Merging statistical data and geospatial information in Member States
At the end of 2012, the CSO joined the project entitled "Merging statistical data and geospatial information in Member States".As part of the project in the Programming and Coordination of Statistical Surveys Department (CSO), inter alia, an analysis of the possibilities of demographic data visualization in a different division of space than the currently used administrative units was carried out. Methodology of presenting data on population distribution using cadastral division, statistical division and a kilometre grid was developed and analysed. For this purpose, during the project a number of geospatial analyses were conducted with the use of data collected during the National Census of Population and Housing 2011 and additionally obtained spatial data (geodetic precincts, statistical regions and census enumeration areas). It was possible to carry out these analyses due to the fact that for the needs of censuses the official statistics created a spatial database of address points representing the location of residential buildings in Poland.Using the data acquired under the project an additional database of address points representing the location of enterprises was created. Using the data acquired under the project an additional database of address points representing the location of enterprises was created.
The Centre for Urban Statistics of the Statistical Office in Poznań developed a methodology for a commuting survey with the use of the data acquired in the National Census of Population and Housing 2011. The results of the survey were used in the works under the project, and their purpose was to show the effects of linking geo-information and statistical information.
In addition, the Regional and Environmental Surveys Department (CSO) conducted an analysis on the possible use of collected spatial data for creating statistical indicators for spatial planning, and it developed methodology for calculating building and road density ratios. The aim of this task was to assess the possibility of using geospatial data from administrative sources for regional analyses.

In January 2015, the Central Statistical Office (CSO) started the implementation of the second project from a series of grants called "Merging statistical data and geospatial information in Member States".
The implementation of three sub-projects was planned within the framework of the Project:
- „The degree of utilization of school places and teaching conditions in primary schools in the Mazowieckie voivodship in 2014 and in the 2020 perspective”;
- „Communication access of the selected urban centres in correlation with the analysis of the economic entities distribution”;
- „The methodology of assessing the suitability of spatial sets possible to use in the visualisation of statistical data based on the example of selected housing phenomena”;
The aim of sub-project 1 was to develop a research methodology and to illustrate the degree of utilization of places in primary schools in 2014 and in 2020, taking into account the demographic situation using an example of the selected voivodship (Mazowieckie). Moreover, the conditions of teaching in primary school were examined by showing the diversity of the number of pupils per one teacher in an institution. Statistical regions displaying the excess and shortage of places in primary schools were marked in relation to the number of school-age children domiciled in a given statistical region and the diversity of the teaching conditions in primary schools were presented.
The aim of sub-project 2 was to develop a methodology of conducting research in the field of the multimodal communication accessibility of the selected centres of economic activity and the distribution of economic entities with respect to some elements of the infrastructure on the example of the Kujawsko-Pomorskie and Podlaskie voivodships.
The aim of sub-project 3 was to develop a methodology of assessing the suitability of the Topographic Objects Database (BDOT) to visualise statistical data and to determine the suitability of BDOT to pursue goals of public statistics in spatial terms, using the example of the coverage of a selected voivodship.
It was a 24-month project, which ended 1t January, 2017 r.
Employees from the following entities were involved in the project:
- The Central Statistical Office – from the Programming and Coordination of Statistical Surveys Department, Regional and Environmental Surveys Department, Demographic and Labour Market Surveys Department;
- Statistical Offices in Białystok, Bydgoszcz, Olsztyn and Warsaw.
See the report on the work carried out under this project:
The implementation of a two-year grant on Development of guidelines for publishing statistical data as "linked open data" was started in January 2016. It is another grant from a series of grant projects called "Merging statistics and geospatial information in Member States".
The general goal of the project is to support the decision-making processes involving the delivery of a standardised, affordable and open form of spatially referenced statistical data. The Polish official statistics contains a huge amount of statistical data distributed across various databases and made available using different methods of publication. Providing access to the resources of statistical data in the form of Linked Open Data would be highly beneficial to customers.
The achievement of the project goal will be possible through an inventory of the collections and databases existing in statistics and their detailed analysis in terms of content, georeference and the degree of „openness”. The next step will be to develop a strategy for the publication of the statistical data resources as Linked Open Data including the following specific objectives:
- defining territorial units of the subdivision of the country for which data may be published along with an inventory of their spatial representation for each year,
- standardising identifiers of territorial units of the subdivision of the country which are the link between statistical information and space,
- analysing publication possibilities concerning the current resources of statistical data in the form of open data,
- identifying steps necessary to transform the current statistical data resources into open formats,
- describing the statistical resources using metadata in the RDF standard (Resource Description Framework),
- analysing the possibilities of publication of open data in the Geostatistics Portal, including the development of principles of web application for open data.
The project involves employees of:
- The Central Statistical Office: the Programming and Coordination of Statistical Surveys Department, Information Department, Analyses and Comprehensive Studies Department,
- Statistical Offices in Olsztyn, Poznan and Wroclaw (the Local Data Bank Centre in Jelenia Góra).
