Ordnance Survey Ireland

Ireland’s National Mapping Agency

Tá fáilte romhat chuig suíomh idirlín agus siopa ar líne Shuirbhéireacht Ordanáis Éireann. Gníomhaireacht Léarscáilíochta Náisiúnta na hÉireann atá muid agus tá léarscáiliú á déanamh againn ar Éirinn ó 1824.

Welcome to the official website and online store of Ordnance Survey Ireland (OSi).

Ordnance Survey Ireland has evolved from the Ordnance Survey Office which was established in 1824, later becoming a state body under the Ordnance Survey Ireland Act 2001. Under this Act, Ordnance Survey Ireland continued its mainstream public service function of creating and maintaining the definitive mapping records of the State and also assumed the commercial function assigned to it under the Act of developing its commercial business and sales revenues.

The work of OSi is essential to the infrastructural development of Ireland. There is a growing recognition among decision makers that knowledge and understanding of location is a key component in effective decision making. To this end, OSi has designed and developed a standardised, authoritative digital referencing framework that enables the consistent referencing and integration of national data related to location. This framework, known as PRIME2, provides the means for GIS data users to accurately integrate and use multiple data sources to provide for better analysis and decision making, optimising resources and delivering efficiencies.

Tailte Éireann

In parallel with internal developments and improvements, OSi is preparing to merge with two sister organisations, the Valuation Office and the Property Registration of Ireland.

The three organisations together manage a comprehensive set of property and geospatial data. By combining all three in Tailte Éireann, it will optimise the benefits of land information for the continuing economic and social benefit of Ireland, provide citizens, businesses and policy makers with ease of access to and use of location information, including property and title information, property valuation data, maps and aerial imagery, as well as leading, developing and maintaining national spatial information infrastructures and supporting better land management.

The government decision of the 20th January 2015 approved the drafting of the Tailte Éireann Bill 2014, along the lines of the general scheme attached, and provided with a memorandum for government, proposed by the Department of Justice and Equality.

On 1st January 2018, ministerial orders transferred responsibility for the three organisations to the now Minister of Housing, Local Government and Heritage. The general scheme of the Tailte Eireann Bill 2020 intends to establish a fully integrated land, property and spatial information services and includes a number of broad changes to the governance arrangements of the previously proposed general scheme.

The new general scheme will merge the three bodies, establishing Tailte Éireann as a scheduled office, under the Public Service Management Act 1997, under the direction of a Board and a Chief Executive. The new office is expected to be in place for the 1st January 2023
