  1. More and better Improvement of official statistics through the Swedish GeodataCooperation Jerker MOSTRÖM Senior Advisor, Regions and Environment Department, Statistics Sweden

  2. The Swed. GeodataCooperation • Launched in 2011 to fulfil the INSPIRE requirement on data sharing between public authorities • Statistics Sweden participated from start • The agreement is managed by the National Mapping and Cadastre Authority (Lantmäteriet) • Parties in the cooperation are authorities with an information responsibility and municipalities, government agencies and other organizations with official duties INSPIRE Conference Istanbul 2012

  3. The Swed. GeodataCooperation • The parties in the cooperation offer each other their spatial data for official use at an annual fee. • The INSPIRE regulation = minimum requirement, the Swedish GeodataCooperation has a broader scope • One agreement, one annual fee = access to more than 400geodata products

  4. Before 2011… …and after….. Geodata Cooperation Model 2011 One Joint agreement on public datasharing Public authorities: Geodata acquisition before 2011 (Example - data exchange and agreements) Organisation g Organisation a Organisation h Organisation b Organisation f Joint AgreementonDatasharing Organisation c Organisation e Organisation d Organisation d

  5. Geodata and geospatial applications at Statistics Sweden StatisticsSweden’sfirst population gridapplication 1988

  6. Geodata and geospatial applications at Statistics Sweden • Long tradition • GI integrated in production in twoways: • Creation of geospatial products (grids, localitiesetc) • Geospatial processing as part of the offcial statistics productionchain • Land use statistics mostgeodataintense • Some 20 productsconcerninguseof land and water, land ownership, urban green areas, designated areas, coastal and urban developmentetc

  7. More and better • Since 2011, moregeodatainvolved in the production process (all productsaffected) • Introductionof the Cadastralmap - moreaccuratearea estimations and new opportunities • Combination of register data and geodata is the keytoimprovement

  8. Some examples • Qualityimprovement: calculationof land and water area in Sweden • Qualityimprovement: calculationofbuilt-up land by combining administrative sourceswith the Cadastralmap • New statistics: buildingfootprint statistics using Real Property Register

  9. Land and water areas • Cadastralmapused for the firstime in 2012 • Some 4.2 million real propertyparcels aggregated tomunicipalities • Combinedwithwaterbodies • All data in scale 1:10 000 • Result: Land area ofSweden “shrinked” with some 3,000 square kilometres or 0.7 percent

  10. Built-up land • Part of the product ”Land Use in Sweden” • 8 categoriesofbuilt-up land • Somecategoriesreducedduetobettermethodology

  11. Before 2011 After 2011 Type: Industry Owner: Company Land area: 200.000 m2 Built-upland: 200.000 m2 – 78.000 m2= 122.000 m2 Type: Industry Owner: Company Land area: 200.000 m2 Built-up land: 200.000 m2? Register data Improvedfigure: 122.000 m2 X, Y Coordinates Geospatial data Land area: 200.000 m2 - Forested area: 78 000 m2

  12. Buildingfootprints 7.2 million buildings

  13. Masters Thesis: Potential for energyproduction from roofmounted solar panels

  14. Somechallenges • The more geospatial information used from external producers – the hardertocontrol data (quality, accuracy, coverage, definitions etc) • Metadata for ”mapproducts” – usually not fulfilrequirements for statistics production • Close dialoguewithproducersimportant. Get toknowthem and their data! • Technicalinfrastructure – Geospatial activitiesmoredemandingthan standard plattforms for statistics (hardware, software, storageetc).
