Authoritative geospatial data is one of the basic building blocks for digital transformation and can be defined by seven characteristics that foster its trust across borders and between users, says a new report.
Researchers and practitioners in national mapping, cadastres and land registries (NMCAs) asked EuroGeographics, EuroSDR and KU Leuven what they believe makes their geospatial data authoritative. By identifying common characteristics, the aim was to gain a better and more comprehensive understanding of the definition, nature, governance and future of authoritative data and the links to spatial data quality in Europe. The research found that agreed rules of creation and use, a legal aspect, accountability, quality management, certification, traceability, and maintenance, were all recurring themes.
Report co-author Mick Cory, Secretary General and Executive Director of EuroGeographics which represents European NMCAs said: “Our members are recognised as the official sources of national geospatial information and whilst their data is routinely described as authoritative, it was not fully clear how the term is applied and interpreted across Europe.”
“Official, authoritative data is important because it supports a range of legal, fiscal, security and other public administrative purposes. For example, cadastral authorities and land registries fulfil an essential role providing official, detailed, secure and reliable information on property rights and registration.”
