1INSPIRE Data, metadata and tools A proposalAgainst the background of the seven hypotheses presented in this document, the European Forum for Geostatistics (EFGS), under a generous grant from EUROSTAT, have from the beginning of this year started work on the GEOSTAT ESSnet project. The project consortium of nine NSI’s is led by Statistics Norway. The need to take action for the integration of geography and statistics should not be limited to the European scale.We therefore propose:The establishment of a Global Forum For Geostatistics (GFGS) to serve as a professional reference group (PRG) for Geostatistics and provide a professional link between UN and the NSI’s in issues related to this field.. This PRG will primarily be concerned with questions related to the integration of geography (GSDI projects) and statistics (GEOSTAT)The initiation of a joint UN spatial data infrastructure (SDI) project for geostatistics. This is the first step towards a GSDI based Global Integrated Information System (GGIISS) and should be developed in close cooperation with the national mapping agency (NMA) -led GSDI and INSPIRE projects.The initiation of the GEOSTAT GSSgrid project to provide a high-resolution harmonised infrastructure for geostatistics liberated from administrative areas and demonstrating its power and utility through a UN project to plot the global population on km grids.Keywords: GSDI (Global Spatial Data Infrastructure), GSS (Global Statistical System), Small area statistics, GIS (Geographical Information System), GGIISS (Global Geographic Integrated Information Systems of Systems)Mr Ekkehard PetriGIS project manager for Geoportals and the GEOSTAT projectEurostat, European CommissionUnit E4, Regional Statistics and GIBECH A3/031 L-2920 LUXEMBOURGTel:ESTP course on Geographic Information Systems (GIS):Use of GIS for making statistics in a production environmentStatistics Norway, Oslo, 26th to 30th of March 2012Attribution (by) Licensees may copy, distribute, display and perform the work and make derivative works based on it only if they give the author or licensor the credits in the manner specified by these.

4What is INSPIRE? INfrastructure for SPatial InfoRmation in Europe A framework directive of the European Parliament and of the Council of 14 March 2007 (Directive 2007/2/EC) on the establishment of such a Spatial Data Infrastructure (SDI)
5INSPIRE is about improving access to spatial information: The environment doesn’t stop at bordersDistributed infrastructure: INSPIRE is to be based on the infrastructures for spatial information established and operated by the Member StatesOrganisational and technical harmonisationData held by or on behalf of public authorities (including Statistical Offices)Data falling under the themes listed in the DirectiveFor Community environmental policies and policies or activities which may have an impact on the environment.
11A little INSPIRE history 2007 Adoption of INSPIRE directive2008 First implementing rule on Metadata2009 – 2013 Further Implementing RulesSince 2007 Transposition into national lawSince 2011 INSPIRE geoportalUntil 2020 Implementation phase in Member States
12INSPIRE principlesData should be collected once and maintained at the level where this can be done most effectivelyIt should be possible to combine seamless spatial information from different sources across Europe and share it between many users and applicationIt should be easy to discover which geographic information is available and under which conditions it can be acquired and usedGeographic data should become easy to understand and interpret
13INSPIRE non-principles No requirement to create new spatial informationNo obligation to provide data for freeNo minimum level of quality
14INSPIRE Legislation INSPIRE Directive – a framework directive Transposition into national legislationDetailed technical definition in Implementing Rules (Regulations)Implementing rules on Metadata, Network Services, Interoperability, Monitoring and Reporting and Data SharingIn addition non binding Technical Guidance documents
15Scope of INSPIRE Metadata Content: fixed list of elements Format: to treat it automatically (catalogues, search engines)Data specifications: data from different sources is comparableAnnex I, Annex II, Annex III (3 lists of spatial data themes)Network services (machine to machine communication)Discover service: to be able to find the data in distributed cataloguesView service: to evaluate the data visuallyDownload service: to actually get the dataTransformation service: coordinate transformationInvoke service
16Scope of INSPIRE – spatial information MetadataSpatial data setsSpatial data services
21Metadata Metadata are data about data We distinguish between structural metadata and descriptive metadataSDMX for statistics covers bothINSPIRE metadata for spatial data are descriptive metadataMetadata serve different purposes (data discovery, assessing fitness for use, data access, data transfer, use)INSPIRE metadata are for discovery, some elements on access and fitness for useWithin the publish-find-bind pattern of a service oriented archtitecture MD are essentialMetadata for data users (find) and for data producers (publish)
22Metadata for spatial information EN ISO standards for metadata on spatial data (ISO ) and on spatial services (ISO )Lists almost 300 possible metadata elementsMD elements can be mandatory, optional or conditionalContain a core profile mainly for use in catalogue servicesISO core the starting point for INSPIRE metadataFor specific communities profiles are recommended (selection of metadata elements in addtion to
23Metadata for spatial information Metadata are structured in packages
24Metadata are usually encoded in XML (ISO standard 19139)
25INSPIRE metadataINSPIRE metadata are regulated in „COMMISSION REGULATION (EC) No 1205/2008 of 3 December 2008 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards metadata”Contains in total 21 metadata elements (19 for data sets and 17 for spatial data services)Further implementation details in INSPIRE Metadata Implementing Rules: Technical Guidelines based on EN ISO and EN ISO (Version 1.2)
26Obligations in Member States regarding Metadata 03-Dec-2010 Metadata available for spatial data sets and services corresponding to Annex I and II09-Nov-2011 Discovery and view services operational03-Dec-2013 Metadata available for spatial data sets and services corresponding to Annex III
29Problems with metadata Nobody likes to create metadataStructure well defined, content notSemantic interoperability not enforcedUnclear titlesEmpty abstracts or other fields
30Tools for metadata work Metadata editorMetadata validator
31ExerciseCreate Metadata on NUTS 2006Download the exercise sheet from the EFGS website
32Recommendations Rather write too much than too little. Make the title speak for the full dataset.Begin the abstract with a short summary paragraph which is often shown in a geoportal.Put into the abstract information on the main attributes, the data sources and references to legal acts.Some information could be redundant (geographic coverage, dates) but help the userIn the lineage field carefully document the way the data have been produced.

35Data models and transformations The INSPIRE data specifications prescribe a specific data structure.This should help users to immediately understand the dataINSPIRE does not require the creation of new data -> Transformation of data into the INSPIRE format will be common practice.
39Search for dataINSPIRE queryables in the Metadata – e.g. title, abstract, resource type, keywords, topic categoryThematic search and spatial search
40Tour of the INSPIRE geoportal Exercise I: Search for all datasets on Hydrography with English metadata in LuxembourgExercise II: Add 2 View services from the same area on top of each other and change the transparency of the top one.
