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.

Hi Hugh,
Thanks so much for your help. I will give it a go. Great tip about gps visualizer too.
Best wishes,

Hi,
Hugh's post above is really helpful. I was having trouble uploading routes I'd exported from OS Maps. I had problems with getting them accepted (start / end points not matching) and then the elevation and (more importantly) distance information not showing up in Slow Ways.
Both these problems seem to be resolved by converting the file on gpsvisualiser.com before uploading. Looks like there might be quite a lot of routes on the site with missing distance and elevation info that will need fixing at some point. Some clearer user guidance on gpx files would be useful.

Just seen this thread after posting about elevation data not transferring through, and yes it would be great to have clearer guidance at some point about gpx files. I bought an OS subscription just to be able to create new routes for Slow Ways (I'm a paper map girl myself) so it's disapppointing to realise now that there's a known issue with it.
I'm not very techy but will have a go with gpsvisualiser for any future routes I create as long as it's fairly straightforward (and free!).

Hi Christine,
I've had a quick go at writing some instructions - you should be able to access them here:

Cheers Rob that's great! I'll have a go next time I'm creating a route.

Thanks again Rob, I've just followed your instructions and my new Haxsta two route has successfully uploaded complete with its elevation data. I'm delighted and very appreciative!
I have saved gpsvisualiser in my favourites for future routes.

I have done this by duplicating an existing route, that way the start and finish are bound to be right and it is probably less effort, especially if much of the route is the same as an existing one.

The instructions are good, but I have been using a slightly simpler method, which uses the default elevation data set. From step 3:
3: Go to https://www.gpsvisualizer.com/elevation
4. Under Solution #1: DEM database, use Upload a File, click on Browse and find your GPX file, then click Convert & add elevation
The steps from 5 onwards are the same.0
