[talk-au] Electric grid - how to tag

2013-06-28 Thread Mark Pulley
I'm tagging an 'electric grid' on the way into Finke Gorge National Park 
(Northern Territory). It has the same function as a normal grid, but rather 
than being made of metal bars, it has several electrified wires (same wires as 
used in electric fences), placed across the track, raised a couple of 
centimetres above the track by insulating material on both sides of the track.

I was thinking:

barrier=cattle_grid
electric=yes

Any suggestions for alternate tags? There is a tag electrified=yes, but on 
the wiki this is used to mark electrified railways.

Mark, 99% of the times electrification=yes is used, it has railway= 
there as well. Can we assume any rendering would look for the railway= 
tag first ?  I mean to say that no one 'should' assume electrification= 
applies only to railways ?


So,
barrier=cattle_grid
electrification=yes

would seem good to me.

By the way, never seen a grid like you describe, it goes across the road 
? And you drive over it ?

Sounds OK to me.

Yes to both questions. It's at the entrance to the national park, but as the 
track is in an intermittent river bed a normal grid or a gate won't work.

[talk-au] surface=unsealed in 4wd/dirt road tagging

2013-06-28 Thread Ian Sergeant
Hi,

I know we had some discussion over 4wd/dirt road tagging.

This ended up in the wiki as a recommendation to use

surface=unsealed

http://taginfo.openstreetmap.org/tags/surface=unsealed

I really can't see a significant reason here not to stick with

surface=unpaved

http://taginfo.openstreetmap.org/tags/surface=unpaved

When it is so much more likely to used, and therefore so much more likely
to be rendered, navigated, etc.  There are the other surface=* tags that
can be used if more specific information is available, but surface=unsealed
is obscure to no benefit IMO.

If there are no objections, I'll update the wiki.

Thanks,
Ian.
