Hey, that sounds like a great idea, publishing trail maps!
My first reaction though is that I wonder what kind of copyright protection those trail maps have on them (unless of course you authored them).
The original version of the software that processes these maps is attached somewhere above (it's a perl script). I have to dig around for the latest set of perl scripts that generates the tiles and stacks them. I'll have to attach that later as it's not on the machine I'm logged in on. It will definitely require reworking as it assumes that you're reading in NOAA's nautical charts that have a particular format. If you're adept at perl, you can easily rewrite the appropriate subroutines.
I would love to help out, but only if it's legal to do so obviously. If these aren't your trail maps, I'd like to see a license agreement, and if it's from a published book then you'd have to get the publisher's written permission to publicly post this stuff (which is not likely to happen).
Absolutely, that's why I put them there. I know harborfinder.net doesn't exactly tell you how to access those tiles, but you can fetch them yourself by accessing the URL for each tile. That would be super tedious. Sometime soon I hope to make regions of tiles available as downloadable archives, but I'm not there yet.
Interesting... care to mention what part of alaska, lat/lon or city names? I'll take a look. Not sure if this is the case, but it could be an issue with memory management in maemo mapper, and the fact that all of the harborfinder.net tiles are 4-channel pngs, and they still need to be optimized for web distribution (something like a paletted gif with transparency).

Thanks! Again... more work to be done, but your comments help. I'm curious about the problematic region in alaska. There seems to be some bugs in the utility that I use to convert the charts to PNGs, which is why some parts of the Gulf coast have black artifacts (esp. around rotated charts), so I'm currently looking into that.

Again, I'll need to upload my latest set of perl scripts. I'm still in the process of converting this stuff to Java.
