Mapping software for Linux
Google and I don't seem to like each other this week, so I'll ask here...
Is there any decent mapping software for Linux that is comparable to Delorme's Street Atlas or Garmin's Mapsource products for Windows? It does *not* have to be able to sync maps or share data with my GPS receiver, although that would be a nice bonus. The need for mapping software is pretty much the only remaining obstacle that keeps me chained to a predominantly Windows box.
If you reply, keep in mind this point also. I don't want to sound like an adversarial asshole right off the bat, and I apologize in advance if that's how I sound, but I also want to avoid what usually happens when I've asked people this question in the past. Don't send me URLs for Mapquest, Yahoo Maps, or any other "internet only" mapping options. If I have to be online to use it, it is *not* a viable option, and is not comparable to Street Atlas or Mapsource.
