Requesting Free OSI Maps for Your Research
What Maps and Data are Available to Request?
Would you like to use a map in your classwork, essay, research project or thesis?
Maps can both enhance your work and enlighten your reader. A map can help you present research findings visually on a map, add a new dimension to your work, make your essay more accessible or appealing for the reader or show information in a different way.
Historical maps can help explain a story or event and bring a former era to life. You can apply for historical maps in either PDF or TIFF format.
Ordnance Survey Ireland has produced a variety of historical maps from 6inch to 1 mile maps dating from the 1840s to 25inch maps dating from the early 20th century. You can find links to the historical PDF maps which are available on this page:
Some of the historical mapping series area available as raster data (in TIFF format) you can find information about applying for this data here:
libguides.ucd.ie/findingmaps/freeOSimapdata look in the section named HISTORICAL RASTER DATA IN TIFF FORMAT
With aerial imagery you can view changes in the landscape and see the layout of towns or villages from above. The aerial imagery is ortho-rectified which means distortions caused by camera tilt and topographical features are removed in order to produce a scale accurate image.
The aerial mapping is available in colour from either 2005 or 2011-2013. You can find links to sample PDF aerial maps as well as the application form on this page:
This is available for the whole country whether the area is urban or rural. Data is supplied in a DWG format and can be used in software such as AutoCad or ArcGIS. The OSi explains more about vector data on this website page.

To apply for large scale vector data see the section VECTOR DATA on libguides.ucd.ie/findingmaps/freeOSimapdata
On this page you can look at samples and get the link to the application form.
Current maps are maps which have been created / surveyed within the past 6 to 24 months.
They can be requested in PDF format ranging from A4 size up to A0 size. There are various options to choose from - large scale maps at 1:1000 1:2500 or 1:5000 scale, and Discovery series maps at 1:50,000 scale.

What to do if the PDF map won't open
The map files are in PDF X/1-A format and cannot be edited. The PDF map will not open if software that has the ability to edit PDFs is installed.
Therefore, the files need to be opened in a standard PDF Reader.
The most common PDF Reader software comes from Adobe. OSI suggest that a package available from Foxit will also work.
This is the link to the Adobe Reader:
