Quick, take a look at this map. There’s something wrong with it. It’s a map of the coast of West Africa dating from 1839. Compared with modern maps, a few things have changed. Senegambia was the French controlled Senegal and the British controlled Gambia, Soudan is today’s Sudan and Upper Guinea is part of today’s […]

At the beginning of 2013 Google launched Google Maps Engine Lite, a simpler and easier to use version of their commercial Maps Engine, which was designed as a successor to Google’s My Maps feature. In essence, My Maps and GME were web based, simplified GIS tools, allowing a user to create maps with overlays of […]

Not all Geographic Information conferences are created equal. A great proof point for this is IRLOGI, the Irish Association for Geographic Information. Today I’ve been in Dublin at their annual GIS Ireland 2014 conference, which is in its 19th year. I’d been invited to give one of the opening keynotes; who could resist such an invitation?

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?
