Geostatistics Portal - a platform for census data visualization

  1. 1. Geostatistics Portal A platform for census data visualization Mirosław Migacz Chief GIS Specialist Central Statistical Office of Poland m.migacz@stat.gov.pl www.linkedin.com/in/migacz INSPIRE Conference 2013: The Green Rennaisance Florence, June 26th 2013
  2. 2. • About the project • Functionalities and layout • Cartographic presentation methods • INSPIRE services 2 Agenda
  3. 3. GEOSTATISTICS PORTAL 3 GEO.STAT.GOV.PL LAUNCHING JUNE 2013 with: • CHOROPLETH MAPS WITH AGRICULTURAL CENSUS 2010 RESULTS • INSPIRE SERVICES FOR STATISTICAL UNITS
  4. 4. Plans for the rest of the year 2013 GEOSTATISTICS PORTAL 4 • diagram maps with Agricultural Census 2010 results • choropleth maps with Population and Housing Census 2011 resuts • diagram maps with Population and Housing Census 2011 resuts • INSPIRE services for Population Distribution (Demography)
  5. 5. FUNCTIONALITIES AND LAYOUT
  6. 6. Geostatistics Portal functionalities GEOSTATISTICS PORTAL 6 geovisualization of census’ results • Agricultural Census 2010 • Population and Housing Census 2011 publishing spatial data maintained within official statistics • statistical regions • census areas publishing INSPIRE services for two annex III themes • statistical units • population distribution (demography) advanced spatial analyses on microdata • for authorised users within official statistics
  7. 7. Geovisualisation of census results All statistical data georeferenced to a point Agricultural Census 2010 • Census data collected with spatial reference to: • agricultural holding location • holder’s dwelling location Population and Housing Census 2011 • Census data collected with spatial reference to: • dwelling location GEOSTATISTICS PORTAL 7 LOCATION Land Parcel Identification System Statistical address points
  8. 8. Census data storage and use GEOSTATISTICS PORTAL 8 Municipality (LAU2) County (LAU1) Subregion (NUTS3) Voivodeship (NUTS2) Region (NUTS1) • Geostatistics Portal database stores census’ results aggregated to units of territorial division (down to LAU2) • For each thematic phenomena absolute (non-standarized) values are stored • Not all data stored in the Portal is published for unauthorized users due to statistical data confidentiality issues
  9. 9. Default view GEOSTATISTICS PORTAL 9
  10. 10. Statistical division GEOSTATISTICS PORTAL 10
  11. 11. Object identification GEOSTATISTICS PORTAL 11
  12. 12. 12 Line based selection and buffering GEOSTATISTICS PORTAL
  13. 13. 13 Line based buffering GEOSTATISTICS PORTAL
  14. 14. 14 Polygon based buffering GEOSTATISTICS PORTAL
  15. 15. CARTOGRAPHIC PRESENTATION METHODS
  16. 16. Cartographic presentation methods GEOSTATISTICS PORTAL 16 • choropleth maps • diagram maps – circle • proportional, • structural, • proportional & structural, – bar • proportional, • structural, • proportional & structural, – complex
  17. 17. Diagram map GEOSTATISTICS PORTAL 17 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.
  18. 18. Choropleth map GEOSTATISTICS PORTAL 18 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.
  19. 19. User defined parameters for choropleth maps GEOSTATISTICS PORTAL 19 THEMATIC PHENOMENA LIST STATISTICAL INDICATORS AGGREGATION LEVEL NUMBER OF CLASSES CLASSES CALCULATION METHODS COLOR SCALE TRANSPARENCY LABELS AND BORDERS VISIBILITY
  20. 20. Choropleth map GEOSTATISTICS PORTAL 20 Percentage of holdings that keep 1 sow within all holdings in a voivodeship (NUTS2)
  21. 21. Diagram map (circle, proportional) GEOSTATISTICS PORTAL 21 Crop area in each subregion (NUTS3)
  22. 22. Diagram map (bar, proportional) GEOSTATISTICS PORTAL 22 Grain crops area in each subregion (NUTS3)
  23. 23. Diagram map (circle, structural) GEOSTATISTICS PORTAL 23 Structure of cultivation areas of 5 basic grains in each voivodeship (NUTS2)
  24. 24. Diagram map (circle, proportional & structural) GEOSTATISTICS PORTAL 24 Structure and combined area of root and fodder plants cultivation in voivodeships (NUTS2)
  25. 25. Diagram map (bar, structural) GEOSTATISTICS PORTAL 25 Structure and cultivation areas for various fodder crops in voivodeships (NUTS2)
  26. 26. Diagram map (bar, proportional & structural) GEOSTATISTICS PORTAL 26 Structure and combined value of seed crops in voivodeships (NUTS2)
  27. 27. Diagram map (complex) GEOSTATISTICS PORTAL 27 - Number of holdings with gardens - Number of holdings with plowed grounds - Number of holdings with permanent cultivation
  28. 28. Bar chart GEOSTATISTICS PORTAL 28
  29. 29. INSPIRE SERVICES
  30. 30. Spatial data themes 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 30
  31. 31. INSPIRE deadlines 3 XII 2013 • Discovery services • View services • Download services (datasets don’t have to be compliant with data specifications) • Metadata for data sets and services OCTOBER 2020 • Compliance with data specifications needs to be achieved GEOSTATISTICS PORTAL 31
  32. 32. INSPIRE services in the Geostatistics Portal • discovery service – running, • view service: – statistical units – running, – population distribution (demography) – 3rd quarter 2013, • download service: – statistical units – running, compliant with the data specification, – population distribution (demography) – 3rd quarter 2013, will be compliant with the data specification, • metadata – published for existing data sets and services. GEOSTATISTICS PORTAL
  33. 33. Discovery Service • metadata search engine in the Geostatistics Portal • discovery service running – compliant with OGC CSW 2.0.2. specification GEOSTATISTICS PORTAL
  34. 34. View Service – Statistical Units • view service running for statistical units – compliant with OGC WMS 1.3.0. specification, • object visualization compliant with the data specification, • a national statistical units style implemented (SU.VectorStatisticalUnits.Krajowy) GEOSTATISTICS PORTAL default style SU.VectorStatisticalUnits.Krajowy
  35. 35. Download Service – Statistical Units • download service for statistical units running as predefined dataset download service (compliant with Technical Guidance for the implementation of INSPIRE Download Services 3.0), • service is running on Atom 1.0 and OpenSearch 1.1., • statistical units data set divided into 16 GML files – one for each voivodeship, • data sets are compliant with the data specification for statistical units. http://geo.stat.gov.pl//atom_web-0.0.1/atom/JednostkiStatystyczne GEOSTATISTICS PORTAL
  36. 36. SUMMARY
  37. 37. Geostatistics 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 GEOSTATISTICS PORTAL 37
