GEOSTATISTICS PORTAL

GEO.STAT.GOV.PL LAUNCHING JUNE 2013 with:
• CHOROPLETH MAPS WITH AGRICULTURAL CENSUS 2010 RESULTS
• INSPIRE SERVICES FOR STATISTICAL UNITS
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)
FUNCTIONALITIES AND LAYOUT
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
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

CARTOGRAPHIC PRESENTATION METHODS
Cartographic presentation methods
GEOSTATISTICS PORTAL
16
• choropleth maps • diagram maps
– circle • proportional, • structural, • proportional & structural,
– bar • proportional, • structural, • proportional & structural,
– complex
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.
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.
User defined parameters for choropleth maps

INSPIRE SERVICES
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
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
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
Discovery Service
• metadata search engine in the Geostatistics Portal
• discovery service running – compliant with OGC CSW 2.0.2. specification
GEOSTATISTICS PORTAL
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
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.

SUMMARY
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
