Re: [OSM-talk-be] Railway data accuracy , age and origin
What is wrong with it? most what I see looks still up to date. Could you be more specific ?

Re: [OSM-talk-be] Railway data accuracy , age and origin
It's useless to draw two ways for a single double-track railroad line: almost everywhere all tracks are mapped seperatelyto not use a detailed schema for complex station grids: all detail is mapped in most stationsWhen on a four track group of lines - and this is the case on L36/L36N between Leuven and Brussels - the two inner tracks are another line than the two outer ones, I propose to nevertheless draw them next to each other, nicely parallel as prescribed in the How to draw a motorway page.: can it become more outdated? And what about the voltage, frequency, gauge, usage, ref, name, ... tags? Which tags should be used in Belgium, which not, en which values should they have? And what about the relations and the tags they should have? Also this page could use some rewriting...http://wiki.openstreetmap.org/wiki/WikiProject_Belgium/Railways Regards, Stijn From: Glenn Plas gl...@byte-consult.be To: Stijn Rombauts stijnromba...@yahoo.com; OpenStreetMap Belgium talk-be@openstreetmap.org Sent: Monday, January 12, 2015 8:05 PM Subject: Re: [OSM-talk-be] Railway data accuracy , age and origin What is wrong with it? most what I see looks still up to date.

Re: [OSM-talk-be] Railway data accuracy , age and origin
Thanks, I actually missed that motm edition. It is because it's so detailed I wondered if that was an import job or not. I wonder how 'open' NMBS would be if we asked for their digitized data... I'm working all angles at this moment.

The wiki [1] mentions a GPS file and in the past there was some discussion about that, but I think the majority is mapped from BING imagery. I know I have done a lot of that. And it will probably not be NMBS you want to talk to but Infrabel.
