Even an overwhelming vote margin can be interesting to map, but I’m a bit disappointed with the maps of the Irish referendum held last Friday on whether to repeal Ireland’s constitutional ban on abortion. The official Referendum Ireland website, the Irish Times and RTÉ News all use two-colour constituency map (one colour for yes, another for no); the Irish Times goes a little further and shows choropleth maps for the yes and no sides, but quartiles don’t reveal very much either. The Guardian and even Wikipedia show more granularity. [Maps Mania]
Richard Kirwan, a former director of Ordnance Survey Ireland, published a memoir in 2010 called If Maps Could Speak (Londubh). That memoir is now available in an ebook edition—or at least it is for the Kindle; I couldn’t find it in other ebook stores. [WMS]
Cóilín Parsons is the author of The Ordnance Survey and Modern Irish Literature (Oxford University Press, June 2016; Amazon, iBooks), which links the Ordnance Survey of Ireland to the origins of literary modernism in Ireland. Writing in The Irish Times, Parsons makes a larger argument about the cultural impact of the Irish survey, which resulted in large part from the survey’s precise mapping requirements and the need to hire non-cartographic scholars to get the job done—they were mapping aspects of Irish life that had not previously received official attention.
This unlikely assembly came about because the survey was instructed to make a map at a scale of six inches to one mile. The scale might seem unexceptional to anyone who grew up using the survey’s maps, but at the time it was nothing short of revolutionary—it called for enormous maps of frequently sparsely inhabited areas, and at a level of detail never before seen across such a vast expanse of land. How was the survey to gather the information to fill in such detailed maps? The answer was to task not only the engineers of the army, but also a crew of civilian workers under Petrie’s supervision, to both map the physical features of the landscape and also record every possible aspect of the landscape from its placenames (the initial justification for employing Irish language scholars) and archeology to its productive economy.
Rail Map Online is a web-based map showing every rail line that ever existed in the United Kingdom and Ireland. Base layers can be toggled between Google Maps, satellite, OpenStreetMap and old Ordnance Survey maps. It doesn’t distinguish between existing and removed rail lines, though that appears to be coming; it’s a work in progress. [Tim Dunn]
The European Space Agency has released this false-colour composite image of Ireland based on 16 radar scans by the Sentinel-1A satellite in May 2015. The colours show change over the 12 days of coverage: “The blues across the entire image represent strong changes in bodies of water or agricultural activities such as ploughing. […] Vegetated fields and forests appear in green. The reds and oranges represent unchanging features such as bare soil or possibly rocks that border the forests, as is clear on the left side of the image, along the tips of the island.” [ESA]
Another data point for our consideration of what people think a fantasy map looks like, from the author of the Maptitude tumblelog: a fantasy map of Ireland, replete with, as you would expect, forests and hills. It departs from the fantasy map paradigm by using colour: red for political boundaries, blue for water. It also uses a vaguely uncial script: something we’ve seen in the movie versions of The Lord of the Rings, but less often in fantasy book maps. Not inappropriate for Ireland, though.
