics of the dataset as described by the scope. Usability Deprecated.Not found in ISO 19115-3:2016 schemas.
