Help with OS maps

Hello all,

Please can anyone help me with the online OS maps?  I'm trying to edit a route and the start and end point aren't in the right places.  Is there a way to add a point that has a specific grid reference or to edit the grid reference of a point already there so that it moves?

I did manage to click on a point and edit the grid reference but I realise this didn't then mean it moved - it just meant that it now had the wrong grid reference :-(.

I've had a search around online and couldn't find the answer so any help would be wonderful

Best wishes,
Cristie

  I have submitted a few routes plotted with OS Maps desktop recently, and this has not been a problem for me, perhaps because the start and end points only need to be within 50m of the Slow Ways locations, and very few existing routes start and end in exactly the right place.

  In most cases there is a recognised path or road within this maximum distance, but if there isn't you need to plot the first two points without enabling snap to footpaths, and ensure that the snap function's first point is on a recognised path or road, which may involve trial and error. Snap to footpath works pretty well most of the time, but not all rights of way are in its data set, so sometimes you have to plot paths manually by turning it off.

  In my experience the OS plots still won't produce GPX files with elevation data, so you have to run the files through another tool such as https://www.gpsvisualizer.com/elevation before uploading them.
