Data Quality Policy and Submission form

Ordnance Survey Ireland (OSI) is the national mapping agency of Ireland. It is the State Agency responsible for the official, definitive surveying and topographic mapping of the Republic of Ireland. As this mapping is topographic, it only represents the physical features on the ground at the time of survey.

OSI maps never indicate legal property boundaries, nor do they show ownership of physical features. Although some property boundaries may be coincident with surveyed map features, no assumptions should be made in these instances and consequently it is not possible to identify the position of a legal property boundary from an OSI map.

OSI welcomes all customer feedback about the content and accuracy of our mapping. There can be a delay between changes taking place on the ground and when we are able to capture them within our continuous mapping revision programme. Any issues relating to the content or accuracy of our mapping that fall within our specification will normally be investigated at the earliest possible opportunity.

The Data Quality Policy submission form below must be completed and submitted before your query can be dealt with.
