Interface AccuracyOfATimeMeasurement

All Superinterfaces:

Element, TemporalAccuracy, TemporalQuality

@UML(identifier="DQ_AccuracyOfATimeMeasurement",
     specification=ISO_19157)
public interface AccuracyOfATimeMeasurement
extends TemporalQuality, TemporalAccuracy

Correctness of the temporal references of an item (reporting of error in time measurement).

Standardized values

In order to achieve well defined and comparable quality information, it is recommended to report data quality using quality measures listed in ISO 19157 annex. The following table provides a summary adapted to GeoAPI objects; see ISO 19157 for more complete descriptions and formulas. All identifiers should be in "ISO 19157" namespace.

Standardized values derived from ISO 19157

Identifier	Name of measure	Basic measure	Value type
54	time accuracy at 68.3% significance level	LE68.3 or LE68.3(r)	Quantity
55	time accuracy at 50% significance level	LE50 or LE50(r)	Quantity
56	time accuracy at 90% significance level	LE90 or LE90(r)	Quantity
57	time accuracy at 95% significance level	LE95 or LE95(r)	Quantity
58	time accuracy at 99% significance level	LE99 or LE99(r)	Quantity
59	time accuracy at 99.8% significance level	LE99.8 or LE99.8(r)	Quantity

Definitions:

54. Half length of the interval defined by an upper and a lower limit, in which the true value for the time instance lies with probability 68.3%.
55. Half length of the interval defined by an upper and a lower limit, in which the true value for the time instance lies with probability 50%.
56. Half length of the interval defined by an upper and a lower limit, in which the true value for the time instance lies with probability 90%.
57. Half length of the interval defined by an upper and a lower limit, in which the true value for the time instance lies with probability 95%.
58. Half length of the interval defined by an upper and a lower limit, in which the true value for the time instance lies with probability 99%.
59. Half length of the interval defined by an upper and a lower limit, in which the true value for the time instance lies with probability 99.8%.
