Norbert Rainer 64 th plenary session of the Conference of European Statisticians 28 April 2016, Paris CES Seminar 2016: Geospatial information services based on official statistics Key issues from the session II papers www.statistik.at We provide information Introduction Task is to present key issues of the 13 papers prepared for session II: Australia, Belarus, Germany, Italy, Lithuania, Mexico, Netherlands, New Zealand, Norway, Poland, Slovenia, USA and OECD Papers deal with manifold aspects of experience and practices in providing geospatial information services This presentation of key issues does not claim to be complete www.statistik.at slide 2 1
Overview of topics dealt Main topics dealt in the papers User needs Dissemination Georeference infrastructure Database and related aspects Geospatial Framework Partnership with NMCAs Keywords Changes and trends in user demand Geographical units, geoportals, interactive maps, webbased applications, visualisation, confidentiality Geocoding of addresses/location Geodatabase, GIS tools, metadata, methodological issues, preconditions National concepts, GSBPM, integration of geoinformation into the statistical process Basis and importance of cooperation with NMCAs and other relevant institutions, legal basis www.statistik.at slide 3 Geospatial information Statistics had always been elaborated and published on the basis of a regional context/geography Geoinformation of that geographical area was not of interest per se Integration of geoinformation into the statistical process increases the analytical value of the statistical information In achieving this, georeferencing of point-based units (e.g. address), definition of geographical/regional categories, development of databases, adaptations of the statistical processes, and new dissemination tools are needed www.statistik.at slide 4 2
Geospatial information Microdata of geospatial statistics as the result of the integration of statistical and geospatial information is geocoded (georeferenced) at - ideally - the location level Statistical data can then be disseminated at any desired level of geography (e.g. grids) Location based geospatial reference framework for statistical (and administrative) data sources, might be based on an address register or building and dwelling register Even without focus on the geoinformation that is integrated into the statistics, the need to produce small-area statistics necessitates the georeferencing approach www.statistik.at slide 5 www.statistik.at slide 6 3

User needs In general, customer demand is growing especially for social, economic and environmental information for small geographic areas to support evidence-based decision making Demand comes from all sectors: government, commercial, academia, citizens Increasing customer expectations and demand for visual presentation of data Modern communication technology, such as web applications Demanding simpler integration of data across the various data sources used in their analysis Focus on place/location based decisions (e.g. local area development, business location planning, infrastructure planning, liveability of places, environmental aspects) www.statistik.at slide 9 Dissemination issues Dissemination policy: open data, free of charge Confidentiality/disclosure avoidance Dissemination tools (geoportals, online atlas) Interactive web applications to retrieve thematic maps of statistical indicators for different geographic layers and time periods Interactive web applications that enable GIS analysis (e.g. circle around a certain point location of a certain radius, or free-hand areas) www.statistik.at slide 10 5

Summary of key issues Countries welcome the global and international initiatives, especially as concerns the development of concepts and standards (infrastructure for geospatial statistics) Standards help in producing geospatial data more efficiently and with required quality Papers provide in general good practices that could be exchanged All countries that provided papers are far or very far advanced in producing geoinformation services based on official statistics Countries do provide new or more adequate statistical data for evidence-based decision making at geographical levels www.statistik.at slide 23 Summary of key issues Need for developing geospatial information services is seen unanimously The benefits and added value of geospatial statistical data are undoubted The shift to location-based statistical data and the integration of geospatial and statistical information is viewed as a quite fundamental change in the statistical production process Thus, changes in data acquisition, statistical processes, technical infrastructure, human resources and skills are to be managed www.statistik.at slide 24 12
Summary of key issues Countries use geospatial data for survey purposes (esp. census) and for the delineation of functional areas Webbased interactive dissemination tools are in place in a lot of countries Because of its advantages statistical grids are widely used as geographical dissemination unit Increased risk of disclosure needs to be tackled Coping with increasing user demand is viewed as a big challenge Partnership with NMCAs is seen as crucial www.statistik.at slide 25 Everything that happens happens somewhere Source: Timothy Trainor, USA 13
Points for discussion Challenges from global and international geospatial initiatives User demand and value added of geoinformation services based on official statistics Requirements and good practices for partnerships between NSIs and NMCAs Challenges and good practices for the integration of geoinformation into the statistical process www.statistik.at slide 27 Please address queries to: Norbert Rainer Contact information: Guglgasse 13, 1110 Vienna phone: +43 (1) 71128-7703 fax: +43 (1) 71128 7053 norbert.rainer@statistik.gv.at Thank you for your attention! www.statistik.at slide 28 14
