Perhaps it might help me find a means of improvement. However, until a map program supports the caching of map data and not substituting an error screen for a perfectly good map screen just because of a glitch in location, I'm not too motivated. There are too many gaps in cellular data coverage where I live to make Linux ap maps useful and it's actually a problem throughout all of rural Idaho. I'm tired of using and supporting spy phones though so I'll just carry a dedicated GPS (even my old Garmin) when I need to know my location until things improve.
