Re: [talk-au] Murray River mapping by a newby?

2020-04-17 Thread Sebastian S.
Another aspect to work on is to write down or brush up some of the agreed ways 
of doing things.
In my experience this is a good opportunity for a newbie. Someone new reads 
wikis and instructions differently. Finds mistakes or unclear bits.
Together with the mailing list as a feedback pool this is another area to work 
on.
However not is not everyone's cup of tea.

Hi Ian,
A warm Welcome from me too. The fact that you reach out before you start 
editing is a good thing.
Similar Ed I can't comment on your particular question but this is certainly 
the right place to seek advice for questions.
I myself stay away from complex large relations.

Re: [talk-au] Practicality of mapping high-speed motor-traffic routes as cycle routes

2020-04-17 Thread Sebastian S.
Hi, thanks for the Strava point. A subset indeed but a substantial use.

I agree with Andrew that tagging family friendly routing is not something for 
the map but for a routing engine.

Maybe there is a tag combination similar to discouraged and surface quality to 
indicate the proximity to high speed traffic. But then again as Andrew said the 
highway/motorway tagging dies indicate that already.
