Comment from GinaroZ
Can I suggest that you use the option in iD to turn off certain map features, so that you don't connect old railway lines to current landuse etc, thanks.

Comment from Glucosamine
Appreciating that plotting old railways is not without controversy, I have tried (mostly) to gap them where there is current development, but avoiding connection does seem a good idea. But you'll need to tell me more - I'm not clear what you mean by 'option in iD'.

Comment from GinaroZ
In the editor you are using (which is called iD) on the right hand side there is a "Map Data" option. In there is a dropdown for "Map Features" where you can deselect different types of features, allowing you to draw over them without connecting to anything else.

Comment from Glucosamine
OK - thankyou - I can see how to turn off features. But I had thought you were suggesting a way to turn off the possibility of connection. Is this not possible? If I simply turn off the features, then it would seem more difficult to see where I should be plotting and where I should not be plotting the route. I'll have a think about an appropriate strategy.

Comment from GinaroZ
Not sure if the possibility of connections can be turned off, though you can use the shortcut W to enable the wireframe view and make the lines smaller.
Surely the route you are plotting depends on the background imagery - either Bing or an old OS map? -
Comment from Glucosamine
Yes, I use wireframe at times. Issue is that plotting route needs both the old OS map (to confirm that the wrong possible feature on the aerial / from survey visit is not being followed in complex areas) and an indication of where modern development has encroached and erased evidence of the route. In areas such as you have commented upon, the OSM features ae often ore up to date than either aerial or openOS. So lots of toggling of layers ensues - and switching multiple layers on and off via tick boxes would be much slower. In practice, I try to avoid existing features and manually disconnect if they do connect. But evidently not always successfully. Do you know if there is an easy way to disable / adjust the 'snap' function - that would help if I could.
