ISO 19157-1:2023

Geographic information - Data quality - Part 1: General requirements

This document establishes the principles for describing the quality of geographic data. It:

—    defines a well-considered system of components for describing data quality;

—    defines the process for defining additional, domain-specific components for describing data quality;

—    specifies components and the content structure of data quality measures;

—    describes general procedures for evaluating the quality of geographic data;

—    establishes principles for reporting data quality.

This document is applicable to data producers providing quality information to describe and assess how well a dataset conforms to its product specification and to data users attempting to determine whether or not specific geographic data are of sufficient quality for their particular application.

This document does not attempt to define minimum acceptable levels of quality for geographic data. Such information is usually present as a requirement in a data product specification, defined in accordance with ISO 19131, for example.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
