Now you might think that you know the US.

But we're going to look at some maps that show it

in a completely different light, looking at some new data that

shows us how the US has built up over the last two centuries

Now cartographers love nothing more than new data

And today, I'm with my colleague, Steve Bernard,

who is our master cartographer at the FT,

to look at some exciting new data recently released

by some academics at the University of Colorado.

And the first thing that I did with this data

was load it up quickly into our computerised mapping

just to have a little look at what the data says

about how Phoenix has developed over time.

And as you can see, in the early 20th century

we start to see these little black dots, which

are these individual pixels showing that that land has been

And as you can see, as we go through the 20th century,

you get this amazing picture of sort of growth.

And this city structure, the city shape of Phoenix,

at just looking at this data and thinking: does it

And you got similarly very excited about it.

Yeah, the first time I saw it, I was looking over your shoulder

to be great to do for the whole of the US.

It's almost impossible to see to start with because you have

these very small little yellow pixels starting

So this is the railways flashing up as they were developed.

I got the data from the Library of Congress,

which had these amazing old maps, which they had digitised.

And I took these into the mapping software

and essentially traced them, every single railroad

so I could show the development of the railroad from the East

That's interesting by itself because now we're

about this GIS, this computerised mapping software,

is the way that you can layer information on top.

So this might be a story that people are familiar with.

But this is the first time that they've seen it.

in the late 1860s when the first railroad connected the West

of population along the West Coast from that point on.

San Francisco, Los Angeles, further north into Seattle,

they are growing exponentially from that point on.

And the amount of railroads which are developed

When people think about travelling around the US now,

invariably people think about internal flights.

not only was it essential for getting about,

helped to define the geography of the US.

at some of these old maps was just how important

it was for people to have maps of these connections.

I mean, some of these maps here are really, really beautiful

But they're all talking about the connections.

This map here, Baltimore and Ohio Railroad,

is actually titled Shewing the Connection, this kind

This one here, the map of the Canal and Railroads of the US,

it's almost like a still from your animation.
