Multimap is my Friend

»

I've talked before about how I prepare for walks. In essence I use Streetmap's 1:50,000 OS maps to look at Rights of Way and Google Maps and a third party "mash up" to define the route as a set of waypoints in a GPX file which I can then upload to my GPS. For more on this go read my previous posting.

I was discussing this on Outdoors Magic and someone pointed me to a page which displayed 1:50,000 OS but without the clutter of Streetmap. When I looked into it I discovered they were using Multimap's Open API and their relatively new addition of OS maps to their library.

So on Wednesday I started playing around with it and it looked very promising. Thursday night I started writing an application for putting waypoints on a map and today I blitzed it and I've now got to the point where I can put a set of waypoints on a map, name them if required, delete them, move them about if they're wrongly positioned first time, and finally, when I'm happy with the route I can get it sent to me as a GPX file ready to import onto my GPS.

It's still a bit clunky. It only works completely on Firefox, passably on Opera and it's broken on Internet Explorer but I'm getting there. I won't post a link now as we're still testing it.
