text: I wouldnt necessarily say that. There was something on the wiki awhile back about how its ok to use map data from none commercial maps or indexes. Id think that especially applies to goverment maps, which are in my opinion and in most cases ive found public domain. Even if it doesnt explicity say so. Its sort of a given. Otherwise, quit a lot of things in openstreetmaps wouldnt exist. Including bus routes, any official boundary for anything, any type of border, lots of road names/access restrictions,  or anything else official for that matter. So I see people use goverment sources all the time without issue. Even if the page refrenenced doesnt explicity give consent. Its a given because its the government. 
  
  I'll try and find the specific reference if needed, but I dont think I should have to.
