The INtegrated Mapping FOr the Sustainable Development of Ireland's MArine Resource (INFOMAR) programme is a joint venture between the Geological Survey of Ireland (GSI) and the Marine Institute (MI). The programme is the successor to the Irish National Seabed Survey (INSS) and concentrates on creating integrated mapping products related to the seabed.

In 2010 the boundaries were reshaped into more logical shapes as the initial shapes were merely indicative and drawn on large scale map of Ireland. They often did not cover all of the intended Bay or in the case of offshore areas, included extensive onshore areas. The reason for each new shape was recorded and documented. Admiralty Chart boundaries, SAC boundaries, Water Framework Directive waters and current survey coverage were used.

New Priority Areas as approved by the Board in April 2011. For the Priority Bays, we have excluded those areas where there are Priority Bays already to avoid needless duplication and overlap.

It is a vector dataset. Vector data portrays the world using points, lines and polygons (areas).

The data is shown as polygons. Each polygon holds information on name, ID and Area (km2).
