In January of this year I made a hopeful prediction that 2013 would be the year of the tangible map.

This hope was prompted by the maps I saw at one of London's geomob meetups in November of 2012, where I saw and, importantly for a tangible map, touched Anna Butler's London wall map and a prototype of David Overton's SplashMap.

The hopeful prediction was made as a result of literally getting my hands on one of Anna's London maps and it's a treasured possession, though still sadly needing a suitable frame before it can take pride of place on a wall at home.

But what of SplashMaps? In November 2012 the project was on Kickstarter and I was one of the investors in this most tangible of maps. In December 2012 Splashmaps met their funding targets and went into production and today, through the letterbox came my own, tangible, foldable, scrunchable and almost indestructible SplashMap of my local neighbourhood.

Back in February of this year, at the height of the madness that was the Vaguely Rude Places Map, Ed Freyfogle from London's #geomob meetup got in touch and asked me to come and tell the story behind the map. This is that story.

And so last night, in the Chadwick Lecture Theatre in the basement of London's UCL, after listening to some amazing presentations on building a map of mobile cell tower coverage, of building a seismically powered alternative to GPS and a whole host of other great talks, I took my place on the podium and started where any good story needs to start ... at the beginning.

In 1943 psychologist Abraham Maslow wrote a paper called A Theory Of Human Motivation which set out what he perceived as our basic needs, laid out in a hierarchy.

The growth and uptake of today's internet and web allows us to do a lot of things that were previously the preserve of the professional. You can see this in the rise of words which now have citizen prepended to them. We don't just write blog posts, we're citizen journalists. We don't just take photographs, we're citizen photographers. To this list, we can now add citizen cartographer as well.

With the help of OpenStreetMap, HERE's Map Creator (which I work on) and Google's Map Maker, anyone with a modern web browser and an internet connection can now help to make maps where previously there were none and to improve and keep maps up to date, which still remains one of the biggest challenges to map making.

There's already been a book about OpenStreetMap, which I wrote about in April of 2011. As far as I know, no-one's written about HERE's Map Creator but for Google's Map Maker there's Limoke Oscar's Instant Google Map Maker Starter.

If there's an unwritten law of digital map making it is this: given a data set with a geographical element, someone, somewhere, will probably make a map out of it.

A prime example of this law is mining data from Encyclopedia Metallum detailing the Heavy Metal bands per country and mashing it up with population data from the CIA World Factbook (yes, this really exists) to make a map of Heavy Metal bands, by country, per capita.

Each time I find a new map I always end up learning something, sometimes directly from the map, sometimes from the content of what the map is trying to show. But I always end up learning something. In the case of this map, from H. W. Hill and Co from Decatur, Illinois circa 1884, I learnt that ...

• That you really can put pigs on a map.
• That in the 1880s each US state (apparently) had a nickname for a pig. Or is it that the States have nicknames that are best represented by pigs? Or maybe something else entirely.
• What a hog ringer is. Apparently it's a device for putting rings in the noses of pigs. Ouch.

Yesterday, Google launched their Maps Engine Lite beta; a way of quickly and easily visualising small scale geographic data sets on (unsurprisingly) a Google map. The service allows you to upload a CSV file containing geographic information and style the resulting map with the data added to it. I thought I'd give it a try.

I turned to my tried and trusted data set for things like this; a data set I derived from a Flickr set of geotagged photos I'd taken of the London Elephant Parade in 2010. It's a known data source and I know what the results of this data set will give me; it lets me do a reasonably meaningful visual comparison of how a particular product or service interprets and displays the data.

This is another mass transit map, but this time it's not of the London Underground system, but the U-Bahn and S-Bahn system in Berlin. The name U-Bahn derives from Untergrundbahn, or underground railway whilst S-Bahn comes from Stadtschnellbahn, or fast city train.

As a general rule of thumb, the London Underground is, as the name suggests, underground in the centre of the city and surfaces as you move into the suburbs. The same can't be said of the U-Bahn and S-Bahn, which is underground and overground in pretty much equal measures over a lot of the network.

But this post is not about the official map of Berlin's transport, it's about this, unofficial, map of Berlin's underground and not so underground trains.
