BUILDING THE GIS

What we had (2009)

BUILDING THE GIS

4

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

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:

Address point acquisition – pilot project

BUILDING THE GIS

4 municipalities selectedfor 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

Address point acquisition – pilot project

BUILDING THE GIS

scanningand calibration

of statistical maps

digitizationof statistical

division borders

(statistical regions and

census areas)

automatic address point

extraction from cadastral data

manual address point

acquisition (with situation

sketchesas primary reference)

8

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

Results

BUILDING THE GIS

210 GIS operators in 63 regional offices

6 months time (January – June 2010)

5,7 milion statistical address points acquired

CENSUS UPDATEOF ADDRESS POINTS

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 intothe databases

visual survey by enumerators(August 2010 – 3 weeks)• results imported to statistical

address point databases

Agricultural Census 2010 webservice for municipalities


13

Population and Housing Census 2011


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

What’s it for?• statistical data

geovisualization• spatial data publishing• network services

(INSPIRE)

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


Statistical data publishing– cartographic presentation methods


29

• choropleth maps• diagram maps

Merging statistical data and geospatial information

Publishing statistical data on grids - classifications

Total population

Population by:• sex• 0-14, 15-64, 65+ age groups

Femininity ratio

More to come…

Network services – INSPIRE


Central Statistical Office of Polandis the authority responsible for two annex III spatial data themes:

statistical unitsSU

population distribution (demography)PD

34

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.


INSPIRE services - datasets


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

INSPIRE Thematic Clusters

NEW DEVELOPMENTS

Geostatistics Portal – Phase II


Project started May 22nd 2015

Spatial address databases• revision of our point based statistics framework

Geostatistics Portal• new functionalities

INSPIRE• new datasets and services

Spatial address databases


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

Geostatistics Portal


advanced spatial analysis on microdata

Local Data Bank – full scope

on-the-fly visualizationof user-supplied data

mobile application

other minor improvements

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

Local Data Bank – full scope

a huge database with lots of historical statistical data

most data availablefor years 2003-2014

Visualization of user-supplied data

Mobile application

iOS

Android

Windows Phone

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

New INSPIRE services
