I am going to France next week and need to drive from Paris to
Blannay, France.  I am taking my GPS and would like to have the
coordinates of Blannay programmed in to make it easier to find.

Hi there holstein13

The co-ordinates you require are 47:31:48N, 3:47:03E

You can obtain this information for most places in the world using
Multimap at
http://www.multimap.com/

In this case I chose "France" from the top-left drop-down Quicksearch
menu, and then once the page refreshed entered "Blannay" in the town
field, giving me the following URL (with apologies for its length!):

http://www.multimap.com/map/browse.cgi?client=public&db=FR&overviewmap=&client=public&Submit.x=18&advanced=&addr2=&Submit.y=3&addr3=Blannay&cname=France&pc=&X=420996&Y=5997501&scale=50000&place=BLANNAY,+BLANNAY,+89200&coordsys=mercator
Below the displayed map you will find a set of information including
the latitude and longitude co-ordinates above.

I hope this helps, and in future you should be able to get the
required information for yourself. Enjoy your trip to France!
