ISO19123

ISO 19123 is an international standard that defines a schema for describing the properties of features in geographic information. It provides a framework for representing and exchanging information about the quality of geographic data. The standard focuses on the characteristics of features and their attributes, and how these characteristics can be measured and represented. It addresses various aspects of data quality, including accuracy, completeness, consistency, and lineage. ISO 19123 specifies how to define the "schema" of geographic features, which includes the types of features, their attributes, and the valid values for those attributes. It also defines how to express the quality of these features and attributes using a set of quality elements. This standard is part of the ISO 19100 series of standards for geographic information and is intended to promote interoperability and consistent understanding of geographic data. It is particularly relevant for data producers and users who need to specify and evaluate the quality of the geographic information they are working with.
