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.

Both names escape me at the moment. 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 :( -- Rebecca Richards, CCSA CCSE, Security Consultant, e-Secure Pty Ltd "Secure in a Networked World" Phone: (02) 9438 4984 Fax: (02) 9438 4986 Grnd Floor, 71-73 Chandos St Mobile: 0412 823 206 St Leonards NSW Australia Email: [EMAIL PROTECTED] ACN 068 798 194 http://www.e-secure.com.au -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
