Projects such as OpenStreetMap make me wonder: isn't there a community-driven, open-source project that allows to do all this offline? In general, could anyone point me to offline alternatives, where you simply download all the data? In some situations using a static snapshot could prove good enough.
You can download the raw data from OSM easily. Get it here: http://planet.openstreetmap.org/ . However that's a 20GiB compressed XML file in their schema. You could download the data and pre-generate your own tiles and save them, but that would take a lot of space (i.e. Terabytes). You could download the OSM data to your computer and set up mod_tile (the render on demand server) locally and browse your own computer to see the tiles.
If you have a garmin GPS you can download the garmin map files based on OSM for your gps from this site http://download.geofabrik.de/osm/ . You can also get navit files from OSM which works on the open source navit satnav programme. Neither of those are browser based tiles though.
