Geographic information - Data quality - Part 1: General requirements (ISO 19157-1:2023)

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.

Geoinformation - Datenqualität - Teil 1: Allgemeine Anforderungen (ISO 19157-1:2023)

Information géographique - Qualité des données - Partie 1: Exigences générales (ISO 19157-1:2023)

Le présent document établit les principes de description de la qualité des données géographiques. Il:
—    définit un système réfléchi de composants pour décrire la qualité des données;
—    établit le processus visant à définir des composants spécifiques à un domaine supplémentaires pour décrire la qualité des données;
—    spécifie les composants et la structure du contenu de mesures de la qualité des données;
—    décrit des procédures générales d’évaluation de la qualité des données géographiques;
—    établit les principes de rapportage de la qualité des données.
Le présent document s’applique aux producteurs de données fournissant des informations de qualité pour décrire et évaluer la façon dont un jeu de données répond à la spécification de contenu informationnel et aux utilisateurs cherchant à déterminer si des données géographiques spécifiques présentent ou non une qualité suffisante pour leur application particulière.
Le présent document n’a pas vocation à définir des niveaux minimums acceptables de qualité en matière de données géographiques. Ces informations sont généralement fournies sous forme d’exigences dans les spécifications de contenu informationnel, définies conformément à l’ISO 19131, par exemple.

Geografske informacije - Kakovost podatkov - 1. del: Splošne zahteve (ISO 19157-1:2023)

Ta dokument določa načela za opisovanje kakovosti geografskih informacij, in sicer:
–    opredeljuje dobro premišljen sistem elementov za opisovanje kakovosti informacij;
–    opredeljuje proces za določanje dodatnih elementov, specifičnih za posamezno področje, za opisovanje kakovosti informacij;
–    določa elemente in vsebinsko sestavo postopkov na področju kakovosti informacij;
–    opisuje splošne postopke za ocenjevanje kakovosti geografskih informacij;
–    vzpostavlja načela za poročanje o kakovosti informacij.
Ta dokument se uporablja za proizvajalce podatkov, ki zagotavljajo kakovostne informacije za opis in oceno stopnje ustreznosti nabora podatkov specifikaciji izdelka, ter uporabnike podatkov, ki poskušajo ugotoviti, ali so določene geografske informacije dovolj kakovostne za njihovo želeno uporabo.
Ta dokument ne poskuša določiti minimalnih sprejemljivih ravni kakovosti geografskih informacij. Te informacije so na primer običajno prisotne kot zahteva v specifikaciji za podatkovne izdelke, ki je opredeljena v skladu s standardom ISO 19131.
