Can I add just as a warning, don't use their maps for anything remotely
commercial unless you pay them, and even if it's free, be very carefull.

Map companies are very sensitive about their data, it's their main
asset, and they spend millions aquiring the data. They often have fake
streets and landmarks in the maps, so they can prove people are ripping
off their data.

I'm assuming you're talking about the Auslig Raster 250K maps.

They're in a proprietary format (ECW), but the company that created the 
ECW standard has released a Windows SDK.  I reckon it would be possible 
to reverse-engineer this SDK, so that we can have a Linux interface to 
the ECW format.

In any event, the Auslig application supports map export to png and jpg 
formats.  This is mighty handy for those of us who use Linux-based GPS 
applications.  However, the maps need to be "geo-referenced" before they

can be used (the geo-referencing information is stored (I think) in the 
ECW files) by linux GPS apps, which is a pain, and I often get it wrong.

  (There's something going wrong when you're driving down a country 
road, and the map shows your position as being off the road by some 500 
metres or so).  None of the linux apps that I've looked at support ECW 
maps :(

I won't be in GPS nirvana until I can find an app that supports these 
maps :(
