When you click on the 'Show in Windows Live Local' button, MapPoint launches IE with an address that shows the locality.
The address string seems to contain the lat & long of the centre of the map plus some other stuff.
?http://maps.live.com/default.aspx?cp=51.855331%7c-2.236376&style=h&lvl=16&v=1 (obviously without the ? at the beginning!)
can anyone shed any light on what style, lvl and v relate to (I've sussed out that lvl seems to relate to the altitude but can't figure out an exact correlation between the actual altitude (in miles or kilometres) and what's required).
