Geological Survey Ireland

Founded in 1845, Geological Survey Ireland is Ireland's public earth science knowledge centre and is a division of the Department of the Environment, Climate and Communications.

We are committed to providing free, open and accurate data and maps on Ireland's subsurface to landowners, the public, industry, and all other stakeholders, within Ireland and internationally. 

In addition, we act as a project partner in interpreting data and developing models and viewers to allow people to understand underground. 

We deal with a diverse array of topics including bedrock, groundwater, seabed mapping, natural disasters, and public health risks.
