Available Digital Data

The Geological Survey of Ireland has a range of digital data available, free of charge.

IWDDS
Gridded xyz data, ESRI GIS shapefiles, Geotiffs, reports and metadata are available to view, clip and export from the Interactive Web Data Delivery System.

DCENR download page

GIS Data is available to download in pre-zipped folders from the Department of Communications, Energy and Natural Resources' spatial data download page. The data is in the format of ESRI GIS shapefiles.

Viewers

Various viewers have been created for different GSI projects. See the table below or online mapping.

The table below outlines the GSI datasets that are available, the format that they are available in and from which source.
