The major problem is that the current implementation seems to be written
specifically for the Adobe SVG browser plugin.
If you dig around in the site to find the SVG map data and visit it with
Firefox, it'll render the map (slowly), but none of the interactive features
work. Not too surprising.

You might be able to do something with it given enough effort, but the Right
Thing to do would be to let Environment Canterbury know how unhappy you are
that all this useful information is bundled up in such an inaccessible way.
Along with the SVG map data, there's a list of platform numbers and physical
locations in another SVG file. I've attached a trivial parser for that in
the hopes that it might inspire someone...
