How can I view a route from a .kml file overlayed on an Ordnance Survey map?

Question

I am taking part in a 100K event later this year, and the organizers have made available a .kml file of the route downloadable from here. This is great, but I want to view this route on a UK 1:25000 Ordnance Survey (OS) map, the kind that Bing Maps presents, when you choose Ordnance Survey as your display option. As is, I can only view the route in Google Maps which lacks much of the information than an OS map provides.

I can compare Google Maps displaying the .kml route side-by-side with Bing Maps displaying the OS map, but is there a way of pulling the .kml file into Bing Maps? Or is this functionality available elsewhere?

Answer 1

I believe that what you are looking for is,

• Gavin Brock's Ordnance Survey Map KML Overlays for the UK
• Same one found here.
• The Charles Close Society for the Study of Ordnance Survey Maps

Any of these should put an Ordnace Survey overlay into Google Earth and then you could combine that with the .kml file you already have.

Answer 2

You can convert to GPX eith with Chris h's suggestion above or http://gpx2kml.com/ will convert Kml to gpx and back.

I really like Viewranger, is a great phone app that will allow you to have GPS navigation with your route overlayed onto an OS map. I'm guessing that you're after a more desktop approach though.
