This means that the separate track should be removed for the 3 cases I
listed, or not ?

 Abandoned - The track has been removed and the line may have been reused
 or left to decay but is still clearly visible, either from the replacement
 infrastructure, or purely from a line of trees around an original cutting
 or embankment. Use railwayhttp://wiki.openstreetmap.org/wiki/Key:railway
 =abandoned http://wiki.openstreetmap.org/wiki/Tag:railway%3Dabandoned.
 Where it has been reused as a cycle path then add 
 highwayhttp://wiki.openstreetmap.org/wiki/Key:highway
 =cycleway http://wiki.openstreetmap.org/wiki/Tag:highway%3Dcycleway.
 Consider adding a end_datehttp://wiki.openstreetmap.org/wiki/Key:end_date
 =* tag or more specifically a 
 railway:end_datehttp://wiki.openstreetmap.org/w/index.php?title=Key:railway:end_dateaction=editredlink=1
 =* tag.

 It applies even if it now looks like a cycleway or anything but if you can
 still clearly see where the railway has been.  If Mapnik, Garmin or other
 doesn't display or use that correctly, they say that you must file a
 renderer bug.

 Cheers,

No, highway and cycleway should not share any ways. The only thing which
may be acceptable is reusing the same nodes for two different ways, but
only if they are on exactly the same location, which is actually quite
rare. In quite a lot of cases there will be an offset, or it will diverge a
little bit from the original railway track.

Re: [OSM-talk-be] Abandoned Railways / cycleways

2013-04-14 Thread Marc Gemis
For the first two examples there is no doubt that there are still remains
of a railway, but
I still wonder whether it makes much sense to leave the railway tag on this

http://www.openstreetmap.org/?lat=51.1060394346714lon=4.379757642745972zoom=17

especially on the parking area and to a lesser extend in the first part
parallel to Voetweg 32.
If the line was not on the map, I would never have known that there has
been a railway. I don't know of any visual clues there.

Of course the Spoorweglaan gives away that there used to be a railway :-)

[OSM-talk-be] Abandoned Railways / cycleways

2013-04-13 Thread Marc Gemis
While mapping my RWN walk near Hulshout / Westmeerbeek I noticed that there
were 2 cycleways next to one another, running from north to south:
http://www.openstreetmap.org/?lat=51.063594818115234lon=4.8265814781188965zoom=16

One was simply mapped as highway=cycleway, the other had more tags and was
also part of an RCN relation. Further investigation showed that the former
used to be a railway=abandoned, but was changed to a cycleway in December
2012.

The ways are pretty long, running from Herentals to Leuven. The abandoned
railroad way has ID 116738269.

I decided to reverse that way to railway=abandoned, but I'm not happy with
it. It shows to parallel lines on a map (I know, don't tag for the
renderer), but wouldn't it be better to add the railway=abandoned to the
cycleway. ?

Similar situation here:
http://www.openstreetmap.org/?lat=51.06616973876953lon=4.476719498634338zoom=17

and here
http://www.openstreetmap.org/?lat=51.1060394346714lon=4.379757642745972zoom=17
in this case I wonder how you can see it, no remains are left.

So why two lines for an abandoned railway and the cycleway/footway on it ?
Can't they be combined ?
