Abstract
The INSPIRE directive regulates the provision of existing spatial information according to 34 data themes to support European environmental policies. Common implementing rules and technical guidelines are adopted to ensure that the national SDIs are compatible and usable in a European and cross-border context. A number of INSPIRE data themes is considered topographic reference data that is usually collected and maintained by National Mapping and Cadastral Authorities (NMCAs). EuroGeographics, the association of European National Mapping, Cadastre and Land Registry Authorities, and its members are working together to further the development of the European Spatial Data Infrastructure through collaboration e.g. in the ELF project. The ELF project is supported by a consortium of 30 partners across Europe, including NMCAs, industry and research. The goal of the project is to deliver the European Location Framework (ELF) - the technical infrastructure - which delivers authoritative, interoperable geospatial reference data from all over Europe. The ELF data specifications describe the conceptual data model for creating harmonised cross-border, cross-theme and cross-resolution pan-European reference data from national contributions. Thus, the ELF Data Specifications are an important cornerstone to ensure a coordinated approach regarding harmonisation of the NMCA’s data and services in matters of content, geometric resolution and quality. When adopted by data providers the ELF provides INSPIRE compliant data for Europe. The paper presents the chosen approach to create an NMCA profile for INSPIRE. Further, the challenges in the technical implementation of the ELF/INSPIRE data model are discussed. Finally, topics for future development regarding the maintenance of the specification structure are pointed out.
