European Location Framework infrastructure
The DRDSI portal can use as its base map a European INSPIRE web service provided by the official sources, the National Mapping and Cadastral Authorities, through the European Location Framework. The ELF provides harmonized reference geospatial data across Europe (EU countries and more) through the cloud based open-source OSKARI and proprietary service platforms. The European Location Framework simplifies the use of INSPIRE compliant data in many ways delivering cross border content.
The EuroGeographics EuroGlobalMap and EuroRegionalMap provide topographic data which is geometrically and semantically consistent, at 1:1 million (45 countries) and 1:250,00 (33 countries) respectively. Users of the DRDSI portal can connect to up to continuously updated information from the ELF browse the map, visualizing other information in a consistent location or make queries of location attributes, or process spatial analysis of all the content. In this way we can already select, for instance, a section of the topographic map of Europe at 1:250,000 scale covering the whole Danube region area and combine it with other information.
Users can get more information about the features and process network analysis of for example a river network seamlessly, across state boundaries, because all features from national sources are edge-matched assuring no gaps or overlaps exist at the state borders.
The data in ELF can be overlaid with other available national or international data sources, for example the geological information from OneGeology-Europe and combine these with population and health statistics and so on. In the map view you can see the 1:1 million EuroGlobalMap and 1:250,000 EuroRegionalMap data on top of the mosaic satellite data from the Copernicus services.
The ELF will also provide access to far more detailed official national data, for example for administrative units, addresses and even large scale cadastral parcels. Although not yet available for all of the Danube Region it is already available in, for example, Czech Republic and Norway. Through the cadastral parcel authorized users will have access to ownership, land use and other important information.
The ELF infrastructure is still under development, the first implementation phase runs for 3 years ending in March 2016 and represents a 13 million euro investment in a reference data infrastructure. Importantly the European Location Framework will be established as sustainable solution for users and application developers offering an efficient and standardized access to pan-European reference and thematic data from official sources.
