Mapping Our Future
RIA Lunchtime Lecture
To provide a national mapping service in the State… creating and maintaining the definitive national mapping and related geographic records
• to maintain and develop the underlying physical infrastructure which is needed to support mapping applications, including to maintain a national grid and the national geodetic and height frameworks and to link these to international systems,
• to create and maintain for the entire State mapping and related geographic databases which have national consistency of content, currency, style and manner including those areas which do not provide a commercial return on the activity,
• to provide mapping and related geographic information to the public and private sectors in support of social, economic, legislative, educational, security, business and administrative functions and requirements,
OSi Functions (1) – OSi Act 2001
19 November 2014
Mapping Our Future
RIA Lunchtime Lecture
• to encourage and promote the benefits of the use of the national mapping and related databases and the development of products, services and markets to meet national and user needs,
• to advise the Government, a Minister of the Government, a body established by or under statute and other public sector organisations on matters relating to the policy and practice of survey, mapping and geographic information and on the development of national spatial data infrastructures,
• to represent the State at international level on matters relating to mapping and geographic information,
• to provide the necessary technical support to the Chief Boundary Surveyor in the performance of his or her duties in delimiting statutory boundaries and the delineation of such boundaries on maps,
OSi Functions (2) – OSi Act 2001
19 November 2014

RIA Lunchtime Lecture
• to depict place-names and ancient features in the national mapping and related records and databases including the Irish language equivalent of place-names as advised by An Coimisiún Logainmneacha and declared in place-names orders made under section 2 of the Place-Names (Irish Forms) Act, 1973,
• to protect the Government copyright on OSI records, databases, products and published material including copyright on OSI records, databases, products and published material made prior to the establishment day.
