[talk-au] Adelaide out of copyright street directory

[Matt White]

I'm also a serial offender for not using the survey tag, but again, I 
upload all my traces.

I do a bit of yahoo tracing as well, and don't directly mark that either...

But then again, I don't go and screw around with any existing nodes and 
ways unless I've been there... however I have been known to add the road 
way in off a random trace that wasn't mine if I've been in the area 
(sans name generally) and the trace quality is good enough.

It's an intractable problem - forcing a source=survey/yahoo/made_up tag 
still won't solve the issue as the source tag needs to be kept up to 
date, and you can link the source tag to the individual tag within a 
node (eg: the way is yahoo sourced, the name comes from the MMBW maps, a 
local marked it one way through local knowledge, and someone added speed 
humps using a GPS trace/waypoint setup.

So the source tag contains a variety of sources, and no way of 
determining what applies to what.

In the end, the crowdsourcing approach *should* sort out the wheat from 
the chaff eventually, but no doubt there will be some hiccups along the way.
