Yeah but I don't think I can modify your maproulette challenge, are you
able to?

There's another thread ongoing on this list about importing suburb,
localities and LGA boundaries.

Re: [talk-au] Adding lane tags to major roads

[Martijn van Exel]

That is a good point. The query would probably be easy enough to modify.
Something like this...

[timeout:190];
area[name=“New South Wales"]->.a;
way[highway~"motorway|trunk|primary"][!lanes][!"lanes:forward"][!"lanes:backward"](area.a);
out body geom qt;

I think it needs to be pre-processed a bit more to weed out the very short 
segments. And perhaps work on areas where lanes actually matter (urban) first. 

I was looking at how to slice that and got interested in the status of 
administrative boundary relations for Australia. It seems to be inconsistent, 
for example in South Australia there is pretty good (but not complete) coverage 
of admin_level=6 http://overpass-turbo.eu/s/EmZ 
 and even one admin_level=8 
(http://overpass-turbo.eu/s/En0 ) but in other 
states the admin_level=6 coverage is pretty sparse or absent 
(https://imgur.com/a/gmUJs2r , query at 
http://overpass-turbo.eu/s/En1  but watch out, 
it’s a lot of data). If you all think this is useful to fix / complete perhaps 
we can set up a page to coordinate. I’m happy to help.

[talk-au] Announcing: OpenStreetCam competition

[Martijn van Exel]

Hi folks, 

We (Telenav map team) are holding an OpenStreetCam image capture competition. 
In case you're not familiar, OpenStreetCam is an open source / open data street 
level imagery collection platform for OSM. It is widely used to help improve 
OSM (through iD and JOSM) but there is not a lot of coverage in Australia yet. 
So with this competition we’re hoping to start to change that. 

More details here: 
https://github.com/openstreetcam/competitions/wiki/Australia-Competition-Dec-2018
 

 

The TL;DR is: collect as many OSC images as you can between now and Jan 31, the 
top 3 contributors get $100 / $25 Amazon gift cards!

Happy mapping / capturing!
Martijn

PS in case you’re in NZ, we have a separate competition staring there as well, 
https://github.com/openstreetcam/competitions/wiki/New-Zealand-Competition-Dec-2018

This routing error is from having foot=yes on a way across the water.

If the foot=yes is only on the relations used for the ferry routes than it 
should go away.

[talk-au] protect_class=24 and Indigenous Protected Areas

[Andrew Davidson]

I've noticed that listed under protect_class=24 (political protection) 
for Australia are Indigenous Protected Areas. This is incorrect, as 
Indigenous Protected Areas are conservation areas owned or managed by 
Indigenous groups and have an IUCN Category assigned to them, they 
should be tagged protect_class=2,...,6.


Does anyone have a view on what would fall under protect_class=24 in 
Australia?
