The following are examples of maps of differing scale. Use this composite to compare scales (pdf) guide and then click on the required example or go directly to the examples listed below:
1:1000 (approx. 55" to 1 mile) (pdf): mapping at 1:1000 began at the end of the 1960s for Dublin, Cork, Galway, Limerick and Waterford cities. This has extended over the years and this scale is now available for urban areas with a population in excess of 1,500 (approx). Revisions are now running at about every 1-2 years.
1:2500 (25" to 1 mile) (pdf): this scale comprises maps from both the older 25" series and the newer 1:2500 series. The old 25" series covers all areas of the country except for remote rural regions. For more information about the old 25" series see Trinity Map Library's description. The newer 1:2500 series covers suburban and peri-urban areas and is revised approximately every 3 years. The OSI characteristics sheet provides a guide to symbols used on these maps.
1:5000 (approx. 12" to 1 mile): mapping at this scale covers rural areas and will be updated approximately every 5 years.
1:10,560/1:10,000} (6" to 1 mile) (pdf): maps at this scale are available for the whole of Ireland but have not been updated since the 1930s. For more information about this series see the TCD guide on 6" maps (pdf). The OSI characteristics sheet provides a guide to symbols used on these maps.
1:50,000 (pdf) Discovery Series. Richview Library has complete sets of these series.
