QUALITY MANAGEMENT OF REFERENCE GEO-INFORMATION

This paper will introduce how quality of geo-information can be managed when the production environment is no longer inside one organization (e.g. collection of data is contracted out) or data is compiled from various sources like in case of Spatial Data Infrastructures (SDIs). The bases for quality management of reference geo-information are discussed using three viewpoints; data, process and organization and user centric viewpoints. These viewpoints can be met using ISO 19157 and ISO 19158 standards together with ESDIN developed Quality Model and Data Quality Services Framework (DQSF). Two different services are identified a Data Quality Web Service and a Data User Web Service. We discuss how these principles and services are implemented now within EuroGeographics and Ordnance Survey of Great Britain. Further development will be done during the European Location Framework (ELF) project, which is providing a single source of reference geo-information for Europe during 2013-2016.
