– what we had
– what we wanted
– how we got it

4. BUILDING THE GIS
What we had (2009)

5. BUILDING THE GIS
Spatial data collected by official statistics
Statistical address points
• address points for dwelling
locations (only)
Statistical division
borders
• Statistical regions
• Census areas
5

6. BUILDING THE GIS
Reference materials
Primary:
• Ortophotomap,
• Cadastral Data,
• Administrative
division borders,
Secondary:
• LPIS (Land Parcel
Identification
System),
• Road and street
network
(commercial),
• Geographical Names.
• Topographic Data
Base.

7. BUILDING THE GIS
Software
ArcGIS 9.3.1
• ArcInfo

Geodatabases
• personal
• file

8. BUILDING THE GIS
Address 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. BUILDING THE GIS
Address 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. BUILDING THE GIS
Reference 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. BUILDING THE GIS
Work 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

12. BUILDING THE GIS

210 GIS operators in 63 regional offices
6 months time (January – June 2010)
5,7 milion statistical address points acquired

27. GEOSTATISTICS PORTAL

28. GEOSTATISTICS PORTAL
Geostatistics Portal
GEO.STAT.GOV.PL
LAUNCH: MARCH 2013
28

29. GEOSTATISTICS PORTAL
Geostatistics Portal functionalities
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
29

30. GEOSTATISTICS PORTAL
Geovisualisation 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 Housing
Census 2011 County (LAU1)
• Census data collected with spatial
reference to:
Municipality (LAU2)
• dwelling location
30

31. GEOSTATISTICS PORTAL
Census 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. GEOSTATISTICS PORTAL
Cartographic presentation methods
• choropleth maps
• diagram maps
– circle
• proportional,
• structural,
• proportional & structural,
– bar
• proportional,
• structural,
• proportional & structural,
– complex
32

33. GEOSTATISTICS PORTAL
Diagram 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. GEOSTATISTICS PORTAL
Choropleth 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.

47. GEOSTATISTICS PORTAL
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
