It's probably fair to say that this version of the map wouldn't win
top marks for accuracy - he's got the Central line serving Hammersmith
in Map 1! - but it's an interesting idea.

To be fair I think that's because he has the Central line at a much
lower depth than the H&C so although it looks like it serves Hammersmith
in Map 1, that's just a quirk of a 2D representation of a 3D file.

Maps 2 & 3 show that it's not really showing Hammersmith.



There's clearly a bit of artistic licence at work to get around the
difficult bits, and he seems to be having major problems fitting some
of the interchange stations together with the lines, but I think this
is intended as an art project more than anything else.

An interesting variation of a familiar design, anyway...

I wonder whether he used actual depth information or just guessed.
Either way it's an interesting concept. It would be great if he could
supply a VRML file so we could rotate it and view it in 3D ourselves.
Then maybe the next stage could be to model the relative platform
locations and hence the station layouts in 3D... big task!

His biggest problem is that the station "blobs" are only at "surface"
level and don't descend to the tube lines. If they did, it would be much
more clear what's going on.

He's guessed.

For example, at King's Cross the correct order is Circle, Victoria,
Piccadilly, Northern from top to bottom.

If anyone wants to try a version for themselves, you can get a good
approximation to depth information from the escalator and lift
information in CULG.

However, there are going to be problems with stations like Oxford Circus
and Baker Street where two different lines meet on the same level. I
don't see how to solve that without ruining the point of the diagram.

It's incredible that trains can get up some of those gradients ;-)

Seriously, I could imagine LT using a version of this map as decorative
artwork on stations, or on one of their posters.

The obvious application would be as a spinning screensaver, sold on the LU
website and advertised on the front of the tube map. TfL would need to get
some (most?) of the money, though: he has clearly infringed their copyright.

Render the two running lines separately?

The problem seems to be that in plan, the deep tube/sub-surface
interchanges are in the right place, but they're not linked to the
lines. He needs to extent the interchange circles downwards as
columns to meet the deep tubes.

There's clearly a bit of artistic licence at work to get around the
difficult bits, and he seems to be having major problems fitting some
of the interchange stations together with the lines, but I think this
is intended as an art project more than anything else.

I wonder whether he used actual depth information or just guessed.

Judging on the W&C, it looks like he just guesstimated so that no
lines "collided" where they shouldn't. Of course, with something like
this is would be possible to represent the Camden Town junction
properly.

Either way it's an interesting concept. It would be great if he could
supply a VRML file so we could rotate it and view it in 3D ourselves.
