GIS in Polish Official Statistics - from paper maps to Geostatistics Portal

  1. 1. GIS in Polish Official StatisticsFrom paper maps to Geostatistics Portal Mirosław Migacz Chief GIS Specialist Central Statistical Office of Poland m.migacz@stat.gov.pl EUROGI imaGIne Opportunities Everywhere Conference Dublin, March 7th 2013
  2. 2. AGENDA• Building the GIS – what we had – what we wanted – how we got it• Census update of address points – update in municipalities – visual survey• GIS in censuses – dispatcher application – mobile application• Geostatistics Portal 2
  3. 3. BUILDING THE GIS
  4. 4. BUILDING THE GISWhat we had (2009) 4
  5. 5. BUILDING THE GISSpatial data collected by official statistics Statistical address points • address points for dwelling locations (only) Statistical division borders • Statistical regions • Census areas 5
  6. 6. BUILDING THE GISReference materials Primary: • Ortophotomap, • Cadastral Data, • Administrative division borders, Secondary: • LPIS (Land Parcel Identification System), • Road and street network (commercial), • Geographical Names. • Topographic Data Base. 6
  7. 7. BUILDING THE GISSoftwareArcGIS 9.3.1• ArcInfo• ArcEditor• ArcViewGeodatabases• personal• file 7
  8. 8. BUILDING THE GISAddress point acquisition – pilot project 4 municipalities selected for the Trial Agricultural Census 2010 statistical division borders and address point acquisition reference material quality assessment assessment of time needed for a nationwide operation 8
  9. 9. BUILDING THE GISAddress point acquisition – pilot project scanning digitization automatic manual and of statistical address point address point calibration division extraction acquisition of statistical borders from cadastral (with maps (statistical data situation regions and sketches census areas) as primary reference) 9
  10. 10. BUILDING THE GISReference materials quality assessment Situation sketches • available for the whole of Poland • compliant with the statistical dwelling register • last updated in the field in 2002 (inconsistencies with actual terrain situation) Cadastral data • allows automatic extraction of address data • deficient data source (not available for some territories at the time) • maintained at county level – lots of different approaches to the data distribution standard • coordinate reference system problems (local projections) 10
  11. 11. BUILDING THE GISWork schedule (nationwide) January 2010 – continuously• reference May 2010 • address point since July 2010 material • reference acquisition • address point collection material database processing update January 2009 – January 2010 – December 2009 June 2010 11
  12. 12. BUILDING THE GIS Results210 GIS operators in 63 regional offices 6 months time (January – June 2010) 5,7 milion statistical address points acquired 12
  13. 13. CENSUS UPDATEOF ADDRESS POINTS
  14. 14. CENSUS UPDATE OF ADDRESS POINTSAgricultural Census 2010 36 update in municipalities (July 2010 – 3 weeks) • internet map service • modifications indicated on printouts • results sent to statistical offices to be manually entered into the databases visual survey by enumerators (August 2010 – 3 weeks) • results imported to statistical address point databases 14
  15. 15. CENSUS UPDATE OF ADDRESS POINTSAgricultural Census 2010webservice for municipalities 15
  16. 16. CENSUS UPDATE OF ADDRESS POINTSPopulation and Housing Census 2011update in municipalities(January 2011 – 3 weeks)• internet map service• on-line editing• printouts still availablevisual survey by enumerators(March 2011 – 3 weeks)• results imported to statistical address point databases 16
  17. 17. CENSUS UPDATE OF ADDRESS POINTSPopulation and Housing Census 2011webservice for municipalities 17
  18. 18. CENSUS UPDATE OF ADDRESS POINTSResultsThe only setof address pointsin Poland that:• is complete,• has been verified in the field,Createdand maintainedwithin officialstatistics 18
  19. 19. GIS IN CENSUSES
  20. 20. GIS IN CENSUSESCensus applications Dispatcher Dispatcher application supervision Mobile Enumerator application 20
  21. 21. GIS IN CENSUSESDispatcher applicationEnumeratorsupervision• task assigment • address points • interviews• trail monitoring• supportCensus completenessmonitoring 21
  22. 22. GIS IN CENSUSESDispatcher application – table view 22
  23. 23. GIS IN CENSUSESDispatcher application – map view 23
  24. 24. GIS IN CENSUSESMobile application Smartphone • mobile app • VPN network Map module • GPS • orthoimagery • cadastral data • tasks Communication module • phone (to dispatcher only) • messaging • alarm procedure Census module • tasks • questionnaire 24

  26. 26. GIS IN CENSUSESMobile application – map module 26
  27. 27. GEOSTATISTICS PORTAL
  28. 28. GEOSTATISTICS PORTALGeostatistics Portal GEO.STAT.GOV.PL LAUNCH: MARCH 2013 28
  29. 29. GEOSTATISTICS PORTALGeostatistics Portal functionalitiesgeovisualization of census’ results • Agricultural Census 2010 • Population and Housing Census 2011publishing spatial data maintained within official statistics • statistical regions • census areaspublishing INSPIRE services for two annex III themes • statistical units • population distribution (demography)advanced spatial analyses on microdata • for authorised users within official statistics 29
  30. 30. GEOSTATISTICS PORTALGeovisualisation of census results Region (NUTS1)Agricultural Census 2010• Census data collected with spatial Voivodeship (NUTS2) reference to: • agricultural holding location • holder’s dwelling location Subregion (NUTS3)Population and HousingCensus 2011 County (LAU1)• Census data collected with spatial reference to: Municipality (LAU2) • dwelling location 30
  31. 31. GEOSTATISTICS PORTALCensus data storage and use• Geostatistics Portal database Region (NUTS1) stores census’ results aggregated to units of territorial division (down to LAU2) Voivodeship (NUTS2)• For each thematic phenomena absolute (non-standarized) values Subregion (NUTS3) are stored• Not all data stored in the Portal is County (LAU1) published for unauthorized users due to statistical data confidentiality issues Municipality (LAU2) 31
  32. 32. GEOSTATISTICS PORTALCartographic presentation methods • choropleth maps • diagram maps – circle • proportional, • structural, • proportional & structural, – bar • proportional, • structural, • proportional & structural, – complex 32
  33. 33. GEOSTATISTICS PORTALDiagram map A cartographic presentation method for visualisation of absolute data. Since absolute data are stored in the Geostatistics Portal database, they can be directly visualised on diagram maps. 33
  34. 34. GEOSTATISTICS PORTALChoropleth map A cartographic presentation method for visualisation of standarized data – statistical indicators. Geostatistics Portal stores a set of normalization attributes, which allow on-the-fly calculation of statistical indicators to be presented on choropleth maps. 34
  35. 35. GEOSTATISTICS PORTALUser defined parameters for choropleth maps THEMATIC PHENOMENA LIST STATISTICAL INDICATORS AGGREGATION LEVEL NUMBER OF CLASSES CLASSES CALCULATION METHODS COLOR SCALE TRANSPARENCY LABELS AND BORDERS VISIBILITY 35

  47. 47. GEOSTATISTICS PORTALGeostatistics Portal – benefits• access to a huge amount of data on agriculture and demography• a variety of cartography presentation methods• spatial analysis tools• INSPIRE compliant services• in the future: – geovisualization platform for results of surveys other than the census – geovisualization of data banks maintained by official statistics 47
