@UML(identifier="DQ_QuantitativeAttributeAccuracy", specification=ISO_19157) public interface QuantitativeAttributeAccuracy extends ThematicAccuracy
Accuracy of quantitative attributes.

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
68 attribute value uncertainty at 68.3% significance level LE68.3 or LE68.3(r) Quantity
69 attribute value uncertainty at 50% significance level LE50 or LE50(r) Quantity
70 attribute value uncertainty at 90% significance level LE90 or LE90(r) Quantity
71 attribute value uncertainty at 95% significance level LE95 or LE95(r) Quantity
72 attribute value uncertainty at 99% significance level LE99 or LE99(r) Quantity
73 attribute value uncertainty at 99.8% significance level LE99.8 or LE99.8(r) Quantity

Definitions:

  1. Half length of the interval defined by an upper and a lower limit, in which the true value lies with probability 68.3%.
  2. Half length of the interval defined by an upper and a lower limit, in which the true value lies with probability 50%.
  3. Half length of the interval defined by an upper and a lower limit, in which the true value lies with probability 90%.
  4. Half length of the interval defined by an upper and a lower limit, in which the true value lies with probability 95%.
  5. Half length of the interval defined by an upper and a lower limit, in which the true value lies with probability 99%.
  6. Half length of the interval defined by an upper and a lower limit, in which the true value lies with probability 99.8%.
