More info on this - it seems to be a bunch of people working for this 
company:


http://wiki.openstreetmap.org/wiki/%C3%96V_Firma_Mentz_Datenverarbeitung_GmbH

I've had no reply from the mapper that I tried to contact (although they 
have fixed at least one of the problems that they created) so I've tried 
again via direct message, comment on the firm's OSM wiki page and an OSM 
message to the company's main OSM account.


What concerns me is that they're still editing (with various accounts).  
It's relatively easy to trace straight lines from Bing, but it needs 
experience and interpretation (and a local survey!) to see how 
everything on the ground relates to everything else.


Based on their error rate so far I'd definitely still suggest that local 
mappers check their edits.


Cheers,

Andy

Yes, I looked at the first user in the list and the first page of changesets 
loaded with one close to me which is a railway platform apparently in the 
middle of a housing estate. 
http://www.openstreetmap.org/changeset/24439915

As it’s a U_Bahn entry I'm assuming its meant to be a platform on an 
underground line that’s just totally in the wrong geographical location. 
However the name of station 1 might suggest its someone practicing too.

Reverting and will look for others in the west mids area.

Greetings, all.

Mentz (aka mdv) is a German company that provides the journey planner used by 
a number of the traveline regions, as well as for Transport for London. As you 
may recall from my previous posts, a number traveline regions are now using OSM 
as the GIS. We found a problem (internally) with how railways were mapped, and 
mdv told us that they had found a way around it. It looks like that involved 
amending things in ways that are not appropriate.

Please pass the details back to me, and I will discuss it with them and also 
with the community if things need reverting.

Thanks Stuart.  All of my detailed comments so far have been on 
changesets.  I went through 
http://www.openstreetmap.org/changeset/26590071 in some detail (since 
I'm very familiar with the area), and also 
http://www.openstreetmap.org/changeset/26587435 and 
http://www.openstreetmap.org/changeset/26588170?way_page=2 .  The user 
concerned has tried to fix some but not all of the issues raised, but 
the biggest issue so far I think is the lack of communication with the 
UK community (I've not had any reply to messages to that user)*


Meaningful changeset comments (i.e. not just modified railway like on 
http://www.openstreetmap.org/changeset/26597441 ) would also help.  If 
these really are just source=bing (as that last changeset suggests 
then there are going to be some major issues with Bing offset).


Cheers,

mdv told us that they had found a way around it. It looks like that involved 
amending things in ways that are not appropriate.

Please pass the details back to me, and I will discuss it with them and also 
with the community if things need reverting.

Stuart

More info on this - it seems to be a bunch of people working for this
company:

http://wiki.openstreetmap.org/wiki/%C3%96V_Firma_Mentz_Datenverarbeitung_GmbH

I've had no reply from the mapper that I tried to contact (although they have 
fixed at least one of the problems that they created) so I've tried again via 
direct message, comment on the firm's OSM wiki page and an OSM message to the 
company's main OSM account.

What concerns me is that they're still editing (with various accounts).  
It's relatively easy to trace straight lines from Bing, but it needs experience 
and interpretation (and a local survey!) to see how everything on the ground 
relates to everything else.

Based on their error rate so far I'd definitely still suggest that local 
mappers check their edits.

Cheers,

Andy

 It looks like an attempt to dual the Robin Hood line went a bit wrong 
 and ended up slicing through an industrial estate and some areas of 
 housing (though I'm sure it was cock-up rather than conspiracy as 
 Sir Bernard Ingham would have said).  Looking at some other edits in 
 the same changeset, there are some other, less obvious, issues too, 
 which I've added to the changeset discussion:

 http://www.openstreetmap.org/changeset/26590071

 The most obvious problem seems to be tracing the railway in but not 
 joining properly to other features (such as crossings).  Some 
 information (e.g. cutting=yes) has also been lost.

 Another local changeset:
 http://www.openstreetmap.org/changeset/26587435
 has some similar issues.

 There have been a number of other edits, some with rather a lot of 
 deletions in them, including:
 http://www.openstreetmap.org/changeset/26613977

 All of these changesets could probably also benefit from a review from 
 local mappers to identify potential issues.

 Cheers,

 Andy

Mdv tell me that they have replied to SomeoneElse - presumably privately, as 
I didn't see it on the list - and have withdrawn the editor in question. They 
will also send a response to the list.

[Talk-GB] Railway edits in the UK that could perhaps benefit from a bit of checking.

An anonymous note adder (http://www.openstreetmap.org/note/267719) and
