[talk-au] [OSM-talk] RFC: Tagging and rendering Australianhighwaynumbers

[Brent Easton]

Hi Ian,

need some input from Cameron on what is easiest to parse when rendering. Having some tags with 1 char and some with 2 may require a seperator to make things easier.

Here is another version with your changes

ref:au=NR-1     Highway 1 - (black on white shield)
ref:au=NH-31    National Highway - (yellow on green shield)
ref:au=MR-2     Metroad (blue on white hexagon)
ref:au=S-151    State Route  (white on blue shield)
ref:au=T-5      Tourist Route (white on brown Pentagon)
ref:au=A-1      A Roads in states that have them (yellow on green rectangle)
ref:au=B-2      B Roads in states that have them (yellow on green rectangle)
ref:au=C-3      C Roads in states that have them (yellow on green rectangle)
ref:au=M-4      Motorways(yellow on green rectangle)


Is this right that the motorways you are thinking of are part of the Alphanumeric system and appear on a green rectangle? In Sydney, M2, M4, M5 etc. are actually metroad numbers, there are no 'motorways' as such, they are always part of a different tag, either a Metroad in the city, or NR or NH in rural.

Personally, I think we should probaly merge NR and NH and just have H- for Highway. H-1 can be handled as a special case by the renderer and show the white shield instead of green.

It makes sense to me to have A, B, C and M all using their own tags, even though they will all be rendered similiarly (ref:au=AN-B3 for Alphanumeric type, B3 - Yuk).

Multiple references should use ';' eg. 

 ref:au=T-5;T-6 

for a road part where both Tourist drive 5 and 6 run.

Cheers,
Brent.
