OME 2 project reveals pan-European cadastral data strategy

The Open Maps For Europe 2 (OME2) project has revealed plans to boost the utilization of European cadastral data. This includes efforts to enhance its discoverability and accessibility.

As part of this endeavour, the project aims to develop a comprehensive pan-European Cadastral Data Strategy. This strategy will identify key stakeholders and outline the technological, procedural and resource requirements needed to support the long-term delivery of official high-value data. Specifically, it will focus on data related to addresses, cadastral parcels, buildings and administrative units.

The OME2 project is enhancing the Open Cadastral Map prototype, which is available through the Open Maps For Europe interface and currently provides large-scale coverage for six countries. The cadastral map comprises four layers: Administrative Units, Cadastral Parcels (and Cadastral Zones), Buildings (and Building Parts), and Addresses. It compiles and harmonizes INSPIRE open data to provide users with an overview of the information available, and user-friendly links for downloading it directly from the data providers’ national geoportals.

Ms Hara Papadaki is one of the team of experts from the Hellenic Cadastre who are working with the General Directorate on Cadastre Spain to develop this key project deliverable. She said: “Our vision is that the Open Cadastral Map becomes a single point to access pan-European high-value cadastral data enabling users to easily find authoritative information. To do this, we are developing common processes, guidelines and best practices, aligned to key European and global policies, for integrating data from national mapping, cadastral and land registration authorities.”

Establishing a smooth data process

“Whilst INSPIRE sets some common regulations which help to streamline existing data from those countries that comply with the directive, we have developed further specifications for our production process to achieve harmonization. This includes requirements for INSPIRE-endorsed gml schema, INSPIRE ATOM Feed Service for download, and ETRS 89 Coordinate Reference System. Our aim is to establish a process that delivers up-to-date, quality, authoritative cadastral data that is both easy to use and combine with other information.”

“For example, linking location with other datasets provides new insights and opportunities to inform decisions and operations, thus unlocking value and enabling more complex data transactions.”

Papadaki concluded by urging NMCAs to take advantage of the opportunity to promote the value of their expertise and information. She said: “Projects such as OME2 demonstrate our eagerness and competence to collaborate across sectors and national boundaries. By adjusting our operations and business models to reflect changes at international, as well as national and European level, we can be core agents in the implementation of important and high-profile initiatives, including the UN-endorsed Integrated Geospatial Information Framework (IGIF) and the open and high-value data.”

Plans for the pan-European Cadastral Data Strategy were presented at a recent workshop on Sustainable Business Models for NMCAs jointly organized by EuroSDR and EuroGeographics, which represents official national providers of geospatial information in Europe.

The OME2 project is co-funded by the European Union. It is being delivered by a consortium comprising: EuroGeographics, the not-for-profit membership association for Europe’s National Mapping, Cadastral and Land Registration Authorities; National Geographic Institute, Belgium; National Institute of Geographic and Forest Information, France; Hellenic Cadastre; General Directorate for the Cadastre, Spain; and Cadastre, Land Registry and Agency, the Netherlands. It runs until the end of 2025.
