Now I begin to understand the complaints of Ross last year in July with respect to people doing tracing of roads. Given when I put a GPS tracked way in one of the points for doing so is to remove the dependence on yahoo for that way, and your previous post and Ross's reply suggest the only clean way to do that is to completely remove the old way, anyone who adds any road from yahoo is just making more work for GPS mappers. If this is the accepted correct practice then I think I might be jumping to Ross's side of the fence and frowning upon yahoo tracings of roads. This quote from his original email sums it up how I'd feel about it: "So my suggestion is instead of tracing roads, trace things that can not be easily surveyed. eg railway lines, rivers, powerlines." Of course that goes against the idea of getting a core amount of data in there to get people using things :/ I guess it just means those who want to make GPS tracks have to do even more work than they already do travelling around getting the tracks and collecting data. The price of quality I guess. -- =b _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
