The OSi/CSO open data collaboration illustrates the application of a modern
concept known as linked data. By linking population statistics and geospatial
data, colour coded maps can be generated ‘on the fly’ to show the results of
almost any desired search.
The full lessons along with a supporting toolkit are available in three different formats,
A4, A3 and as a Powerpoint deck.

toolkit, including teachers’ notes.
In this lesson we deal with the way digital technology is being used to link different types of data in order to assist decision making. For example, assume that a computer manufacturer is looking for a suitable location in Ireland for a new manufacturing unit. The organisation will need to be confident that it can recruit graduates to fill a variety of roles at the new site. Accordingly, the planner involved decides to identify those locations in Ireland with an output of third level graduates. How would the planner find the information needed? Not long ago this would have been a time-consuming task.
Now however, such information is very easy to access and visualise. This is due to an innovative collaboration between Ordnance Survey Ireland (OSi) and the Central Statistics Office (CSO). The planner can also be sure that the information provided is accurate and reliable. In other words the data is authoritative data.
What is authoritative data?
Authoritative data is data that is offi cially recognised as being valid and correct. The availability of such data avoids the risk of using faulty information to support a potentially costly exercise such as a major business plan or regional development plan. An organisation that provides the authoritative information is known as an Authoritative Data Source.
Both OSi and the CSO are authoritative sources. OSi is the source of geographical data (also known as geospatial data or spatial data). The CSO Is the recognised source of information relating to
economic, social and other activities.
The collaboration of these two organisations provides a source that allows the planner to find and combine maps with the appropriate social data. This source is called the Census 2016 Open Data Site and can be accessed at http://census2016.geohive.ie/.
The data provided by the site is open data. This means that the information can be accessed, used or redistributed by anyone free of charge. The OSi/CSO open data collaboration illustrates the application of a modern concept known as linked data.

Science and Technology in Action (STA) is designed to support the teaching and learning of science and related subjects.
Each annual edition of STA contains a set of lessons that are industry led to be used by all teachers in second level schools. These lessons are available on this website and can be downloaded in a pdf format along with their supporting materials.
A hard copy is usually sent out for free to all second level schools each school year.
Science and Technology in Action (STA) is proudly supported and partnered by some of Ireland’s leading organisations and is produced in close cooperation with the support services of the Department of Education and Skills and the Irish Science Teachers Association (ISTA).
