I just noticed that a huge section of NCN national route 75 has disappeared. There's a note on the OpenStreetMap data (added by user Mappo?) that says "closed due to reopening of railway line. Due to be replaced with new route by 2010". I guess it has something to do with this Airdrie-Bathgate Rail Link, which I've never heard of before. I'm not quite sure exactly why Edinburgh needs a fourth rail link to Glasgow (that takes 24 minutes longer than the existing 50 minute train) but it brings up an interesting question - given that every cycle map apart from OpenStreetMap will show NCN75 as being complete, people looking here will automatically assume that OSM is incomplete... maybe some alternative rendering for closed routes would be appropriate.

For some reason josm doesn't support multiple audio notes, so here's a Python script that will annotate a GPX track with your jpg and wav surveying notes. Note you'll need to run josm with the patch to allow it to load GPX files with namespaces.

Including the code here in <pre> tags messed up the formatting so try: gps-fix-gpx-links

I'm trying to map out some of the Sustrans cycle routes around Edinburgh so that they appear on opencyclemap. In the last few weeks I've cycled ncn43 to Croy (which was already mapped), rcr73, and ncn76 as far as Dunbar. Next on my hitlist is ncn76 from Dunbar<->Berwick, the ncn1 from Berwick<->Seahouses, and the ncn1 north of Edinburgh up towards St Andrews.

My kit: Garmin Etrex yellow+bike mount, I use gpsbabel to get the tracks off the gps and into Linux, and josm to do the editing. I'm finding it hard to keep track of stuff on the bike without lots of stopping and starting - ideally there'd be some one-click bluetooth earpiece type voice annotation solution, but for the moment I'm experimenting with taking voice records and photos on a SE k750i phone, which at least records individual files with accurate timestamps.
