LAUNCHING JUNE 2013 with:
• CHOROPLETH MAPS WITH AGRICULTURAL
CENSUS 2010 RESULTS
• INSPIRE SERVICES FOR STATISTICAL UNITS

4. Plans for the rest of the year 2013
GEOSTATISTICS PORTAL

• 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. FUNCTIONALITIES AND LAYOUT

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. 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

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

15. CARTOGRAPHIC
PRESENTATION METHODS

16. Cartographic presentation methods
GEOSTATISTICS PORTAL
16
• choropleth maps
• diagram maps
– circle
• proportional,
• structural,
• proportional & structural,
– bar
• proportional,
• structural,
• proportional & structural,
– complex

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. 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. User defined parameters for choropleth maps
