I believe this section of road has a cycleway alongside it which is missing from the map/data. Local survey required.

A cycle route is signed here - missing from the map. It's identified with a blue '1' (legally a 'regional route') and would appear to have been signed within the last year or so. This isn't mapped by Sustrans. Should be surveyed and mapped if it goes somewhere significant.
(Signs were identified between this marker and Constarry Road, then along Constarry Road to Croy station, where an 'end of route' sign exists. No exploration was made northwards from here.)

Edinburgh speed limit changes: Is there an end of 20mph zone sign here? The beginning of the road should be signed 20mph I think, and it certainly is leaving a 20mph road, but I'm not sure there are any other signs as Queens Drive comes over the hill past the loch. The bigger sections of Queens Drive just to the west of this note are still 30mph I think. There's currently no speed limit recorded on this section of Queens Drive. This may be an accurate reflection of what's on the ground.

Edinburgh speed limit changes - quick check of zone edge required here:
Full zone 1 speed limit boundary survey carried out today, and speed limits changed, but I forgot to check this small network of streets (Elder Street, St James Place). York Place is still 30mph. Leith Street here is 20mph. Where is the zone edge - at the entry to Elder Street from York Place or at the exit of St James Place onto Leith Street?

I believe that there's the ongoing development of a new path link here (unmapped) linking Moray Park Terrace to Lochend Butterfly Way (see discussion http://citycyclingedinburgh.info/bbpress/topic.php?id=12733 ).

There's a disused railway here, converted to an access road, used by the public, linking northwest to southeast.

Has Bawbee Bikes (mapped here) closed? Recorded website is gone. Known phone number is dead.

Mount Stuart estate paths, attractions, tracks, are only partially surveyed - many missing from OSM. Although these have access only to customers (who pay for access to gardens and house) it's a key tourist attraction in the area and a good survey would be helpful.
