P 11.1Use data from National Spatial Data Infrastructures Use authoritative and INSPIRE compliant geospatial data and servicesAny geospatial information used to geospatially enable or display statistical or other data (location information and/or reference data for geocoding), or to produce statistical content, should preferably be built on agreed, authoritative and INSPIRE compliant geospatial data and services.
P 11.1Use data from National Spatial Data Infrastructures Implement unique identifiers and lifecycle informationFollowing INSPIRE and UN-GGIM: Europe Core Data specifications, the use of unique and persistent identifiers and lifecycle information is recommended, in order to describe the temporal characteristics of a version of a spatial object (or the changes between versions). Use of unique and persistent identifiers and lifecycle information will help to effectively keep track of changes in time and space, thus facilitating integration of geospatial and statistical information.
P 11.1Use data from National Spatial Data Infrastructures Define roles and responsibilities of organisations involved in production of geospatial informationThe different roles and responsibilities of various organisations involved in production of geospatial information should be well defined through formal protocols, agreements and Memorandum of Understanding (MoU). For instance, it should be agreed who maintains what information and how often data are updated. Custodian and stewardship models may need to be established to identify the most relevant stakeholders for a geospatial data source. MoU contributes to broaden the scope of geospatial and statistical integration within the design and production of statistical indicators and geospatial statistics, and also provides a context for modernisation and harmonisation of concepts and methodologies, bearing in mind the need to meet quality standards.
P 11.1Use data from National Spatial Data Infrastructures Establish common geospatial reference data repositories within NSDIsThe NSDIs must establish a reference data repository building on relevant, authoritative geospatial data and services, and promote the use of open data, in order to help both public and private actors to support their statistical and geospatial processes, including survey procedures.
P 11.1Use data from National Spatial Data Infrastructures Include Big Data in NSDIsThough being in an early stage of development, countries should be open to and consider the need to include geospatial Big Data in their NSDIs and its potential. A common infrastructure for Big Data needs to be adapted concerning its features such as volume and velocity. If the spatial features and smart captors (e.g., sensor data and mobile/streaming data) are themselves elements that move over time, this may mean that the geographic reference frames must be scalable over suitable temporal frequencies, which could go as far as continuous updates (real-time basis). Earth Observation Data should be considered as a valuable Big Data source through its analytical potential on spatial resolution and time series encouraging its integration in official statistics (e.g., land use and land cover monitoring statistics) and management with authoritative and more traditional data sources and processes.
P 11.2Use point-based reference data for geocodingUse point-based geospatial reference data for geocodingUse of point-based geospatial reference data should be adopted as the main and preferred approach for geocoding in the ESS. It is also recommended for non-European countries. In the absence, and only in the absence, of point-based reference data, more general location descriptions and/or larger geographies (e.g., enumeration areas or other statistical geographies) should be used.
P 11.2Use point-based reference data for geocodingProvide authoritative point-based geospatial reference data for geocodingRepositories of point-based geospatial reference data, needed for geocoding of statistical or other information, should be provided through the NSDI in all Member States. Priority should be given to the reference data listed as Core data by UN-GGIM: Europe (e.g., Address, Building and Cadastral parcel), which refer to INSPIRE Themes. Data need to be accurate and consistent, have sufficient coverage and meet internationally and nationally agreed standards.
P 11.2Use point-based reference data for geocodingSet up national standards-based address registersAll countries should set up a single geospatially enabled, national and authoritative address register based on national and/or international standards. As minimum, the address register should be available for public institutions to include in their respective business processes, but the address register should preferably be open data.
P 11.2Use point-based reference data for geocodingProvide open geocoding servicesGeospatial agencies should provide geocoding services based on national and authoritative reference data building on agreed standards (e.g., OGC geocoding API). Access to geocoding services should preferably be open.
P 11.3Build formal working relationships on institutional agreements Share knowledge and experience across communities at national level NSIs and geospatial agencies should work actively to increase mutual exchange of knowledge between the geospatial and statistical communities by occasional and/or continuous training, information, communication and/or by working on concrete cooperative projects. Cooperation should be overseen and monitored by regular national steering groups composed of senior experts from both communities.
