In English, null means nothing, nil, empty or void. In computing, null is a special value for nothing, an empty value. In geography, null tends to be what you get when you’ve been unable to geocode a place or an address and haven’t checked the geocoder’s response. What you end up with is a pair of coordinates of 0 degrees longitude and 0 degrees latitude, a point somewhere in the middle of the Atlantic Ocean, south of Ghana and west of Gabon. It’s here that you’ll also find Null Island, if you look hard enough.

I like maps. Even if you’ve never read posts on this site, the name “Mostly Maps” should probably be a giveaway. What you may not know is that I don’t really like musicals. Now granted I’ve seen Rent and Spamalot, but that’s because Alison and I were in New York and the former was recommended by one of my best friends and for the latter I’m a massive Python fan. Maps and musicals aren’t something that go together. But that may be about to change.
It’s easy to get stuck in a mental rut, to think that everyone thinks and feels the same way you do about a subject. But sometimes you need to get away and visit another country and another culture to find out that maybe there’s more than one way of looking at a subject. For me that subject is, unsurprisingly, maps and the other country was India.
Running between Edgware, Mill Hill East and High Barnet to the North of London to Morden to the South, the London Underground’s Northern Line stretches for 36 miles and takes in 50 stations. The line, marked in black on the Tube map, is a familiar sight to London commuters. But is the map of the line accurate? Does it reflect reality?
Up until the 6th. Century BC, it was commonly held that the world we live on was flat. Then Pythagorus came along and started to prove that the world is in fact a sphere. We now know that he was almost right and our planet is really an oblate spheroid, looking not dissimilar to a slightly squashed beach ball.
This may be a personal foible but when I join a new company I mentally set myself two targets. The first is what I want to achieve with that company. The second is how long it will take to achieve this. If you reach the first target then the second is a moot point. But if the first target doesn’t get reached and your self allocated timescale is close to coming to an end, then it’s time to take stock.
In his book A Zebra Is The Piano Of The Animal Kingdom, Jarod Kintz wrote “when you’re a cartographer, having to make maps sort of comes with the territory”. He’s right. When your business is making maps you should be able to do just that. But what if you’re not a cartographer? What if you had to draw a map of the country you live in? From memory? What would that map look like?
The Wikipedia entry for George William Frederick of Hanover, better known as King George III of the United Kingdom of Great Britain and Ireland, is full of details but misses out one key aspect of his life. In addition to concurrently being King, Duke and prince-elect of Brunswick-Lüneburg he was also a map addict and avid map collector.
About 2 years ago I wrote about something I called mapping the might have been; things that were planned and made it onto a map but which never came about. Now it’s time for the opposite; maps of things that haven’t yet come to be but which probably will. It’s less mapping the might have been and more mapping the will be.
Today’s digital maps, both on the web, on our mobile phones and in our cars are almost ubiquitous. But they’re not without their problems. They need recharging, updating and most need some form of network connectivity and that’s even before you look at the potential privacy aspects of who’s watching your position. But now there’s the next generation of portable navigation system.
