Neither you read the numerous replies which said that you should abandon

Plus, you are aiming to add a new type of a tag (value), and this action

I agree with your arguments. Then former?

Disappeared cannot be used, because it implies that the railway just
rolled itself and went home for Feierabend.  Or a UFO took it one night.

I don't like levelled for another reason: it is a word that is not easily
understood for those English-challenged, that is beginners. It's not a
word that easily translates into other languages. For this I would propose
removed. (Then it does not contrast with dismantled very much, but
frankly I am getting lost in those distinctions).

- proposed/planned

 There is actually a significant number of people that think we should _not_

But IIRC the question was how to map a former railway line that is
older/more damaged than mothballed / overgrown with trees, but not yet

I don't like gaps. ;-)
A former railway between Ittersbach and Pforzheim I could map
90% because there are enough traces (gravel, embankments, cuttings,
bridges, ...) but 10% are levveled for farmland or residential
ares including buildings. But the way can be reconstrcuted (straight
on or with known curvature) There for I need tags. Also for other
ways, where parts of it have coordinates because of streets
parallel to the old rail or directly on the old railway, other
parts still have real traces and other parts were easily
reconstructable from old maps. So a combination of parts with
disused, abandoned and the new tag will produce the whole network
for later special maps.

Next comes the historic society of blah city and they want to map the 
medieval street pattern. Half a year later they have a project about Roman 
times and want to map the castellum that once stood where now the city centre 
is.


For such real ancient things:
If they don't dig, they don't have coordinates ;-)
And if they can dig nothing else is there and it's worth to map ;-)

How are you going to find accurate coordinates for something that is no longer 
there like your railway? What you described previously were approximations 
based on other things.

How accurate is tracing lakes from landsat images?

How accurate is the PGS data most coastlines in OSM are based on?

How accurate is a GPS on a wooded mountain trail or in a typical city centre?

Look up map warping with your favourite search engine to see what people are 
doing with historical maps and known points.


OSM is full of inaccurate data.

Why?

Mailing lists work extremely well (except for digests) gatewayed to news 
servers (I ought to know, I'm reading this mailing list via a news

that also works quite well gatewaying to news servers.  That way,

We should probably take this discussion offlist, but my spare time is valuable 
and far too scarce, and I don’t want to spend it visiting websites just to see 
if there have been any new posts. 

 

I don’t believe I can configure the osm forums to email me notifications (or 
better still the content) for each post to the forum. If I can subscribe to 
certain topics, as you can on some forums, then I don’t believe that I can 
reply via email and would have to visit the forums to reply. The now 
discontinued MSN Groups did support emailing posts to members and coped with 
replies via email (as I note do the emailed Facebook notifications these days), 
so it is possible to have forums that are friendly to email users.

 

Having said that I’ve found something email related under privacy options on 
the OSM Forums so may give them another try, but even then it looks like you 
subscribe to topics rather than an individual forum, so won’t know about any 
new topics without visiting the site and browsing the new posts since last 
visit (I have 128 pages of new posts since my last visit on 17th September 
2009).

 

I’d even be happy with an RSS feed of new posts to any forum; anything which 
means I don’t have to visit the forum just in case there are any new 
posts/topics.

 

So, it isn’t all web forums I’m against. Just those where I have to visit them 
to read and/or post.

[Talk-transit] totally abandoned rails

2010-07-27 Thread Heiko Jacobs

Hello

For tagging the status of rail infrastructure there are in use:

- proposed or planned for rails not yet existing
- construction
- ... (nothing for rails in use)
- disused for existing rails not in use anymore
- abandoned (or sometimes dismantled) for rails not existing anymore, but
  traces already exist (gravel, embankments, cuttings, sometimes old
  rails crossing a way, ...)

... using to alternative taggings:
- railway=abandoned / abandoned=tram or
- railway=tram abandoned=yes

Sometimes the traces of a railway are very virtual:
- One or two streets/ways may follow the old railway and the railway
  declares why the ways have this position
- the edges of parcels of land may follow old railways
- scrub follows the old railway
- ...
using abandoned may be beyond the scope of the definition of abandoned ...

Sometimes no trace exist anymore
- because the whole area is covered by a new urban quarter where streets
  don't follow old railways ...
- farmland has occupied the old railway
- surface mining
- ...

using abandoned then, rendered in Mapnik slippy map and osmarender, this will
disturb the map from view of the not railway-historical interested ones ;-)

So I just searching for a suitable word for tagging traceless dissappeard
railways ...

A disturbed local community ;-) proposed two words
- historic, but this collides with existing historic tagging
- ancient, but this sounds very, very old, old greeks and romans ... ;-)
And both are not suitable to the existing scheme
planned-construction-...-disused-abandoned
which are independent from their age.
An railway may be abandoned 2 weeks or 100 years ago ...

So this words don't satisfy me ...
I'm searching something like traceless, virtual,
very, really very abandoned, ...

Does anybody has an idea?

  traces already exist (gravel, embankments, cuttings, sometimes old
  rails crossing a way, ...)

 ... using to alternative taggings:
 - railway=abandoned / abandoned=tram or
 - railway=tram abandoned=yes

 Sometimes the traces of a railway are very virtual:
 - One or two streets/ways may follow the old railway and the railway
  declares why the ways have this position
 - the edges of parcels of land may follow old railways
 - scrub follows the old railway
 - ...
 using abandoned may be beyond the scope of the definition of abandoned ...

 Sometimes no trace exist anymore
 - because the whole area is covered by a new urban quarter where streets
  don't follow old railways ...
 - farmland has occupied the old railway
 - surface mining
 - ...

 using abandoned then, rendered in Mapnik slippy map and osmarender, this
 will
 disturb the map from view of the not railway-historical interested ones ;-)

 So I just searching for a suitable word for tagging traceless dissappeard
 railways ...

 A disturbed local community ;-) proposed two words
 - historic, but this collides with existing historic tagging
 - ancient, but this sounds very, very old, old greeks and romans ... ;-)
 And both are not suitable to the existing scheme
 planned-construction-...-disused-abandoned
 which are independent from their age.
 An railway may be abandoned 2 weeks or 100 years ago ...

 So this words don't satisfy me ...
 I'm searching something like traceless, virtual,
 very, really very abandoned, ...

 Does anybody has an idea?

Re: [Talk-transit] totally abandoned rails

2010-07-27 Thread Greg Troxel

   For tagging the status of rail infrastructure there are in use:

I usually think it's good to look at existing practice by others.

On USGS maps, and in US legal usage:

  out of service: rails still exist, but no trains.  shown as regular
  rail on USGS maps.  OSM has no  aparent term for this.

  abandoned: this is a legal distinction, where ICC has approved
  abandonment.  shown as dashed rails.  tracks may or may not be
  present, but typically some track remnants.  OSM says disused

  old railroad grade.  Definitely legally abandoned, definitely no
  rails.  often just traces of embankment.  shown as dashed line, no
  hashes, but there are definite signs on the ground that there used to
  be a railway (obvious to any train fan).  OSM says abandoned

beyond that, this road used to be a railroad doesn't show up on normal
renderings.  I'd be all for railway=historic to record previous route,
and expect it not to be rendered on maps for normal people.  ancient
isn't good, because it's not that it's old, but that it's no longer.
There are rails near me from 1844 over which dozens of trains run daily,
and some from 1876 or so that are very hard to find.  (The Fitchburg,
and the Marlboro Branch, for the NE train nerds.)
