Re: [Talk-GB] Vectorising StreetView buildings in Southwark

[Tom Chance]

I have run a comparison with TimSC's mapseg, if anyone is interested. I
think my process comes out with better results:

http://wiki.openstreetmap.org/wiki/User:TomChance/VectorisingStreetView#Comparison_with_Mapseg

I'm still stumped on how to do the first part of step 4 using GDAL, mind.
I've gone into the IRC channel a couple of times without getting any
response. If anyone could give me a pointer I'd appreciate it.

In getting from EPS->DXF->SHP I end up with a shapefile without co-ordinates
(i.e. QGIS shows the top left corner starting at 0,0) and that is only very
small (i.e. the area that should be a few miles across appears to only be a
few meters across).

Where do I start in transforming the shapefile to be the right scale and
then translating the coordinates to shift it to the right part of the world?

Regards,
Tom

I passed the Mayfly on Saturday while walking the Test Way between
Andover and Mottisfont. That photo was taken where the railway line
meets the A30 just North of Stockbridge.

Thanks to everyone who replied, ncn_ref=246 it is.

[Talk-GB] Can I post about an iPhone OSM app

[Chris S]

Greetings,

I am working on an offline OSM browser for the iPhone/iPad.  Do people
think it would it be acceptable to post details to this list if/when
it is on the App Store?  I thought I should ask before posting...

It is a vector based browser with on-the-fly configurable rendering
for custom map views.

Let me know what you all think,

Yep. Several places have local networks (we tag them with lcn_ref) and it is 
*really* confusing when they use blue or worse still, in Gloucester, red. Mind 
you the Oxford signs I've seen are so faded I'm amazed you can tell they're 
blue at all. ;)

Gwynedd has a curious part-local, part-regional set of routes with 
white-on-green signs. Some lovely cycling, though.

[Talk-GB] NCN numbering

[Richard Fairhurst]

Apologies for thread breakage - the otherwise excellent Nabble has fallen over.

All white-on-red numbered routes are National Routes and should be tagged with 
ncn_ref (or the relation equivalent). This includes all the new three-figure 
routes.

White-on-blue are Regional Routes. These are being phased out and will all 
either be renumbered as National Routes (usually three figures, though I know 
of one existing and two proposed renumberings from Regional to two-digit 
National) or withdrawn from the NCN entirely. Don't expect it to happen 
overnight, though. 

It's a bit confusing right now but should resolve itself into something more 
understandable in time.

Usual proviso: local councils have been known to get the colours wrong on 
occasion!

Re: [Talk-GB] A quick question for the cyclists

[Richard Mann]

Clear as mud. I think what you are saying is that it is a regional
route, and "should" therefore be an rcn, but that it will be
nationally distinctive number, so you could call it an ncn.

I'd probably call it an ncn, since the distinction between regional
and national routes is a bit arbitrary, and if it's all one national
numbering system then it will be less confusing to call it all ncn and
leave people to infer meaning from the number of digits if they want
to (in the same way that we do for A roads).

I've never seen that proposal before, I'm not sure if there's been any 
previous discussion of it anywhere.
But it does all seem to be a good idea. I think there is a need for some 
sort of boundary tag for nature reserves and other protected areas, and 
tagging them with their designation.
Though I'm not sure if "reserve" is the best word for it, it seems a bit 
ambiguous.


There is an alternative proposal here for boundary=protected_area: 
http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dprotected_area
But IMO that proposal is overly complicated, trying to cover everything 
in the world, and using numbers instead of words for the designation/status.

Re: [Talk-GB] A quick question for the cyclists

[Graeme Wilford]

It looks like 3 digit NCN "national route" references are replacing the
two-digit, per-region NCN "regional routes".

From
http://www.sustrans.org.uk/what-we-do/national-cycle-network/route-numbering-system


"For the purposes of numbering Regional Routes, the UK has been divided into
ten regions, with Regional Routes numbered 10-99 within each region, number
allocation being generally based on the larger counties. The signing
convention will be the same as for the National Routes except for using a
blue, rather than red, number patch (as pictured above). Over the next five
years Regional Routes will be re-numbered using three digit National Route
numbers."

NB. All OSM-tagged ncn and rcn routes are actually national cycle network
(NCN) routes with ncn indicating NCN national route and rcn indicating NCN
regional route. Dropping regional route designations altogether will further
confuse this.

Cheers,
Wilf.

Hi Andy,

You were in the same place as me this weekend more or less!!! I recognise that.

I walked from Andover to Winchester on Sunday afternoon and walked a small 
section of this cycle track near the Mayfly at Fullerton. You weren't in the 
area then?

I'd just suggest ncn_ref=246. I think, rather like the A road system, route 246 
is a branch off route 24 which IIRC goes from Southampton to Salisbury.

Re: [Talk-GB] A quick question for the cyclists

[Gregory Williams]

Don't worry. There are a number of three-digit national routes appearing
now. That doesn't mean that there are at least 246 national routes. It's
just that the numbers have a little significance in the scheme of things,
like they do with road numbers.

So, in short, it's NCN.
