Re: [talk-au] OpenStreetMap in Government
I'm also very interested in 4wd trails - it's what 80% of my mapping consists of I think (that, and house numbers in the inner north of Melbourne) The current 4wd_only tag was one of the tags I proposed a few years ago - there was a massive barney at the time over the smoothness=* and surface=* tags, and all I wanted to do was mark roads that were clearly tagged as 4wd only (proper 4wd as in low range, high clearance). The surface/smoothness debate was interesting, but got in the way of the larger problem. I've come to the conclusion that the Australian mappers pretty much have to go it alone in this area - what the Americans and Europeans call a 4wd track would be a national highway for us (and we actually have a few legitimate highways and primary roads that are 4wd/seasonal closure type roads. I'm not a massive fan of the tracktype=* tag - it's a random number that is too subjective. There was an attempt in Victoria a while ago to class various tracks around the place as 4wd - the DSE/Parks Vic had a program where various 4wd club members were trained in what constituted an green, blue, black and double black road (very ski-trail), and got people out mapping that, but it all went to pot when it turned out that the DSE/Parks Vic guys were taking those results from the 4wd guys, and then either closing the roads to management vehicles only, or grading them so they were rated green. Pretty soon after that, the 4wd clubs got suitably annoyed, and stopped supporting the initiative. To the best of my knowledge, we still don't have a decent "subject to seasonal closure" tagging schema either - believe that Liz was at one time proposing something, but I think she's given up on OSM post license change. I'd be more than happy to help put together an AU only/AU based 4wd mapping set of rules and tags that we can use - if we can agree on something, I can also mod the hi-res/4wd maps I crank out for the Garmin devices to suit, and possibly even learn the Mapnik rendering stuff to implement the rendering side in Mapnik (seeing as DIY often appears as the only way the renderer gets changed). I wrote up some surface tagging concepts ages ago I thought might fly for handling the surface issue for 4wd tracks, as well as some general rules for tagging roads (eg: when off the beaten track, it's critical to mark the entire stretch of road as 4wd only or similar if there are no turns you can make to get off the road - often once you are on a 4wd road, you tend to be committed to going forwards...)

Re: [talk-au] OpenStreetMap in Government
Hi Matt, I think your conclusions is right, that we need to put an Australian standard together. It sounds like the ground work has been done (maybe even multiple times) but there has not been a clear acceptance of any particular schema. How do you think we should go forward with this? My suggestion is that we make a weekend of it, where we come together - where there are plenty of different types of 4WD tracks - and try and test the schema already made. I know I am still living outside of the country, so for me this maybe hard over the next couple of months. I am home in July for a couple of weeks and I am sure I could convince someone to lend me a 4WD. However it is winter, so it won't be the warmest weather! Maybe we could wait till summer? Would anyone be keen?

[talk-au] Offline OSM vector map engine for iOS
Gday mappers, I'm Li from Mud Map. We've just launched Mud Map 2, an iOS app that includes a OSM based vector map engine that works completely offline. It's been developed with a focus on outdoor recreational use, for example 4WDing, touring, hiking etc. Being vector, map data is fairly compact in size so the app has the whole of Australia. If you are interested in trying out Mud Map 2, I have a few promo codes here to give out. Li. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
[talk-au] Gates and access
Hi Mappers, Gates in many regional, state reserves or national parks have seasonal access. There's no official tag for this in the OSM wiki, right now options are access=yes or no If someone knows of the accepted way seasonal access should be tagged, that would great, Alternative, i'm proposing the access=seasonal tag.

Re: [talk-au] Offline OSM vector map engine for iOS
Hi I for one am interested as being forced to use Vector style maps on the iPhone is just to bandwidth hungry even though the iPhone might have enough memory. Be good as OSM is constantly changing. Count me in.

What's wrong with using the conditional restrictions
http://wiki.openstreetmap.org/wiki/Conditional_restrictions
"This field specifies the condition for which the restriction is
valid. Various kinds of conditions can be distinguished.
Time & Date: Use the standard syntax of the opening_hours=* tag. If
the time condition includes semicolons (";") the condition must be
enclosed by brackets. E.g. (Mo-Fr 07:00-19:00), (sunrise-sunset) or
(Jan-Mar)."
so access:conditional=(stuff)

Re: [talk-au] Gates and access
Hi, The seasonal tag exists, and is reasonable well used. http://taginfo.openstreetmap.org/keys/seasonal#map However, I also agree with Andrew's note, that if you have detailed information on access, then the opening_hours syntax and conditional restrictions is quite expressive.
