In my travels through the wilds of the Interwebs, I’ve come across a nice little site called UMapper (www.umapper.com). The site lets me create maps using Google Maps, Microsoft Virtual Earth, or Openstreet, and bung all sorts of markers etc onto them. Afterwards, I can stick them straight into a post on this site. I can see this coming in handy for all sorts of Geocaching and travel-based malarkey.
This is an example of the sort of thing it can produce :-
Have a mess – you can click on the labels, and the route I put on it, as well as zooming and moving around in the normal way. Clever stuff eh? By the way, that’s a view of the Brecon Beacons (Corn Ddu and Pen-Y-Fan).
This is one little web app I’ll be making good use of 
this is a great app. thanks!
