A while ago I wrote a mapping application for the Zaurus for the USA using census databases and converting them into a very compact form (every line and polygon in just over 1Mb for all 50 states - I didn't get to text or POIs): http://homepage.mac.com/tz1/.Public/zaurus/zmapper.tgz (I've done a few bugfixes since, but haven't uploaded it, and there are new census databases so some URLs need changing). Actually it is Qt(3), so will work on anything which has that installed - Linux, Mac (X - I need a real xor function to do the polygons), Cygwin. I've seen Qt for the Nokia, and was planning to give it a try. I could port it to GTK. It isn't complete, but will show roads, lakes, rivers, cities, parks, etc. - every one in the census database and updates very fast and uses a very compact format. It saves the track and I used to wardrive with circles indicating the access points kismet for zaurus found. These are vector maps and no further downloads are required after the specific county is converted. I may not have included the COPYING file, but it is under GPLv3. Anyone want to help?
