From paper maps to point based statistics
- 1. From paper maps to point based statistics Mirosław Migacz Chief GIS Specialist Central Statistical Office of Poland m.migacz@stat.gov.pl INSPIRE Geospatial World Forum Conference Lisbon, May 27th 2015
- 4. What we had (2009) BUILDING THE GIS 4
- 5. Spatial data collected by official statistics BUILDING THE GIS Statistical address points • address points for dwelling locations (only) Statistical division borders • Statistical regions • Census areas 5
- 6. Reference materials BUILDING THE GIS • Ortophotomap, • Cadastral Data, • Administrative division borders, Primary: • LPIS (Land Parcel Identification System), • Road and street network (commercial), • Geographical Names. • Topographic Data Base. Secondary: 6
- 7. Address point acquisition – pilot project BUILDING THE GIS 4 municipalities selected for the Trial Agricultural Census 2010 statistical division boundaries and address point acquisition reference material quality assessment assessment of time needed for a nationwide operation 7
- 8. Address point acquisition – pilot project BUILDING THE GIS scanning and calibration of statistical maps digitization of statistical division borders (statistical regions and census areas) automatic address point extraction from cadastral data manual address point acquisition (with situation sketches as primary reference) 8
- 9. Work schedule (nationwide) BUILDING THE GIS • reference material collection January 2009 – December 2009 • reference material processing January 2010 – May 2010 • address point acquisition January 2010 – June 2010 • address point database update continuously since July 2010 9
- 10. Results BUILDING THE GIS 210 GIS operators in 63 regional offices 6 months time (January – June 2010) 5,7 milion statistical address points acquired 10
- 11. CENSUS UPDATE OF ADDRESS POINTS
- 12. Agricultural Census 2010 CENSUS UPDATE OF ADDRESS POINTS 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 36 12
- 13. Agricultural Census 2010 webservice for municipalities CENSUS UPDATE OF ADDRESS POINTS 13
- 14. Population and Housing Census 2011 CENSUS UPDATE OF ADDRESS POINTS update in municipalities (January 2011 – 3 weeks) • internet map service • on-line editing • printouts still available visual survey by enumerators (March 2011 – 3 weeks) • results imported to statistical address point databases 14
- 15. Population and Housing Census 2011 webservice for municipalities CENSUS UPDATE OF ADDRESS POINTS 15
- 16. Results CENSUS UPDATE OF ADDRESS POINTS 16 The only set of address points in Poland that: • is complete, • has been verified in the field, Created and maintained within official statistics
- 17. GIS IN CENSUSES
- 18. Census applications GIS IN CENSUSES 18 Dispatcher Dispatcher application Enumerator Mobile application supervision
- 19. Dispatcher application Enumerator supervision • task assigment • address points • interviews • trail monitoring • support Census completeness monitoring GIS IN CENSUSES 19
- 20. Dispatcher application – table view GIS IN CENSUSES 20
- 21. Dispatcher application – map view GIS IN CENSUSES 21
- 22. Mobile 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 GIS IN CENSUSES 22
- 23. Mobile application GIS IN CENSUSES 23
- 24. Mobile application – map module GIS IN CENSUSES 24
- 27. GEOSTATISTICS PORTAL 27 What’sitfor? •statistical data geovisualization •spatial data publishing •network services (INSPIRE)
- 28. Statistical data publishing – data sources Census results • Agricultural Census 2010 • Population and Housing Census 2011 Local Data Bank • statistical data of a broad scope that are available down to municipality (LAU2) level • data for years: 2009-2013 Eurostat grants • GEOSTAT project • Merging statistics and geospatial information GEOSTATISTICS PORTAL
- 29. Statistical data publishing – cartographic presentation methods GEOSTATISTICS PORTAL 29 • choropleth maps • diagram maps – circle • proportional, • structural, • proportional & structural, – bar • proportional, • structural, • proportional & structural, – complex
- 32. Publishing statistical data on grids GEOSTATISTICS PORTAL 32 GEOSTAT project Merging statistical data and geospatial information
- 33. Publishing statistical data on grids - classifications GEOSTATISTICS PORTAL 33 Total population Population by: • sex • 0-14, 15-64, 65+ age groups Femininity ratio More to come…
- 34. Network services – INSPIRE GEOSTATISTICS PORTAL Central Statistical Office of Poland is the authority responsible for two annex III spatial data themes: statistical units SU population distribution (demography) PD 34
- 35. INSPIRE services in the Geostatistics Portal • discovery service – running, • view service: – statistical units – running, – population distribution (demography) – running, • download service: – statistical units – running, compliant with the data specification (GML), – population distribution (demography) – running, compliant with the data specification (GML), • metadata – published for existing data sets and services. GEOSTATISTICS PORTAL
- 36. INSPIRE services - datasets GEOSTATISTICS PORTAL 36 Statistical Units (SU) • Statistical regions and census enumeration areas (BREC) [2010-2014] • Territorial division units for statistical purposes (NTS) [2010-2014] Population Distribution (demography) (PD) • Total population in statistical regions and census enumeration areas (BREC) [2011] • Total population and population classifications by sex and three (0- 14, 15-64, 65+) age groups in territorial division units for statistical purposes (NTS) [2011-2012] All datasets are available publically and free of charge
- 37. INSPIRE Thematic Clusters GEOSTATISTICS PORTAL 37 • On-line collaboration platform for: – sharing experiences, – asking questions, – solving problems regarding INSPIRE implementation of: https://themes.jrc.ec.europa.eu/
- 38. NEW DEVELOPMENTS
- 39. Geostatistics Portal – Phase II GEOSTATISTICS PORTAL Project started May 22nd 2015 Spatial address databases • revision of our point based statistics framework Geostatistics Portal • new functionalities INSPIRE • new datasets and services
- 40. Spatial address databases GEOSTATISTICS PORTAL To make it easier to maintain our point base statistics framework: • Software update • ArcGIS 9.3.1 -> ArcGIS 10.3 • Reference data distribution automation • Operational data reporting and backup automation • Minor improvements in the dedicated application
- 41. Geostatistics Portal GEOSTATISTICS PORTAL advanced spatial analysis on microdata Local Data Bank – full scope on-the-fly visualizationof user-supplied data mobile application other minor improvements
- 42. Advanced spatial analysis on microdata all census results collected with reference to an address point spatial analysis possible in any desired area available for users within official statistics
- 43. Local Data Bank – full scope a huge database with lots of historical statistical data most data available for years 2003-2014
- 44. Visualization of user-supplied data
- 46. Other improvements upgrade of the website’s CMS • W3C Web Content Accessibility Guidelines upgrade of the usage monitoring system • hit counters for specific webpages, modules, services • INSPIRE services monitoring tools for administrators • user management upgrade • language version manager
- 47. New INSPIRE services • statistical gridsSU • population data on gridsPD
- 48. Geostatistics Portal – summary access to a huge amount of data: • census results, • Local Data Bank a variety of cartography presentation methods INSPIRE compliant services Exciting new developments GEOSTATISTICS PORTAL 48
- 49. Other geospatial activities of Polish official statistics European Forum for Geography and Statistics • Ongoing cooperation with other EU countries to create and promote georeferenced statistics Development of guidelines for point based statistics EU framework • GEOSTAT2 project – Eurostat grant with wide EU participation, coordinated by Sweden Merging statistics and geospatial information Eurostat grants • Spatial statistics related to infrastructure, transport and education • Statistical linked open data GEOSTATISTICS PORTAL 49
