National Townland and Historic Map Viewer

The National Townland and Historical Map Viewer is a new application from the Ordnance Survey of Ireland and I have to say I am mightily impressed with what I've seen so far.  Not only is it a much more straightforward way of finding townlands on old maps than wrestling with their basic GeoHive viewer, there is the added bonus of being able to compare 2 representations side by side with a clever slider function.

The sample illustration above shows the Historic 6" colour map on the left and a matched up modern map on the right.  This is a great way of being able to see how places that you are interested in e.g. farms or churches, may still exist in the same place, or may have been swallowed up by urban growth.  You can even access great aerial photos to compare to the old maps, which is invaluable in trying to decide where to stick the co-ordinate pin into the cartoon Bing map that is usually the only mapping function most of us have access to in our genealogical software.

I had to ask the OSI how to use the application via the Feedback option - you may be more intuitive than me.  I've written up their excellent clear advice on my Irish Maps and Gazetteers page and repeated it on my Townlands page for good measure.

I encourage you to have a play - there are some wonderful historic features you can have highlighted by choosing them from the layers list.  So, if gas works, gravel pits, sluices and windmills of the 1830's are your thing, this is how you'll find them!

Hi Eamon,
I'm not sure if you accidentally submitted your comment before you had finished writing it, but do get in touch again if you want some more help searching for townlands. You can use the contact form too if you have a specific question.

Hello, I saw on your townlands page (https://www.irish-geneaography.com/townlands.html) that the OSI map viewer link was outdated. I contacted OSI and received an updated link if you want it! https://osi.maps.arcgis.com/apps/webappviewer/index.html?id=bc56a1cf08844a2aa2609aa92e89497e

Bless you Amelia! Updating that link was on my to do list and you have really helped me out. I love using maps to solve place puzzles and this way of being able to compare old and new maps side-by-side is so useful.

Thanks so much for getting in touch.

    I'm Ruth and here are my own observations, good, bad and indifferent on all things geographically & genealogically Irish, and occasionally, Scottish.
