It is my understanding that it's a raster based map,
although it has contours, they become pixellated as you zoom.
Mine starts with sat imagery, and draws vector data over it,
and that's how it knows your proximity with regard to trails,
roads, POIs, and contours.
I don't think you'll get the digital data.. AFAIK there isn't any.
The digital maps for sale are imagery of the same paper maps.
I had to calibrate and trace the raster data into a vector program myself.
I saw what it looked like overlaying satellite imagery four years later.
To cover Australia that way would be an immense task though!
