This document defines the structure and content of a text string implementation of the abstract model

for coordinate reference systems described in ISO 19111:2018. The string defines frequently needed

types of coordinate reference systems and coordinate operations in a self-contained form that is easily

readable by machines and by humans. The essence is its simplicity; as a consequence there are some

constraints upon the more open content allowed in ISO 19111. To retain simplicity in the well-known

text (WKT) description of coordinate reference systems and coordinate operations, the scope of this

document excludes parameter grouping and pass-through coordinate operations. The text string

provides a means for humans and machines to correctly and unambiguously interpret and utilise a

coordinate reference system definition with look-ups or cross references only to define coordinate

operation mathematics. A WKT string is not suitable for the storage of definitions of coordinate

reference systems or coordinate operations because it omits metadata about the source of the data and

may omit metadata about the applicability of the information.

This International Standard

— is a profile of ISO 19157:2013 Geographic information — Data quality;

— establishes a set of data quality elements and measures for describing the quality of address data;

— describes procedures for reporting data quality;

— provides guidelines for the use of the established set of data quality elements and measures for describing the quality of address data.

This International Standard is applicable to those evaluating and reporting the quality of address data such as address data managers, address data aggregators, and address data users.

This International Standard does not attempt to define minimum acceptable levels of quality for address data.

This document specifies the data structure and content of an interface that permits communication between position-providing device(s) and position-using device(s) enabling the position-using device(s) to obtain and unambiguously interpret position information and determine, based on a measure of the degree of reliability, whether the resulting position information meets the requirements of the intended use.

A standardized interface for positioning will allow the integration of reliable position information obtained from non-specific positioning technologies and will be useful in various location-focused information applications, such as surveying, navigation, intelligent transportation systems (ITS), and location-based services (LBS).
