Can you not download openstreetmap? Your bigger issue is that it's not really a nautical mapping system? In the USA you can have all the raster nautical and aviation maps for=20 free (cool).

I think you should consider some other options also: - Small embedded server which collects the information, with a handheld=20 system then connecting via http or similar. I like the PC Engines Alix=20 boards. - OpenCPN customised for your needs The top one is similar to something I'm working on. We=20 (http://www.mailasail.com) are building a small embedded router for=20 connecting all the communications bits on a boat together and we can=20 easily take in NMEA and repeat it via GPSD. I plan to either write, or=20 pay someone to write, a fancy javascript based instrument console=20 something along the lines of the ipad "NMEARemote" app. The goal would=20 be to use all the responsive magic that's easy to get these days to make = it scale from a phone to tablet screen. I think with a decent browser on your tablet you can fairly easily build = decent web apps these days, especially if you don't need to target IE. =20 To my eye this dramatically simplifies the problem because you can use=20 off the shelf components and focus on the software As an aside if anyone here is interested in extra work I have a fairly=20 big backlog of web based work. Probably need backbone+jquery skills=20 with a Rails/Mojolicious backend to talk to Good luck Ed W
