In Praise of Paper Maps

Old maps of London

When was the last time you held a paper map? I don’t just mean a map printed on paper, I mean one that was designed to be viewed on paper in the first place. The London A to Z would count, so would those in a printed atlas or obtained from a tourist office to navigate an unfamiliar city. Of the hundreds of maps I see each year, I would guess that less than 10% have been designed for printing. This to me is a great shame for a few reasons. Firstly, paper is just better in many circumstances. It is by far the most reliable means of storing navigation information: it doesn’t need batteries or an internet connection (you could say the maps are pre-cached) and you can drop it in a puddle and it will still work. It also offers a nice sized and efficient visual interface- street corners seem to be increasingly populated with those squinting into their phone. If you spot someone with an A-Z they tend to have a quick look at the map and then start looking around to get their bearings.

One of my favourites: “Bacon’s Picture Map of London” from 1908

The impact of a larger visual interface is further enhanced by the fact that a paper map offers something much more tangible. You can hold it (and smell it if it is old and musty), lean over it, write on it and fold it whatever way you wish. In the context of data visualisation, paper maps offer something much more engaging, with people tending to look and think about them for much longer than their on-screen counterparts. 18 months or so ago I produced both online and printed versions of a surname map for London. Each visitor to the online version has spent on average less than a minute (according to Google Analytics) looking at it, whilst my fairly unscientific observations from lurking at the backs of various rooms where the map has been displayed suggest that people spent two or three times that looking at the paper version (even though the online version actually contains 15 maps). If I had to guess who found the map most memorable I bet it would be the people who saw the paper version. It is for these reasons that community mapping projects often use printed maps rather than electronic equivalents to engage with those they are working with.

The final thing I would say in praise of paper maps is the fact they make the cartographer work much harder. Paper does not enable easy zooming so labels and symbols need to be clear and uncluttered and the use of colour (or black and white) becomes even more important. Every map I have produced for print has required some kind of manual input from me to shift a few labels around or re-position features. In these cases I have to think about the interpretability of the map much more and frequently spot errors that would go unnoticed if I was making the map in an automated way. People appreciate these changes, which is why the likes of David Ismus’ map of North America has proved so popular. I just hope that they don’t go overlooked as electronic maps become more prevalent and people begin to view maps as simple “infographics” portraying a single headline dataset or relationship.

That said, I know that digital maps are better for many things too (not least easy dissemination) and so this is not meant to be some kind of nostalgic technophobic rant. Many of the maps I produce look much better on screen and, frankly, I wouldn’t have this blog without recent advances in mapping technology and an abundance of data to showcase it. It just strikes me that paper is still better for many things and so we shouldn’t be afraid to use it, even if (or precisely because) it requires a little more thought to get our message across.

  1. We recently scanned in a set of old maps, though not that old — circa 1943. They show New York City at the citywide, borough, and neighborhood level for a document called the “NYC Market Analysis”. The document is an impressive compendium of Census data from the time, plus vintage photos, local narratives, and the maps — showing block-by-block rent levels from the early 1940s.

    At the risk of plugging our own project, I wanted to comment on your post because it struck a cord about our work with the 1940s NYC maps. The printed maps, especially when they’re bound in the document and you can (carefully) flip through them and see them next to the photos, are really incredible. But in addition to the maps being artfully prepared, the tangible feeling you get from holding them in your hand I think adds to their beauty — it gives you a modest sense of awe as you handle maps from 70 years ago. And that is certainly magnified if you’re working with maps that are even older.

    I was thrilled we were able to scan the maps and make them available online — now many many more people can appreciate them. But the online version loses some of the power of the printed set.

    I’ve written about this and other aspects of the project here http://spatialityblog.com/2012/06/04/welcome-to-1940s-new-york/ The maps themselves are here http://www.1940snewyork.com

  2. I’m a geographer in my 40s and computer literate, but refuse to have a smartphone, IPad etc – it is just more screen time. Digital maps mean you have to be using some type of computer and, yes, those break or malfunction as well. Therefore paper maps rule in our household. Also all the cartography I commission for articles and chapters at work is esentially designed for print. It has to be that way – most journals don’t take anything else that something you can pront out – videos and moveable screen images like on here are a step too far for the likes of the Transactions. Our geog dept. still has maps everywhere. I think people will be commuting to work looking at maps in a book or a printed newspaper for some time to come. For driving, opinions are split. My generation detest looking at Google Maps while going along on a smartphone, if we even had one, might just about use a Satnav, and always carry an actual map.
