The Property Registration Authority (PRA) is the State organisation responsible for the registration of property transactions in Ireland. The PRAs Digital Mapping Project ran from September 2005 to September 2010. This was a major transformation project involving the digitisation of approximately 2.4 million land parcels, made up of approximately 15 million line segments. The Project is complete, with 99.9% of land parcels successfully digitally mapped with issues resolved. As can be expected, some residual and historical issues, which existed in the paper-based pre-digital system, came to light during the process. The vast bulk of such issues were dealt with and any outstanding issues are resolved on an ongoing basis. Such unresolved issues represent only 0.1% of the overall number of registered land parcels.
