INSPIRE and Open Data

Ireland’s Open Data Portal: The concept of Open Data is about making data held by public bodies available and easily accessible online for reuse and redistribution. As public bodies have progressed in areas like eGovernment and data analytics, the potential of data and, in particular, Open Data to help deliver economic, social and democratic benefits has become clearer. The portal brings these datasets together in a single searchable website. is intended to provide easy access to datasets that are free to use, reuse, and redistribute. The portal is operated by the Government Reform Unit of the Department of Public Expenditure and Reform.

Irish Spatial Data Exchange (ISDE): If Data is the New Currency then significant value can be gained from making existing data more available including promoting value-added reuse and eliminating duplication in data collection.  The Irish Spatial Data Exchange (ISDE) is a data discovery tool which allows you to find spatial data and services that are hosted across multiple government and academic organisations.

The Data Exchange has been developed by the Marine Institute with its partners the Geological Survey of Ireland, the EPA, the Department of Environment, Community and Local Government and the Coastal and Marine Research Centre (UCC) to make sharing data between organisations easier. Initial funding was from the Information Society Fund, the DCENR Change and Innovation Fund, the Marine Institute and the ISDE partners

The Data Exchange takes metadata feeds from ISDE partners and other Organisations which have contributed metadata to the DoECLG’s ISDI (Irish Spatial data Infrastructure) catalogue including:

  • All Island Research Observatory NUI Maynooth
  • Coastal and Marine Research Centre
  • Department of Agriculture, Food and the Marine
  • Department of the Arts, Heritage and Gaeltacht
  • Department of Environment, Community and Local Government
  • Environmental Protection Agency
  • Geological Survey of Ireland
  • Local Authorities
  • Marine Institute
  • National Transport Authority
  • Ordnance Survey Ireland
  • Petroleum Affairs Division
  • Property Registration Authority of Ireland

The information in the catalogue is based on the national ISDI metadata profile, which was developed by the ISDE partners and adopted by the ISDI WG as the national INSPIRE profile. The interface to the system is based on the OGC-standard CSW interface. The use of both of these standards allows for interoperability of catalogues and reuse by 3rd party applications.

ISDE was adopted by the ISDI WG and integrated into the EU INSPIRE portal as a first step towards meeting the targets of the INSPIRE directive. ISDE will continue to provide broad-based information on data availability for both INSPIRE and non-INSPIRE datasets which are relevant to Government bodies, research groups and the private sector.

DubLinked: Dublinked has been created to harness this rich resource of information, and to combine it with people who want to be innovative, to be creative, to think about new ways to do things in cities. Dublinked brings together the experts working at the coal-face, have them explain the challenges they are facing – whether it be in delivering water during a deep winter freeze or ensuring the traffic keeps flowing – and see if fresh eyes and innovative thinking can find new solutions. These are not solutions just for Dublin.

The Dublinked website contains a Datastore that allows the download of OpenData in Dublin and Ireland, a gallery of Apps that have been created using OpenData and a listings of upcoming activities.

Fingal Open Data: Fingal Open Data has been created by Fingal County Council to enable citizens to access data relating to Fingal. We will provide access to data from Fingal County Council and other public sector organisations that publish Fingal related data. Citizens are free to access and use this data as they wish, free of charge, in accordance with the PSI general licence. Use of any published data is subject to Data Protection legislation. Fingal Open Data was launched in November 2010 and is the first Open Data website in Ireland. We hope that following this initiative, other public sector bodies in Ireland will also release their data as Open Data.

GIS and Mapping Websites

All-Island Research Observatory (AIRO): The All Island Research Observatory is a research unit and interactive spatial data website based in the National University of Ireland, Maynooth. AIRO seeks to produce all-island, spatial datasets and specialist tools to aid their analysis and to undertake academic and applied mapping research. AIRO aims to act as a single point of access to a wide variety of spatial data and information about the various regions of Ireland. The intended audience of this site are planners, policy makers, researchers and those interested in gaining an understanding of the dynamics that are shaping the island of Ireland today.

AIRO provides access to hundreds of free to use mapping tools. Examples of such are as follows:

MyPlan: is a free and easy to use public information system about the development plan or local area plan in your local area. The aim of is to create a one stop shop for information about plans and also to provide other information which is relevant to planning decision-making (census, heritage sites, patterns of housing development etc). is an initiative of the Department of the Environment, Community and Local Government on behalf of each of the 88 planning authorities across the country. The local authorities will ensure that the information is kept up to date as possible.

The Department, with local authorities and other public bodies are working to ensure that, over time, expand to incorporate information about other aspects of the planning system such as information about planning applications and other planning matters being handled by local authorities and An Bord Pleanála.

Wind Atlas: The Sustainable Energy Authority of Ireland’s Wind Atlas is a digital map of Ireland’s wind energy resource. It provides detailed information on wind speeds, electricity transmission and distribution networks for specific locations around Ireland at national and county levels. Ireland has one of the greatest wind energy resources in Europe and it is important this is exploited to maximum advantage. The wind atlas can assist all those concerned with the wind planning process and be of great use to developers and policy makers alike. It is currently used by local authorities to help identify areas suitable for wind energy developments.

SEAI hopes to increase the usefulness of this atlas to a wider audience, helping to inform the public and educate our children about the nature and extent of Ireland’s wind energy resources.
