I've recently been guilty of using the term map wallpaper as a mild form of pejorative; meaning maps that are great for showing geographical context but which don't really show anything else. I'm also guilty of overusing the phrase eye candy; something which is eye catching but ultimately superficial.

Then along comes an eye candy map wallpaper app for my MacBook Pro and all pejoratives are instantly replaced with superlatives. Yes, this is eye candy. Yes, this is map wallpaper. But in this case the geographical context is spot on and it's definitely eye catching without being superficial in any way.

The moment you make a map there's a fairly good chance that it will be out of date. There's nothing wrong with this; anyone who works in the cartography or mapping fields will tell you that one of the biggest challenges in making maps is not making the map, it's keeping it up to date once it's made. Geography is constantly moving, changing, flowing thing.

One of the most fascinating aspects of old maps is not so much looking at what's changed since they were made, though that is fascinating enough, but of what might have been but then never was.

Regular readers of this blog may have worked out that out of all the maps there are, my favourite is the London Underground Tube map. A browse through the London Tube Map Archive shows just how much the Tube network has expanded and contracted over the years and how stations have changed not only in name but sometimes in position as well. But some of these maps also show what was planned but which was never realised; as Trent Reznor once put it "all the what abouts, the might have and could have beens". Take a look at this map of the network from 1938.

First there was neogeography, a convenient label for the practice of geography outside of the formally accepted geographical disciplines. A convenient label, but one which caused some controversy and mud slinging with the aforementioned formally accepted disciplines being labelled paleogeography and with a strong emphasis on the pejorative.

So it seems almost inevitable that we now have a proposal from the International Cartographic Association to form a commission on neocartography, looking into the practise of making maps outside of the formally accepted cartography profession.

Just like RSS, the death of the map has been widely predicted, but to paraphrase Mark Twain, the death of both have been greatly exaggerated. Produce an online data set with some form of geospatial or location content and someone, somewhere, will produce a map of it.

Sometimes the resultant map leaves a lot to be desired, such as the recent UK government's attempts to map crime across the country. But sometimes, the map shows something much more interesting, topical and relevent, such as the use of social media in the recent events in Egypt.

Hypercities have produced a series of maps "for traveling back in time to explore the historical layers of city spaces in an interactive, hypermedia environment" and have now produced a map showing the Tweet stream during and after the stepping down of Egyptian government.

A quick review through last year's posts shows a fairly consistent theme of mine; that despite the absence of the map in many of today's location services sometimes the map is the best way of simply presenting information in a readily accessible and understandable form.

But a map is much more than just a visualisation for overlaying data upon, a map says as much about the fears, hopes, dreams and prejudices of its target audience as it does about the relationship of places on the surface of the Earth.
