The real map of Ireland

​​​​Founded in 1845, Geological Survey Ireland is the Republic of Ireland's public earth science knowledge centre.

We are a division of the Department of Communications, Climate Action and Environment.

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. 

Geological Survey Ireland also provides a Duty Geologist service to the public to address geological queries and concerns, please email duty.geologist@gsi.ie
